  • Matching first set of elements with xpath...

    - by Ugo Enyioha
    I have an xml document that looks like this. <foo> <bar type="artist"/> Bob Marley </bar> <bar type="artist"/> Peter Tosh </bar> <bar type="artist"/> Marlon Wayans </bar> </foo> <foo> <bar type="artist"/> Bob Marley </bar> <bar type="artist"/> Peter Tosh </bar> <bar type="artist"/> Marlon Wayans </bar> </foo> <foo> <bar type="artist"/> Bob Marley </bar> <bar type="artist"/> Peter Tosh </bar> <bar type="artist"/> Marlon Wayans </bar> </foo> I would like to construct an xpath that returns only the first set: <bar type="artist"/> Bob Marley </a> <bar type="artist"/> Peter Tosh </a> <bar type="artist"/> Marlon Wayans </a> How would one go about this? I have tried //bar[@type='artist'] but it's obvious there's more to this. Thanks in advance.

  • Find position of a node within a nodeset using xpath

    - by Phil Nash
    After playing around with position() in vain I was googling around for a solution and arrived at this older stackoverflow question which almost describes my problem. The difference is that the nodeset I want the position within is dynamic, rather than a contiguous section of the document. To illustrate I'll modify the example from the linked question to match my requirements. Note that each <b> element is within a different <a> element. This is the critical bit. <root <a <bzyx</b </a <a <bwvu</b </a <a <btsr</b </a <a <bqpo</b </a </root Now if I queried, using XPath for a/b I'd get a nodeset of the four <b> nodes. I want to then find the position within that nodeset of the node that contains the string 'tsr'. The solution in the other post breaks down here: count(a/b[.='tsr']/preceding-sibling::*)+1 returns 1 because preceding-sibling is navigating the document rather than the context node-set. Is it possible to work within the context nodeset?

  • Navigating to nodes using xpath in flat structure

    - by James Berry
    I have an xml file in a flat structure. We do not control the format of this xml file, just have to deal with it. I've renamed the fields because they are highly domain specific and don't really make any difference to the problem. <attribute name="Title">Book A</attribute> <attribute name="Code">1</attribute> <attribute name="Author"> <value>James Berry</value> <value>John Smith</value> </attribute> <attribute name="Title">Book B</attribute> <attribute name="Code">2</attribute> <attribute name="Title">Book C</attribute> <attribute name="Code">3</attribute> <attribute name="Author"> <value>James Berry</value> </attribute> Key things to note: the file is not particularly hierarchical. Books are delimited by an occurance of an attribute element with name='Title'. But the name='Author' attribute node is optional. Is there a simple xpath statement I can use to find the authors of book 'n'? It is easy to identify the title of book 'n', but the authors value is optional. And you can't just take the following author because in the case of book 2, this would give the author for book 3. I have written a state machine to parse this as a series of elements, but I can't help thinking there would have been a way to directly get the results that I want.

  • Does XPath will return a object other than String

    - by Kalyan
    I have map xml as below. I can retrieve a value using XPath but can I retrieve object instead?. For example I want Map object to be retured if I say /list/* . Is it possible to retrieve as object. <list> <map> <val name="obj_type">USER</val> <val name="ret_name">user</val> <list name="attributes"> <map> <val name="obj_type">USER_ID</val> <val name="ret_name">userID</val> </map> <map> <val name="obj_type"> USER_UsernamePasswordCredential </val> <list name="attributes"> <map> <val name="obj_type">UNP_Username</val> <val name="ret_name">UserName</val> </map> <map> <val name="obj_type">UNP_Password</val> <val name="ret_name">Password</val> </map> </list> </map> </list> </map> </list>

