  • Fastest way to parse XML files in C#?

    - by LifeH2O
    I have to load many XML files from internet. But for testing with better speed i downloaded all of them (more than 500 files) of the following format. <player-profile> <personal-information> <id>36</id> <fullname>Adam Gilchrist</fullname> <majorteam>Australia</majorteam> <nickname>Gilchrist</nickname> <shortName>A Gilchrist</shortName> <dateofbirth>Nov 14, 1971</dateofbirth> <battingstyle>Left-hand bat</battingstyle> <bowlingstyle>Right-arm offbreak</bowlingstyle> <role>Wicket-Keeper</role> <teams-played-for>Western Australia, New South Wales, ICC World XI, Deccan Chargers, Australia</teams-played-for> <iplteam>Deccan Chargers</iplteam> </personal-information> <batting-statistics> <odi-stats> <matchtype>ODI</matchtype> <matches>287</matches> <innings>279</innings> <notouts>11</notouts> <runsscored>9619</runsscored> <highestscore>172</highestscore> <ballstaken>9922</ballstaken> <sixes>149</sixes> <fours>1000+</fours> <ducks>0</ducks> <fifties>55</fifties> <catches>417</catches> <stumpings>55</stumpings> <hundreds>16</hundreds> <strikerate>96.95</strikerate> <average>35.89</average> </odi-stats> <test-stats> . . . </test-stats> <t20-stats> . . . </t20-stats> <ipl-stats> . . . </ipl-stats> </batting-statistics> <bowling-statistics> <odi-stats> . . . </odi-stats> <test-stats> . . . </test-stats> <t20-stats> . . . </t20-stats> <ipl-stats> . . . </ipl-stats> </bowling-statistics> </player-profile> I am using XmlNodeList list = _document.SelectNodes("/player-profile/batting-statistics/odi-stats"); And then loop this list with foreach as foreach (XmlNode stats in list) { _btMatchType = GetInnerString(stats, "matchtype"); //it returns null string if node not availible . . . . _btAvg = Convert.ToDouble(stats["average"].InnerText); } Even i am loading all files offline, parsing is very slow Is there any good faster way to parse them?

  • get xml attribute named xlink:href using xsl

    - by awe
    How can I get the value of an attribute called xlink:href of an xml node in xsl template?

  • Switching languajes on a website with PHP

    - by jnkrois
    Hello everybody, I'm just looking for some advice. I'm creating a website that offers (at least) 2 languages. The way I'm setting it up is by using XML files for the language, PHP to retrieve the values in the XML nodes. Say you have any XML file, being loaded as follows: <?php $lang = "en"; $xmlFile = simplexml_load_file("$lang/main.xml"); ?> Once the file contents are available, I just output each node into an HTML tag like so: <li><?php echo $xmlFile->navigation->home; ?></li> which in turn is equal to : <li><a href="#">Home</a></li> as a nav bar link. Now, the way in which I'm switching languages is by changing the value of the "$lang" variable, through a "$_POST", like so: if(isset($_POST['es'])){ $lang = "es"; }elseif(isset($_POST['en'])){ $lang = "en"; } The value of the "$lang" variable is reset and the new file is loaded, loading as well all the new nodes from the new XML file, hence changing the language. I'm just wondering if there is another way to reset the "$lang" variable using something else, other than "$_POST" or "$_GET". I don't want to use query string either. I know I could use JavaScript or jQuery to achieve this, but I'd like to make the site not too dependable on JavaScript. I'd appreciate any ideas or advice. Thanks

  • how to get entire document in scrapy using hxs.select

    - by Chris Smith
    I've been at this for 12hrs and I'm hoping someone can give me a leg up. Here is my code all I want is to get the anchor and url of every link on a page as it crawls along. from scrapy.contrib.spiders import CrawlSpider, Rule from scrapy.contrib.linkextractors.sgml import SgmlLinkExtractor from scrapy.selector import HtmlXPathSelector from scrapy.utils.url import urljoin_rfc from scrapy.utils.response import get_base_url from urlparse import urljoin #from scrapy.item import Item from tutorial.items import DmozItem class HopitaloneSpider(CrawlSpider): name = 'dmoz' allowed_domains = ['domain.co.uk'] start_urls = [ 'http://www.domain.co.uk' ] rules = ( #Rule(SgmlLinkExtractor(allow='>example\.org', )), Rule(SgmlLinkExtractor(allow=('\w+$', )), callback='parse_item', follow=True), ) user_agent = 'Mozilla/5.0 (Windows; U; MSIE 9.0; WIndows NT 9.0; en-US))' def parse_item(self, response): #self.log('Hi, this is an item page! %s' % response.url) hxs = HtmlXPathSelector(response) #print response.url sites = hxs.select('//html') #item = DmozItem() items = [] for site in sites: item = DmozItem() item['title'] = site.select('a/text()').extract() item['link'] = site.select('a/@href').extract() items.append(item) return items What I'm doing wrong... my eyes hurt now.

