I want to return a value from a template(getIdList). The returned
value is saved in a variable ($idList) and is a string wich is the
concatenation of my nodes id : id1,id2,id3,...
I use this code wich is not working... i got nothing when i display
the variable value...!!
Here's my code:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:output indent="yes" method="html" omit-xml-declaration="no"
encoding="ISO-8859-1" />
<xsl:param name="delimiter" select="','"/>
<xsl:template match="/root">
<xsl:variable name="idList">
<xsl:call-template select="/root/vid" name="getIdList" />
</xsl:variable>
<xsl:value-of select="$idList"/>
</xsl:template>
<xsl:template match="/root/vid" name="getIdList">
<xsl:for-each select=".">
<xsl:variable name="var"
select="concat($var,ids, $delimiter)"/>
</xsl:for-each>
<xsl:value-of select="$var"/>
</xsl:template>
</xsl:stylesheet>
What's wrong in it? is there another simple way to get what i want?

Hi Dave,
for the first, you cannot pass parameters to a template with select and
match.
The other problem is the scope of the variable 'var'. It only lives
within the scope of the for-each. So if you try to get a value from it
outside the foreach it is empty (it is not defined)
See the stylesheet below for a newbie-solution. It uses recursion.