  • Accessing the value of an input element with XPath in an XSLT

    - by asymmetric
    Hi! I'm developing a web app that has a button that triggers an XSLT transformation of the document DOM, with a stylesheet fetched via AJAX. Here's a portion of the HTML: <html> <head> <title>Static Javascript-based XMR Form Creator</title> </head> <body> <h1 id="title">Static Javascript-based XMR Form Creator</h1> <div class="opt_block" id="main_opts"> Form name <input type="text" id="form_name" /> Form cols <input type="text" id="form_cols" size="3" maxlength="3" /> </div> <button id="generate">Generate source</button> <textarea rows="20" cols="50" id="xmr_source" ></textarea> </body> Inside the stylesheet, I want to access the value attribute of the first input field, the one with id form_name. The XSLT looks like this: <xsl:template match="/html/body/div[@id = 'main_opts']" > <form> <xsl:attribute name="fname"> <xsl:value-of select="input[@id = 'form_name']/@value" /> </xsl:attribute> </form> </xsl:template> The problem is that the XPath that should do the work: <xsl:value-of select="input[@id = 'form_name']/@value" /> returns nothing. Can anyone help?

  • Need help with an xpath query!

    - by gerrod
    Can anyone help with the following XPath question? Given the node-set: <table> <rows> <row> <value column="Product">Coal</value> <value column="Quantity">10000</value> </row> <row> <value column="Product">Iron</value> <value column="Quantity">5000</value> </row> <row> <value column="Product">Ore</value> <value column="Quantity">4000</value> </row> </rows> </table> I want to query to find the node sub-set with a given product name. Note that the product name is being supplied by an attribute of the current node being processed (i.e. "@name"). So when the @name attribute has the value of "Coal" I would expect this to be returned: <row> <value column="Product">Coal</value> <value column="Quantity">10000</value> </row> This is what I've come up with; I know it's wrong, because I don't get anything back. $table/rows/row[value[@column='Product'][text()=@name]] </code>

  • XPath Query - Select relative top level nodes

    - by John
    I'm trying to iterate over some elements in an XML document that may be nested, but as I iterate over them I may be removing some from the tree. I'm thinking the best way is to do this recursively, so I'm trying to come up with an XPath Query that will select all the top-level nodes relative to the current node. //foo[not(ancestor::foo)] works great at the document level, but I'm trying to figure out how to do this from a relative query. <foo id="1"> <foo id="2" /> <foo id="3"> <foo id="4"> <bar> <foo id="5"> <foo id="6" /> </foo> <foo id="7" /> </bar> </foo> </foo> </foo> If the current node is foo#3, I only want to select foo#4. When the current node is foo#4, I only want to select foo#5 and foo#7. I think I'm trying to select any descendant foo nodes of the current node, but without any ancestor foo nodes between the current node and the node I'm selecting. My conundrum is if we're already inside a foo node, not(ancestor::foo) doesn't help.

  • Add two hexBinarys with XPATH 1.0

    - by fielding
    Hi, my xml document looks somewhat like that (Values are both xsl:hexBinary): <Offsets> <Offset> <Name>ErrorOffset</Name> <Value>DD</Value> </Offset> <Offset> <Name>OtherOffset</Name> <Value>FF</Value> </Offset> </Offsets> <Value> <Name>Error1</Name> <Code>01</Code> </Value> <Value> <Name>Error2</Name> <Code>02</Code> <Offset>ErrorOffset</Offset> </Value> now i want to transform this to a new xml file: <Value> <Name>Error1</Name> <Code>01</Code> </Value> <Value> <Name>Error2</Name> <Code>DF</Code> </Value> All that should happen is adding <Offset> to the basic <Value>. But plain + returns NaN and sum() expects only one parameter. XSLT and XPATH are quite nice, but it goes on my nerves that easy operations like adding two hex values just dont work as easy as it should.

  • xpath php attributes not working?

    - by Jared
    Getting this error Call to a member function attributes() on a non-object I have found multiple answers to this on SO, but none of them seem to solve my problem? Here is the XML: <Routes> <Route type="source" name="incoming"> </Route> <Routes> Here is the PHP: $doc = new SimpleXMLElement('routingConfig.xml', null, true); class traverseXML { function getData() { global $doc; $routeCount = count($doc -> xpath("Route")); //this value returns correctly $routeArr = array(); for ($i = 1; $i <= $routeCount; $i++) { $name = $doc -> Route[$i] -> attributes() -> name; array_push($routeArr, $name); } return $routeArr; } } $traverseXML = new traverseXML; var_dump($traverseXML -> getData()); I understand what the error means, but how is it a non-object? How do I return the name attribute of Routes/Route[1] ?