  • Scrapy Not Returning Additonal Info from Scraped Link in Item via Request Callback

    - by zoonosis
    Basically the code below scrapes the first 5 items of a table. One of the fields is another href and clicking on that href provides more info which I want to collect and add to the original item. So parse is supposed to pass the semi populated item to parse_next_page which then scrapes the next bit and should return the completed item back to parse Running the code below only returns the info collected in parse If I change the return items to return request I get a completed item with all 3 "things" but I only get 1 of the rows, not all 5. Im sure its something simple, I just can't see it. class ThingSpider(BaseSpider): name = "thing" allowed_domains = ["somepage.com"] start_urls = [ "http://www.somepage.com" ] def parse(self, response): hxs = HtmlXPathSelector(response) items = [] for x in range (1,6): item = ScrapyItem() str_selector = '//tr[@name="row{0}"]'.format(x) item['thing1'] = hxs.select(str_selector")]/a/text()').extract() item['thing2'] = hxs.select(str_selector")]/a/@href').extract() print 'hello' request = Request("www.nextpage.com", callback=self.parse_next_page,meta={'item':item}) print 'hello2' request.meta['item'] = item items.append(item) return items def parse_next_page(self, response): print 'stuff' hxs = HtmlXPathSelector(response) item = response.meta['item'] item['thing3'] = hxs.select('//div/ul/li[1]/span[2]/text()').extract() return item

  • Does an XPathDocument load the whole xml document?

    - by Wires
    If I do XPathDocument doc = new XPathDocument("filename.xml"); Does that load the entire document into memory? I'm writing a mobile phone app and the document might store lots of data that doesn't ever need to all be loaded at the same time. Mobile phones don't usually have too much ram!

  • XDocument change all attribute names

    - by Dested
    I have an XDocument that looks similar to <root> <a> <b foo="1" bar="2" /> <b foo="3" bar="4" /> <b foo="5" bar="6" /> <b foo="7" bar="8" /> <b foo="9" bar="10" /> </a> </root> I wish to change the attribute foo to something else, and the attribute bar to something else. How can I easily do this? My current version (below) stack overflows with large documents, and has an awful smell to it. string dd=LoadedXDocument.ToString(); foreach (var s in AttributeReplacements) dd = dd.Replace(s.Old+"=", s.New+"=");

  • Using XSLT to Find Nodes Given a Set of Parameters

    - by davecardwell
    Sorry about the title—wasn’t sure how to word it. Basically I have some XML like this: <countries> <country handle="bangladesh"/> <country handle="india"/> <country handle="pakistan"/> </countries> And some XSLT like this (which doesn’t work): <xsl:template match="/countries"> <xsl:param name="popular"/> <xsl:apply-templates select="country[count($popular/country[@handle = current()/@handle]) &gt; 0]" /> </xsl:template> <xsl:template match="/countries/country"> … </xsl:template> I want to pass in a list of popular destinations like this: <popular> <country handle="india"/> <country handle="pakistan"/> </popular> …to the /countries template and have it only operate on the ones in the $popular param. At the moment this simply does nothing. Changing the selector to country[true()] operates on them all, so at least I know the basic structure is right. Any ideas? I think I may be getting confused by what is currently “current()”.

  • XSL - How to match consecutive comma-separated tags

    - by PocketLogic
    I'm trying to match a series of xml tags that are comma separated, and to then apply an xslt transformation on the whole group of nodes plus text. For example, given the following partial XML: <p>Some text here <xref id="1">1</xref>, <xref id="2">2</xref>, <xref id="3">3</xref>. </p> I would like to end up with: <p>Some text here <sup>1,2,3</sup>.</p> A much messier alternate would also be acceptable at this point: <p>Some text here <sup>1</sup><sup>,</sup><sup>2</sup><sup>,</sup><sup>3</sup>.</p> I have the transformation to go from a single xref to a sup: <xsl:template match="xref""> <sup><xsl:apply-templates/></sup> </xsl:template> But I'm at a loss as to how to match a group of nodes separated by commas. Thanks.

  • updating multiple nodes in xml with xquery and xdmp:node-replace

    - by morja
    Hi all, I wnat to update an XML document in my xml database (Marklogic). I have xml as input and want to replace each node that exists in the target xml. If a node does not exist it would be great if it gets added, but thats maybe another task. My XML in the database: <user> <username>username</username> <firstname>firstname</firstname> <lastname>lastname</lastname> <email>[email protected]</email> <comment>comment</comment> </user> The value of $user_xml: <user> <firstname>new firstname</firstname> <lastname>new lastname</lastname> </user> My function so far: declare function update-user ( $username as xs:string, $user_xml as node()) as empty-sequence() { let $uri := user-uri($username) return for $node in $user_xml/user return xdmp:node-replace(fn:doc($uri)/user/fn:node-name($node), $node) }; First of all I cannot iterate over $user_xml/user. If I try to iterate over $user_xml I get "arg1 is not of type node()" exception. But maybe its the wrong approach anyway? Does anybody maybe have sample code how to do this?

