  • Finding Line Beginning using Regular expression in Notepad++

    - by Michel Merlin
    Finding Line Beginning using Regular expression in Notepad++ (Sorry if this is a newbie question) I want to strip a 4000-line HTML file from all the jQuery "done" stuff, e.g.: <DIV class=menu done27="1" done26="0" done9="1" done8="0" done7="1" done6="0" done4="20"> should be replaced with: <DIV class=menu> In http://www.zytrax.com/tech/web/regex.htm#experiment I can do it with RE: [ ^]done[0-9]+="[0-9]+" but in Notepad++ 5.6.8 UNICODE, in a .HTM file encoded in ANSI, Search Find, Search mode = Regular expression, putting this RE in the "Find what" field won't work (it will only find the 5 occurrences starting with a space, it will miss the 2 occurrences starting at the beginning of a line; IOW, the caret for line beginning, or the alternating it with a space, fails). How do I? TIA, Versailles, Wed 21 Apr 2010 10:42:20 +0200

  • PHP: Regular Expression to get a URL from a string

    - by Matthew Iselin
    I'm working on some PHP code which takes input from various sources and needs to find the URLs and save them somewhere. The kind of input that needs to be handled is as follows: http://www.youtube.com/watch?v=IY2j_GPIqRA Try google: http://google.com! (note exclamation mark is not part of the URL) Is http://somesite.com/ down for anyone else? Output: http://www.youtube.com/watch?v=IY2j_GPIqRA http://google.com http://somesite.com/ I've already borrowed one regular expression from the internet which works, but unfortunately wipes the query string out - not good! Any help putting together a regular expression, or perhaps another solution to this problem, would be appreciated.

  • Examining a lambda expression at runtime in C#

    - by Ben Aston
    I have a method Get on a type MyType1 accepting a Func<MyType2, bool> as a parameter. An example of its use: mytype1Instance.Get(x => x.Guid == guid)); I would like create a stub implementation of the method Get that examines the incoming lambda expression and determines what the value of guid is. Clearly the lambda could be "anything", but I'm happy for the stub to make an assumption about the lambda, that it is trying to match on the Guid property. How can I do this? I suspect it involves the use of the built-in Expression type?

  • AIR SQLite IN expression not working

    - by goseta
    Hi, I'm having a problem with an expression in my sql statement in SQLite for Adobe AIR basically I have this sql = "UPDATE uniforms SET status=@status WHERE customerId IN(19,20)"; updateStmt.parameters["@status"] = args[1]; updateStmt.execute(); if I run the above code it works, updating the status when the id are 19 and 20 but if I pass the ids list as a parameter like this sql = "UPDATE uniforms SET status=@status WHERE customerId IN(@ids)"; updateStmt.parameters["@status"] = args[1]; updateStmt.parameters["@ids"] = "19,20"; updateStmt.execute(); it gives me and error, saying could not convert text value to numeric value, which make sense because I'm passing and string but the IN expression should convert it accordingly, like it does when I pass directly the list values, why is not working the other way, thanks for any help!

  • Erroneous Matches with Regular Expression

    - by Ballsacian1
    $regexp = '/(?:<input\stype="hidden"\sname="){1}([a-zA-Z0-9]*)(?:"\svalue="1"\s\/>)/'; $response = '<input type="hidden" name="7d37dddd0eb2c85b8d394ef36b35f54f" value="1" />'; preg_match($regexp, $response, $matches); echo $matches[1]; // Outputs: 7d37dddd0eb2c85b8d394ef36b35f54f So I'm using this regular expression to search for an authentication token on a webpage implementing Joomla in order to preform a scripted login. I've got all this working but am wondering what is wrong with my regular expression as it always returns 2 items. Array ( [0] => [1] => 7d37dddd0eb2c85b8d394ef36b35f54f) Also the name of the input I'm checking for changes every page load both in length and name.