  • XPath select an attribute based on value

    - by Apeksha
    Using VB.Net, I have an XmlNode object, xNode. I need to select an attribute of this node if it has a particular value. e.g. xNode.SelectSingleNode(".[@attr1='1']") I would expect this statement to return the attribute "attr1", only if it has a value of "1". However, I get an error - Expression must evaluate to a node-set. When I tried this - xNode.SelectSingleNode("@attr1[@attr1='1']") It always returns Nothing, even if the attribute has a value of 1. I have tried a lot of different things, but no luck yet. Please help. Thanks.

  • Previewing php pages inside Expression Web 3 suddently stopped working

    - by user1660569
    On a Windows 7 development machine, I have expression web 3, PHP 5 installed I have been using expression web and PHP for a while, and previewing php pages etc on pressing F12 (preview using local server). Suddenly on F12 all PHP pages display as blank, even a phpinfo() file. Standard html pages continue to work correctly on F12. If I place the same page php inside the default website on inetpub and browse using localhost then the phpinfo() file works. So I know that php is installed and configured correctly for IIS. Things I've checked: Gone into site settings in Expression web and confirmed that php is selected and it is pointing to the php executable Reinstalled php Checked iis that the php extension is registered. Copied files to a different machine with expression web and php installed and it works on. The strange thing is that it gives a blank (no errors) page inside expression web, but does work inside inetpub This was working up until recently, then suddenly stopped for no reason.

  • Help needed wit the XPath statement for Selenium test

    I am testing a calendar component using selenium.In my test i want to click on the current date.Please help me with the XPath statement for doing that.I am adding the HTML for the calender component <input id="event_date" type="text" on="click then l:show.event.calendar" style="border: 1px solid rgb(187, 187, 187); width: 100px;" fieldset="new_event" decorator="redbox" validator="date"/> <img id="app_136" style="position: relative; top: 2px;" on="click then l:show.event.calendar" src="images/calendar.png"/> <div id="app_137" style="margin: 0pt; padding: 0pt;"> <div id="app_calendar_2" class="yui-calcontainer single withtitle" style="position: absolute; z-index: 1000;"> <div class="title">Select Event Date</div> <table id="app_calendar_2_cal" class="yui-calendar y2010" cellspacing="0"> <thead> <tr> </tr> <tr class="calweekdayrow"> <th class="calweekdaycell">Su</th> <th class="calweekdaycell">Mo</th> <th class="calweekdaycell">Tu</th> <th class="calweekdaycell">We</th> <th class="calweekdaycell">Th</th> <th class="calweekdaycell">Fr</th> <th class="calweekdaycell">Sa</th> </tr> </thead> <tbody class="m6 calbody"> <tr class="w22"> <td id="app_calendar_2_cal_cell0" class="calcell oom calcelltop calcellleft">30</td> <td id="app_calendar_2_cal_cell1" class="calcell oom calcelltop">31</td> <td id="app_calendar_2_cal_cell2" class="calcell wd2 d1 selectable calcelltop"> </td> <td id="app_calendar_2_cal_cell3" class="calcell wd3 d2 today selectable calcelltop selected"> <a class="selector" href="#">2</a> </td> I want to click the date component described in <td id="app_calendar_2_cal_cell3" class="calcell wd3 d2 today selectable calcelltop selected"> <a class="selector" href="#">2</a> </td> Thanks in advance mgeorge

