Hi All,

I would like to get all the content/text in

node from the XML document where

has a child node <strong>Interest:<strong>. Below is the listing of both XML document and XSLT stylesheet:

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE html (View Source for full doctype...)> - <html xmlns="http://www.w3.org/1999/xhtml" xmlns:html="http://www.w3.org/1999/xhtml"> - <head> - <body ....... - ><div id="container"> + <div id="header"> <div id="postmark" /> - <div id="content"> + <div id="as1"> ....... <h1>Employee Detail</h1> - <p> <strong>Interest:</strong> <br /> Tennis <br /> Movie <br /> Swimming <br /> ..... <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns="http://www.w3.org/1999/xhtml" exclude-result-prefixes="ns"> <xsl:template match="/"> <area> - <xsl:for-each select="/ns:html/ns:body/ns:div[@id='content']/ns:p/ns:strong"> - <xsl:if test="contains(.,'Interest:')"> - <xsl:choose> - <xsl:when test="contains(.,'Interest:')"> - <interest> <xsl:value-of select="../text()" /> </interest> </xsl:when> - <xsl:otherwise> <interest>Unknown</interest> </xsl:otherwise> </xsl:choose> </xsl:if> </xsl:template> </xsl:stylesheet> The transformation process produces the following output: <?xml version="1.0" encoding="UTF-8"?> <html xmlns="http://www.w3.org/1999/xhtml"> <title>Employee Detail</title> <body> <h1>Employee Detail</h1> <interest>Tennis</interest> </body> </title> </html>
One possible solution is by using recursion to go through the list of values on nodes but I am cannot think of how this could be done. Perhaps my difficulty is that I don’t know how to navigate down the list of interest of the same node using xsl command. Most of the Googled articles consisted of searching for the same type of element a cross multiple nodes, where as I am looking all the values (same type anyway) in a single node.

Below is the JDOM XPath solution to get the same list of values: XPath interestxpath = XPath.newInstance("/ns:html/ns:body/ns:div[@id='content']/ns:p[10]/node()"); interestxpath.addNamespace("ns", "http://www.w3.org/1999/xhtml"); java.util.List interest_list = interestxpath.selectNodes(employeejdomDocument); Iterator interest_iterator = interest_list.iterator(); while (interest_iterator.hasNext()) { interest_value = ((org.jdom.Content)interest_iterator.next()).getValue(); ……
I am new to XSLT stylesheet transformation and can do with some guidances.

Many thanks again,

Jack

Would you turn that thing down? I'm controlling a mind here! Look ... look at the tiny ad ...