  • Regular Expression for accurate word-count using JavaScript

    - by Haidon
    I'm trying to put together a regular expression for a JavaScript command that accurately counts the number of words in a textarea. One solution I had found is as follows: document.querySelector("#wordcount").innerHTML = document.querySelector("#editor").value.split(/\b\w+\b/).length -1; But this doesn't count any non-Latin characters (eg: Cyrillic, Hangul, etc); it skips over them completely. Another one I put together: document.querySelector("#wordcount").innerHTML = document.querySelector("#editor").value.split(/\s+/g).length -1; But this doesn't count accurately unless the document ends in a space character. If a space character is appended to the value being counted it counts 1 word even with an empty document. Furthermore, if the document begins with a space character an extraneous word is counted. Is there a regular expression I can put into this command that counts the words accurately, regardless of input method?

  • How can I get a Node adjacent to a unique Node using Scala?

    - by pr1001
    I'm trying to parse an Apple plist file and I need to get an array Node within it. Unfortunately its only unique identifier is sibling Node right before it, <key>ProvisionedDevices</key>. Right now my best thoughts are to use Java's XPATH querying or Node.indexOf. Here is an example: <plist version="1.0"> <dict> <key>ApplicationIdentifierPrefix</key> <array> <string>RP8CBF4MRE</string> </array> <key>CreationDate</key> <date>2010-05-10T11:44:35Z</date> <key>DeveloperCertificates</key> <array> ... <key>ProvisionedDevices</key> <array> ... // I need the Nodes here </array> </dict> </plist> Thanks!

  • Regular expression for a string containing one word but not another

    - by Chris Stahl
    I'm setting up some goals in Google Analytics and could use a little regex help. Lets say I have 4 URLs http://www.anydotcom.com/test/search.cfm?metric=blah&selector=size&value=1 http://www.anydotcom.com/test/search.cfm?metric=blah2&selector=style&value=1 http://www.anydotcom.com/test/search.cfm?metric=blah3&selector=size&value=1 http://www.anydotcom.com/test/details.cfm?metric=blah&selector=size&value=1 I want to create an expression that will identify any URL that contains the string selector=size but does NOT contain details.cfm I know that to find a string that does NOT contain another string I can use this expression: (^((?!details.cfm).)*$) But, I'm not sure how to add in the selector=size portion. Any help would be greatly appreciated!

  • Qt/C++ regular expression library with unicode property support

    - by Dave
    I'm converting an application from the .Net framework to Qt using C++. The application makes extensive use of regular expression unicode properties, i.e. \p{L}, \p{M}, etc. I've just discovered that the QRegExp class lacks support for this among other things (lookbehinds, etc.) Can anyone recommend a C++ regular expression library that: Supports unicode properties Is unicode-aware in other respects (i.e. \w matches more than ASCII word characters) As a bonus, supports lookbehinds. Please don't point me to the wikipedia article; I don't trust it. That article says that QRegExp supports unicode properties. Unless I'm really doing something wrong, it doesn't. I'm looking for someone actually using unicode properties with a regex library in a project.

  • Generate a Constant expression from a function

    - by Lee
    For my Google Wave robot, on the onDocumentChanged event I want to apply a filter as follows: @Capability(filter = FILTER) @Override public void onDocumentChanged(DocumentChangedEvent event) { ... } I want the filter to be generated the first time the robot is run, which I'm trying to do as follows: private static final String FILTER = generateFilter(); private static final String generateFilter(){ ... } However, it complains FILTER isn't a constant expression when used within @Capability. generateFilter() will return the same string every time it is called, I'm only using it to create the string so that when I make changes, I don't need to worry about updating the filter. Now I could be going about this all wrong, so wondered if anyone knew what I'm doing wrong, or knew a better way in which I could generate a constant expression from the function.

  • Regular Expression

    - by equilibrium
    Ohh! this regular expression thing is eating my brain up. I have been reading it from Introduction to Automata Theory, Languages and Computer by Hopcroft, Motwani and Ullman. I have solved a few exercises too but could not solve the following even after trying for almost one hr. The problem is to write a regular expression that defines a language consisting of all strings of 0s and 1s except the substring 011. Is the answer (0+1)* - 011 correct ? If not what should be the correct answer for this?