  • Xpath expression to retrieve oldest/earliest node

    - by gkrogers
    I have an XML snippet, so: <STATES> <STATE> <NAME>Alabama</NAME> <ABBREVIATION>AL</ABBREVIATION> <CAPITAL>Montgomery</CAPITAL> <POPULATION>4661900</POPULATION> <AREA>52419</AREA> <DATEOFSTATEHOOD>14 December 1819</DATEOFSTATEHOOD> </STATE> <STATE> <NAME>Alaska</NAME> <ABBREVIATION>AK</ABBREVIATION> <CAPITAL>Juneau</CAPITAL> <POPULATION>698473</POPULATION> <AREA>663268</AREA> <DATEOFSTATEHOOD>1 January 1959</DATEOFSTATEHOOD> </STATE> <STATE> <NAME>Delaware</NAME> <ABBREVIATION>DE</ABBREVIATION> <CAPITAL>Dover</CAPITAL> <POPULATION>885122</POPULATION> <AREA>2490</AREA> <DATEOFSTATEHOOD>7 December 1787</DATEOFSTATEHOOD> </STATE> </STATES> <etc, etc.> I want to retrieve (for example) the capital of the oldest state (i.e. "Dover"). I have managed to get this far: //STATES/STATE[DATEOFSTATEHOOD='7 December 1787']/CAPITAL/text() but can't figure out how to say 'DATEOFSTATEHOOD={the earliest DATEOFSTATEHOOD}'. Can anybody point me in the right direction, please? SOLUTION: Matt's solution is more or less spot on. I had to reformat the dates (I used YYYYMMDDD) because, as was pointed out, Xpath 1.0 doesn't support the date format I was using. Also, Microsoft's XML library (4.0 and 6.0) returned the whole node list with Matt's expression. Reversing the test fixed that problem, making it return just the earliest node. So: //STATES/STATE[(DATEOFSTATEHOOD < //STATES/STATE/DATEOFSTATEHOOD)]/CAPITAL/text()

  • Is dynamic evaluation of xpath variable string possible using .net 2.0 xslt implementation?

    - by Crocked
    Hi, I'm trying to evaluate an xpath varable I'm building dynamically based on the position of the node. I can create the xpath string in a variable but when I select the value of this just get the string and not the node set I need. I use the following to create the xpath <xsl:variable name="xpathstring" select="normalize-space(concat(&quot;//anAttribute[@key='pos&quot;,position(),&quot;']&quot;))"/> and try to output the value with the following. <xsl:value-of select="$xpathstring"/> If I execute the xpath in my debugger I get the nodeset but in my xml output only get the xpath string which looks like this //anAttribute[@key='pos1'] I had a look at exslt dyn:evaluate which seems to enable this but this seems to be only supported by certain processors and doesn't provide a standalone implementation or at least as far as I could see (currently using the standard .net 2.0 xslt whihc is only xslt 1.0 as far as I recall) Is there anyway to handle this without changing processor? Kind Regards, Crocked

  • Selecting unique records in XSLT/XPath

    - by Daniel I-S
    I have to select only unique records from an XML document, in the context of an <xsl:for-each> loop. I am limited by Visual Studio to using XSL 1.0. <availList> <item> <schDate>2010-06-24</schDate> <schFrmTime>10:00:00</schFrmTime> <schToTime>13:00:00</schToTime> <variousOtherElements></variousOtherElements> </item> <item> <schDate>2010-06-24</schDate> <schFrmTime>10:00:00</schFrmTime> <schToTime>13:00:00</schToTime> <variousOtherElements></variousOtherElements> </item> <item> <schDate>2010-06-25</schDate> <schFrmTime>10:00:00</schFrmTime> <schToTime>12:00:00</schToTime> <variousOtherElements></variousOtherElements> </item> <item> <schDate>2010-06-26</schDate> <schFrmTime>13:00:00</schFrmTime> <schToTime>14:00:00</schToTime> <variousOtherElements></variousOtherElements> </item> <item> <schDate>2010-06-26</schDate> <schFrmTime>10:00:00</schFrmTime> <schToTime>12:00:00</schToTime> <variousOtherElements></variousOtherElements> </item> </availList> The uniqueness must be based on the value of the three child elements: schDate, schFrmTime and schToTime. If two item elements have the same values for all three child elements, they are duplicates. In the above XML, items one and two are duplicates. The rest are unique. As indicated above, each item contains other elements that we do not wish to include in the comparison. 'Uniqueness' should be a factor of those three elements, and those alone. I have attempted to accomplish this through the following: availList/item[not(schDate = preceding:: schDate and schFrmTime = preceding:: schFrmTime and schToTime = preceding:: schToTime)] The idea behind this is to select records where there is no preceding element with the same schDate, schFrmTime and schToTime. However, its output is missing the last item. This is because my XPath is actually excluding items where all of the child element values are matched within the entire preceding document. No single item matches all of the last item's child elements - but because each element's value is individually present in another item, the last item gets excluded. I could get the correct result by comparing all child values as a concatenated string to the same concatenated values for each preceding item. Does anybody know of a way I could do this?

