Hi Michael,
Below is the output from your helpful suggestion:
( 1 ) <area>
( 2 ) <interest>Tennis</interest>
( 3 ) <interest>Movie</interest>
( 4 ) <interest>Swimming</interest>
( 5 ) </area>
( a ) <xsl:stylesheet version="1.0"
( b ) xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
( c ) xmlns:ns="http://www.w3.org/1999/xhtml"
( d ) exclude-result-prefixes="ns">
( e )
( g )<area>
( h )<xsl:apply-templates select="//ns:p"/>
( i ) </area>
( j )</xsl:template>
( k )<xsl:template match="ns:p[ns:strong='Nearest Hotels:']">
( l ) <xsl:for-each select="text()[normalize-space() != '']">
( m )<nearest_hotels><xsl:value-of select="normalize-space()"/></nearest_hotels>
( n ) </xsl:for-each>
( o ) </xsl:template>
( p )<xsl:template match="ns:p"/>
( q )
( r )</xsl:stylesheet>
This is the closest thing to what I wanted except that I would it to co-exist with the existing working XSL statements:
( i ) I could not getting another list of element values (e.g. favourite songs...) that comes immediately after the <Interest> element. This may be due to the context node having been changed by when running the aboved stylesheet.
( ii ) There are other element values that I need to retrieve from the same document, where some is made up of a single value while others may have multiple occurrences. I will need to some how include the aboved code segment into the following existing working stylesheet responsible for retrieving other single element values, using the current context node where possible:
<xsl:template match="/">
<area>
<xsl:for-each select="/ns:html/ns:body/ns:div[@id='content']/ns:p/ns:strong">
<xsl:if test="contains(.,'Firstname:')">
<xsl:choose>
<xsl:when test="contains(.,'Firstname:')">
<firstname><xsl:value-of select="../ns:a"/></firstname>
</xsl:when>
<xsl:otherwise>
<firstname>Unknown</firstname>
</xsl:otherwise>
</xsl:choose>
</xsl:if>
<xsl:if test="contains(.,'Surname:')">
<xsl:choose>
<xsl:when test="contains(.,'Surname:')">
<surname><xsl:value-of select="../text()"/></surname>
</xsl:when>
<xsl:otherwise>
<surname>Unknown</surname>
</xsl:otherwise>
</xsl:choose>
......
Thank you so much for the on-going guidances,
Jack

Subject: [xml-dev] XSLT stylesheet looping through the same node (recursion?)Hi All,
I would like to get all the content/text in <p> node from the XML document where <p> 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