  • Regular expression one or more times JAVA

    - by user1381564
    Hi i am trying to match a string against a pattern this is the possible string signal CS, NS, dl: stateType := writeOrRead0; signal CS, pS : stateType := writeOrRead0; signal dS : stateType := writeOrRead0; i am only concerned with the pattern as far as the first colon. but the number of signals define can be more than one it could be three or four even this is the regular expression i have ^signal\\s*(\\w+),*\\s*(\\w+)\\s*: it will pick up the second two signal but and for the second one it picks up CS and pS and but the d and S in the next signal when i use matcher.group() come up seperately Can anyone give me an expression that will pick up all signal names whether there is one two three or more?

  • Why does a non-constant offsetof expression work?

    - by Chris J. Kiick
    Why does this work: #include <sys/types.h> #include <stdio.h> #include <stddef.h> typedef struct x { int a; int b[128]; } x_t; int function(int i) { size_t a; a = offsetof(x_t, b[i]); return a; } int main(int argc, char **argv) { printf("%d\n", function(atoi(argv[1]))); } If I remember the definition of offsetof correctly, it's a compile time construct. Using 'i' as the array index results in a non-constant expression. I don't understand how the compiler can evaluate the expression at compile time. Why isn't this flagged as an error?

  • Succinct LINQ to XML Query

    - by Kent Boogaart
    Assuming you have the following XML: <?xml version="1.0" encoding="utf-8"?> <content> <info> <media> <image> <info> <imageType>product</imageType> </info> <imagedata fileref="http://www.example.com/image1.jpg" /> </image> <image> <info> <imageType>manufacturer</imageType> </info> <imagedata fileref="http://www.example.com/image2.jpg" /> </image> </media> </info> </content> Using LINQ to XML, what is the most succinct, robust way to obtain a System.Uri for an image of a given type? At the moment I have this: private static Uri GetImageUri(XElement xml, string imageType) { return (from imageTypeElement in xml.Descendants("imageType") where imageTypeElement.Value == imageType && imageTypeElement.Parent != null && imageTypeElement.Parent.Parent != null from imageDataElement in imageTypeElement.Parent.Parent.Descendants("imagedata") let fileRefAttribute = imageDataElement.Attribute("fileref") where fileRefAttribute != null && !string.IsNullOrEmpty(fileRefAttribute.Value) select new Uri(fileRefAttribute.Value)).FirstOrDefault(); } This works, but feels way too complicated. Especially when you consider the XPath equivalent. Can anyone point out a better way?

  • Lambda expression will not compile

    - by John Soer
    I am very confused. I have this lamba expression: tvPatientPrecriptionsEntities.Sort((p1, p2) => p1.MedicationStartDate .Value .CompareTo(p2.MedicationStartDate.Value)); Visual Studio will not compile it and complains about syntax. I converted the lamba expression to an anonymous delegate as so: tvPatientPrecriptionsEntities.Sort( delegate(PatientPrecriptionsEntity p1, PatientPrecriptionsEntity p2) { return p1.MedicationStartDate .Value .CompareTo(p2.MedicationStartDate.Value); }); and it works fine. The project uses .NET 3.5 and I have a reference to System.Linq.

  • Tentative date casting in tsql

    - by Tewr
    I am looking for something like TRYCAST in TSQL or an equivalent method / hack. In my case I am extracting some date data from an xml column. The following query throws "Arithmetic overflow error converting expression to data type datetime." if the piece of data found in the xml cannot be converted to datetime (in this specific case, the date is "0001-01-01" in some cases). Is there a way to detect this exception before it occurs? select [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'datetime') FROM Customers An example of what I am trying to achieve in pseudocode with an imagined tsql function TRYCAST(expr, totype, defaultvalue): select TRYCAST( [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'nvarchar(100)'), datetime, null) FROM Customers

  • Are there any good Java/JVM libraries for my Expression Tree architecture?