  • Enhanced Dynamic Filtering

    - by Ricardo Peres
    Remember my last post on dynamic filtering? Well, this time I'm extending the code in order to allow two levels of querying: Match type, represented by the following options: public enum MatchType { StartsWith = 0, Contains = 1 } And word match: public enum WordMatch { AnyWord = 0, AllWords = 1, ExactPhrase = 2 } You can combine the two levels in order to achieve the following combinations: MatchType.StartsWith + WordMatch.AnyWord Matches any record that starts with any of the words specified MatchType.StartsWith + WordMatch.AllWords Not available: does not make sense, throws an exception MatchType.StartsWith + WordMatch.ExactPhrase Matches any record that starts with the exact specified phrase MatchType.Contains + WordMatch.AnyWord Matches any record that contains any of the specified words MatchType.Contains + WordMatch.AllWords Matches any record that contains all of the specified words MatchType.Contains + WordMatch.ExactPhrase Matches any record that contains the exact specified phrase Here is the code: public static IList Search(IQueryable query, Type entityType, String dataTextField, String phrase, MatchType matchType, WordMatch wordMatch, Int32 maxCount) { String [] terms = phrase.Split(' ').Distinct().ToArray(); StringBuilder result = new StringBuilder(); PropertyInfo displayProperty = entityType.GetProperty(dataTextField); IList searchList = null; MethodInfo orderByMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "OrderBy").ToArray() [ 0 ].MakeGenericMethod(entityType, displayProperty.PropertyType); MethodInfo takeMethod = typeof(Queryable).GetMethod("Take", BindingFlags.Public | BindingFlags.Static).MakeGenericMethod(entityType); MethodInfo whereMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "Where").ToArray() [ 0 ].MakeGenericMethod(entityType); MethodInfo distinctMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "Distinct" && m.GetParameters().Length == 1).Single().MakeGenericMethod(entityType); MethodInfo toListMethod = typeof(Enumerable).GetMethod("ToList", BindingFlags.Static | BindingFlags.Public).MakeGenericMethod(entityType); MethodInfo matchMethod = typeof(String).GetMethod ( (matchType == MatchType.StartsWith) ? "StartsWith" : "Contains", new Type [] { typeof(String) } ); MemberExpression member = Expression.MakeMemberAccess ( Expression.Parameter(entityType, "n"), displayProperty ); MethodCallExpression call = null; LambdaExpression where = null; LambdaExpression orderBy = Expression.Lambda ( member, member.Expression as ParameterExpression ); switch (matchType) { case MatchType.StartsWith: switch (wordMatch) { case WordMatch.AnyWord: call = Expression.Call ( member, matchMethod, Expression.Constant(terms [ 0 ]) ); where = Expression.Lambda ( call, member.Expression as ParameterExpression ); for (Int32 i = 1; i ()); where = Expression.Lambda ( Expression.Or ( where.Body, exp ), where.Parameters.ToArray() ); } break; case WordMatch.ExactPhrase: call = Expression.Call ( member, matchMethod, Expression.Constant(phrase) ); where = Expression.Lambda ( call, member.Expression as ParameterExpression ); break; case WordMatch.AllWords: throw (new Exception("The match type StartsWith is not supported with word match AllWords")); } break; case MatchType.Contains: switch (wordMatch) { case WordMatch.AnyWord: call = Expression.Call ( member, matchMethod, Expression.Constant(terms [ 0 ]) ); where = Expression.Lambda ( call, member.Expression as ParameterExpression ); for (Int32 i = 1; i ()); where = Expression.Lambda ( Expression.Or ( where.Body, exp ), where.Parameters.ToArray() ); } break; case WordMatch.ExactPhrase: call = Expression.Call ( member, matchMethod, Expression.Constant(phrase) ); where = Expression.Lambda ( call, member.Expression as ParameterExpression ); break; case WordMatch.AllWords: call = Expression.Call ( member, matchMethod, Expression.Constant(terms [ 0 ]) ); where = Expression.Lambda ( call, member.Expression as ParameterExpression ); for (Int32 i = 1; i ()); where = Expression.Lambda ( Expression.AndAlso ( where.Body, exp ), where.Parameters.ToArray() ); } break; } break; } query = orderByMethod.Invoke(null, new Object [] { query, orderBy }) as IQueryable; query = whereMethod.Invoke(null, new Object [] { query, where }) as IQueryable; if (maxCount != 0) { query = takeMethod.Invoke(null, new Object [] { query, maxCount }) as IQueryable; } searchList = toListMethod.Invoke(null, new Object [] { query }) as IList; return (searchList); } And this is how you'd use it: IQueryable query = ctx.MyEntities; IList list = Search(query, typeof(MyEntity), "Name", "Ricardo Peres", MatchType.Contains, WordMatch.ExactPhrase, 10 /*0 for all*/); SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