  • Trying to use RemoveChild() on XmlNodeList messes up my XmlNode collection

    - by user299090
    Hi there, I'm trying to remove a specific node from a XmlNodeList named listaWidths. This specific list has 5 items before I use RemoveChild(). But, after the RemoveChild() statement, the list stays only with 1 item. XmlNodeList listaWidths = xmlDoc.SelectNodes("/MsBuild:Report/MsBuild:Body/MsBuild:ReportItems/MsBuild:Tablix/MsBuild:TablixBody/MsBuild:TablixColumns/*", nsmgr); int indexEpoca = 0; //Remover época XmlNode node = listaWidths[indexEpoca]; XmlNode parent = listaWidths[indexEpoca].ParentNode; parent.RemoveChild(node); This is a RDL Reporting Services XML. The specific XML code is here: <Tablix Name="Tablix3"> <TablixBody> <TablixColumns> <TablixColumn> <Width>1.602in</Width> </TablixColumn> <TablixColumn> <Width>1.61in</Width> </TablixColumn> <TablixColumn> <Width>1.6323in</Width> </TablixColumn> <TablixColumn> <Width>1.6023in</Width> </TablixColumn> <TablixColumn> <Width>1.6033in</Width> </TablixColumn> </TablixColumns> (...)

  • Display different xsl:attribute depending on the ending of a string

    - by Johann
    Dear All, I have the following xsl code in an xsl document <A target="_blank" style="text-decoration=none"> <xsl:attribute name="href">viewdoc.aspx?doc=<xsl:value-of select="URLFilePath"/>&amp;mode=inline</xsl:attribute> <xsl:attribute name="prefix"><xsl:value-of select="FileName"/>: </xsl:attribute> <IMG src="images/word_small.gif" border="0"/> </A> and in the code-behind I am doing this newItemNode = xmlDocument.CreateElement("URLFilePath") newItemNode.InnerText = correctedPath xmlItemNode.ParentNode.AppendChild(newItemNode) Now that works fine for word documents. However I need a way in code to check the extension of the file, and display the correct Image and xsl:attribute depending on the If statement. So the If statement will be like this:- If correctedPath.ToLower.Contains(".doc") Then //display the word icon and attributes Else //display the excel icon and attributes End If Can you please give me some tips and help on how I can achieve this? Thanks

  • A case-insensitive related implementation problem

    - by Robert
    Hi All, I am going through a final refinement posted by the client, which needs me to do a case-insesitive query. I will basically walk through how this simple program works. First of all, in my Java class, I did a fairly simple webpage parsing: title=(String)results.get("title"); doc = docBuilder.parse("http://" + server + ":" + port + "/exist/rest/db/wb/xql/media_lookup.xql?" + "&title=" + title); This Java statement references an XQuery file "media_lookup.xql" which is stored on localhost, and the only parameter we are passing is the string "title". Secondly, let's take at look at that XQuery file: $title := request:get-parameter('title',""), $mediaNodes := doc('/db/wb/portfolio/media_data.xml'), $query := $mediaNodes//media[contains(title,$title)], Then it will evaluate that query. This XQuery will get the "title" parameter that are passes from our Java class, and query the "media_data" xml file stored in the database, which contains a bunch of media nodes with a 'title' element node. As you may expect, this simple query will just match those media nodes whose 'title' element contains a substring of what the value of string 'title' is. So if our 'title' is "Chi", it will return media nodes whose title may be "Chicago" or "Chicken". The refinment request posted by the client is that there should be NO case-sensitivity. The very intuitive way is to modify the XQuery statement by using a lower-case funtion in it, like: $query := $mediaNodes//media[contains(lower-case(title/text(),lower-case($title))], However, the question comes: this modified query will run my machine into memory overflow. Since my "media_data.xml" is quite huge and contains thouands of millions of media nodes, I assume the lower-case() function will run on each of the entries, thus causing the machine to crash. I've talked with some experienced XQuery programmer, and they think I should use an index to solve this problem, and I will definitely research into that. But before that, I am just posting this problem here to get other ideas or any suggestions, do you think any other way may help? for example, could I tweak the Java parse statement to realize the case-insensitivity? Since I think I saw some people did some string concatination by using "contains." in Java before passing it to the server. Any idea or help is welcomed, thanks in advance.