    - by Snuggy
    My team and I are developing an enterprise-level application and I have devised an architecture for it that's best described as an "Expression Tree". The basic idea is that the leaf nodes of the tree are very simple expressions (perhaps simple values or strings). Nodes closer to the trunk will get more and more complex, taking the simpler nodes as their inputs and returning more complex results for their parents. Looking at it the other way, the application performs some task, and for this it creates a root expression. The root expression divides its input into smaller units and creates child expressions, which when evaluated it can use to build it's own result. The subdividing process continues until the simplest leaf nodes. There are two very important aspects of this architecture: It must be possible to manipulate nodes of the tree after it is built. The nodes may be given new input values to work with and any change in result for that node needs to be propagated back up the tree to the root node. The application must make best use of available processors and ultimately be scalable to other computers in a grid or in the cloud. Nodes in the tree will often be updating concurrently and notifying other interested nodes in the tree when they get a new value. Unfortunately, I'm not at liberty to discuss my actual application, but to aid understanding a little bit, you might imagine a kind of spreadsheet application being implemented with a similar architecture, where changes to cells in the table are propagated all over the place to other cells that need the result. The spreadsheet could get so massive that applying multi-core multi-computer distributed system to solve it would be of benefit. I've got my prototype "Expression Engine" working nicely on a single multi-core PC but I've started to run into a few concurrency issues (as expected because I haven't been taking too much care so far) so it's now time to start thinking about migrating the Engine to a more robust library, and that leads to a number of related questions: Is there any precedent for my "Expression Tree" architecture that I could research? What programming concepts should I consider. I realise this approach has many similarities to a functional programming style, and I'm already aware of the concepts of using futures and actors. Are there any others? Are there any languages or libraries that I should study? This question is inspired by my accidental discovery of Scala and the Akka library (which has good support for Actors, Futures, Distributed workloads etc.) and I'm wondering if there is anything else I should be looking at as well?

  • Parsing Web Service Response in Oracle 9i

    - by zechariahs
    I'm having trouble parsing an XML response from a web service. I have a feeling this is due to a namespace issue. But, after 4 hours of research, trial-and-error, and head-banging I haven't been able to resolve it. Please help. My goal is to get a dbms_xmldom.DOMNodeList that contains "ERRORS" nodes.

  • How to limit results in a SharePoint XSL query

    - by David
    Hello all, I am creating a SharePoint site that we will use to report issues with trucks used in our business. Linked to the list I have created will be a page that will display an overview of the trucks and a little truck icon will show the trucks current status. Green and the truck is okay (no open issues), Red and the truck have an open issue with status "Undrivable", Orange and there is two issues open that requires the user to look further into the truck before using it and finally a Gray truck for when there is a new issue created that has not been looked into (not sure if it is drivable or not). I have managed to create the "Dashboard" and with my limit XSL/XPATH knowledge been able to add a truck and replicate the description above but... in my test I have created 4 issues, for example if three of them are changed to status Closed and one left to Undrivable I will get four icons on the page, three with Green trucks and the last one Red. So in theory it works but I obviously only want to see the last truck, one truck. I am not interested in seeing the others. <xsl:template name="dvt_1.rowview"> <xsl:variable name="CountReport" select="count(/dsQueryResponse/Rows/Row[@Highloader='GGEU12' and @Status!='Closed'])" /> <xsl:variable name="MoreThan" select="$CountReport &gt; 1" /> <xsl:variable name="NoReports" select="$CountReport = 0" /> <xsl:variable name="Closed" select=" @Highloader='GGEU12' and @Status='Closed'" /> <xsl:choose> <xsl:when test="$MoreThan"> <div class="ms-vb"><img title='More than one report exist!' border='0' alt='In Progress' src='highloader/Library/hl-orange.png' /></div> </xsl:when> <xsl:otherwise> <div class="ms-vb"><xsl:value-of disable-output-escaping="yes" select="@Icon" /></div> </xsl:otherwise> </xsl:choose> </xsl:template> My hope is that someone with slightly more knowledge can find the last piece of the puzzle for me! Thanks for reading and asking questions to fill any gap I left above. David