  • XSL apply templates not working...could be XPath error

    - by AdRock
    I have converted mny stylesheet to use apply templates instead of call templates and it worked fine for my other styesheet, which was more complicated, but this one doesn't seem to work even thought it is a much simpler template. All that it outputs is the sex node and the userlevel node. I think it has to do with my Xpath. All i want is to output the < user information, nothing else <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template name="hoo" match="/"> <html> <head> <title>Registered Members</title> <link rel="stylesheet" type="text/css" href="user.css" /> </head> <body> <h1>Registered Members</h1> <xsl:for-each select="folktask/member/user"> <div class="userdiv"> <xsl:apply-templates/> </div> </xsl:for-each> </body> </html> </xsl:template> <xsl:template match="folktask/member/user"> <xsl:apply-templates select="@id"/> <xsl:apply-templates select="personal/name"/> <xsl:apply-templates select="personal/address1"/> <xsl:apply-templates select="personal/city"/> <xsl:apply-templates select="personal/county"/> <xsl:apply-templates select="personal/postcode"/> <xsl:apply-templates select="personal/telephone"/> <xsl:apply-templates select="personal/mobile"/> <xsl:apply-templates select="personal/email"/> <xsl:apply-templates select="personal"/> <xsl:apply-templates select="account/username"/> <xsl:apply-templates select="account"/> </xsl:template> <xsl:template match="@id"> <div class="heading bold"><h2>USER ID: <xsl:value-of select="." /></h2></div> </xsl:template> <xsl:template match="personal/name"> <div class="small bold">NAME:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/address1"> <div class="small bold">ADDRESS:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/city"> <div class="small bold">CITY:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/county"> <div class="small bold">COUNTY:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/postcode"> <div class="small bold">POSTCODE:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/telephone"> <div class="small bold">TELEPHONE:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/mobile"> <div class="small bold">MOBILE:</div> <div class="large"><xsl:value-of select="." /> </div> </xsl:template> <xsl:template match="personal/email"> <div class="small bold">EMAIL:</div> <div class="large"> <xsl:element name="a"> <xsl:attribute name="href"> <xsl:text>mailto:</xsl:text> <xsl:value-of select="." /> </xsl:attribute> <xsl:value-of select="." /> </xsl:element> </div> </xsl:template> <xsl:template match="personal"> <div class="small bold">SEX:</div> <div class="colored bold"> <xsl:choose> <xsl:when test="sex='Male'"> <div class="sex male"><xsl:value-of select="sex/."/></div> </xsl:when> <xsl:otherwise> <div class="sex female"><xsl:value-of select="sex/."/></div> </xsl:otherwise> </xsl:choose> </div> </xsl:template> <xsl:template match="account/username"> <div class="small bold">USERNAME:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="account"> <div class="small bold">ACCOUNT TYPE:</div> <div class="colored "> <xsl:choose> <xsl:when test="userlevel='1'"> <div class="nml bold">Normal User</div> </xsl:when> <xsl:when test="userlevel='2'"> <div class="vol bold">Volunteer</div> </xsl:when> <xsl:when test="userlevel='3'"> <div class="org bold">Organiser</div> </xsl:when> <xsl:otherwise> <div class="name adm bold">Administrator</div> </xsl:otherwise> </xsl:choose> </div> </xsl:template> </xsl:stylesheet> and some of my xml <?xml version="1.0" encoding="ISO-8859-1" ?> <?xml-stylesheet type="text/xsl" href="users.xsl"?> <folktask xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:noNamespaceSchemaLocation="folktask.xsd"> <member> <user id="1"> <personal> <name>Abbie Hunt</name> <sex>Female</sex> <address1>108 Access Road</address1> <address2></address2> <city>Wells</city> <county>Somerset</county> <postcode>BA5 8GH</postcode> <telephone>01528927616</telephone> <mobile>07085252492</mobile> <email>[email protected]</email> </personal> <account> <username>AdRock</username> <password>269eb625e2f0cf6fae9a29434c12a89f</password> <userlevel>4</userlevel> <signupdate>2010-03-26T09:23:50</signupdate> </account> </user> <volunteer id="1"> <roles></roles> <region>South West</region> </volunteer> </member> <member> <user id="2"> <personal> <name>Aidan Harris</name> <sex>Male</sex> <address1>103 Aiken Street</address1> <address2></address2> <city>Chichester</city> <county>Sussex</county> <postcode>PO19 4DS</postcode> <telephone>01905149894</telephone> <mobile>07784467941</mobile> <email>[email protected]</email> </personal> <account> <username>AmbientExpert</username> <password>8e64214160e9dd14ae2a6d9f700004a6</password> <userlevel>2</userlevel> <signupdate>2010-03-26T09:23:50</signupdate> </account> </user> <volunteer id="2"> <roles>Van Driver,gas Fitter</roles> <region>South Central</region> </volunteer> </member> </folktask>

  • C# Open Source software that is useful for learning Design Patterns

    - by Fathom Savvy
    In college I took a class in Expert Systems. The language the book taught (CLIPS) was esoteric - Expert Systems: Principles and Programming, Fourth Edition. I remember having a tough time with it. So, after almost failing the class, I needed to create the most awesome Expert System for my final presentation. I chose to create an expert system that would calculate risk analysis for a person's retirement portfolio. In short, the system would provide the services normally performed by one's financial adviser. In other words, based on personality, age, state of the macro economy, and other factors, should one's portfolio be conservative, moderate, or aggressive? In the appendix of the book (or on the CD-ROM), there was this in-depth example program for something unrelated to my presentation. Over my break, I read and re-read every line of that program until I understood it to the letter. Even though it was unrelated, I learned more than I ever could by reading all of the chapters. My presentation turned out to be pretty damn good and I received praises from my professor and classmates. So, the moral of the story is..., by understanding other people's code, you can gain greater insight into a language/paradigm than by reading canonical examples. Still, to this day, I am having trouble with everyday design patterns such as the Factory Pattern. I would like to know if anyone could recommend open source software that would help me understand the Gang of Four design patterns, at the very least. I have read the books, but I'm having trouble writing code for the concepts in the real world. Perhaps, by studying code used in today's real world applications, it might just "click". I realize a piece of software may only implement one kind of design pattern. But, if the pattern is an implementation you think is good for learning, and you know what pattern to look for within the source, I'm hoping you can tell me about it. For example, the System.Linq.Expressions namespace has a good example of the Visitor Pattern. The client calls Expression.Accept(new ExpressionVisitor()), which calls ExpressionVisitor (VisitExtension), which calls back to Expression (VisitChildren), which then calls Expression (Accept) again - wooah, kinda convoluted. The point to note here is that VisitChildren is a virtual method. Both Expression and those classes derived from Expression can implement the VisitChildren method any way they want. This means that one type of Expression can run code that is completely different from another type of derived Expression, even though the ExpressionVisitor class is the same in the Accept method. (As a side note Expression.Accept is also virtual). In the end, the code provides a real world example that you won't get in any book because it's kinda confusing. To summarize, If you know of any open source software that uses a design pattern implementation you were impressed by, please list it here. I'm sure it will help many others besides just me. public class VisitorPatternTest { public void Main() { Expression normalExpr = new Expression(); normalExpr.Accept(new ExpressionVisitor()); Expression binExpr = new BinaryExpression(); binExpr.Accept(new ExpressionVisitor()); } } public class Expression { protected internal virtual Expression Accept(ExpressionVisitor visitor) { return visitor.VisitExtension(this); } protected internal virtual Expression VisitChildren(ExpressionVisitor visitor) { if (!this.CanReduce) { throw Error.MustBeReducible(); } return visitor.Visit(this.ReduceAndCheck()); } public virtual Expression Visit(Expression node) { if (node != null) { return node.Accept(this); } return null; } public Expression ReduceAndCheck() { if (!this.CanReduce) { throw Error.MustBeReducible(); } Expression expression = this.Reduce(); if ((expression == null) || (expression == this)) { throw Error.MustReduceToDifferent(); } if (!TypeUtils.AreReferenceAssignable(this.Type, expression.Type)) { throw Error.ReducedNotCompatible(); } return expression; } } public class BinaryExpression : Expression { protected internal override Expression Accept(ExpressionVisitor visitor) { return visitor.VisitBinary(this); } protected internal override Expression VisitChildren(ExpressionVisitor visitor) { return CreateDummyExpression(); } protected internal Expression CreateDummyExpression() { Expression dummy = new Expression(); return dummy; } } public class ExpressionVisitor { public virtual Expression Visit(Expression node) { if (node != null) { return node.Accept(this); } return null; } protected internal virtual Expression VisitExtension(Expression node) { return node.VisitChildren(this); } protected internal virtual Expression VisitBinary(BinaryExpression node) { return ValidateBinary(node, node.Update(this.Visit(node.Left), this.VisitAndConvert<LambdaExpression>(node.Conversion, "VisitBinary"), this.Visit(node.Right))); } }

  • Regular Expression Transformation

    The regular expression transformation exposes the power of regular expression matching within the pipeline. One or more columns can be selected, and for each column an individual expression can be applied. The way multiple columns are handled can be set on the options page. The AND option means all columns must match, whilst the OR option means only one column has to match. If rows pass their tests then rows are passed down the successful match output. Rows that fail are directed down the alternate output. This transformation is ideal for validating data through the use of regular expressions. You can enter any expression you like, or select a pre-configured expression within the editor. You can expand the list of pre-configured expressions yourself. These are stored in a Xml file, %ProgramFiles%\Microsoft SQL Server\nnn\DTS\PipelineComponents\RegExTransform.xml, where nnn represents the folder version, 90 for 2005, 100 for 2008 and 110 for 2012. If you want to use regular expressions to manipulate data, rather than just validating it, try the RegexClean Transformation. The component is provided as an MSI file, however for 2005/200 you will have to add the transformation to the Visual Studio toolbox by hand. This process has been described in detail in the related FAQ entry for How do I install a task or transform component?, just select Regular Expression Transformation in the Choose Toolbox Items window. Downloads The Regular Expression Transformation is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed.
