Hi Anton,
Here's the XSL stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:key name="by-info" match="Article" use="@info"/>
<xsl:param name="filter" select="'food'"></xsl:param>
<xsl:template match="Documents">
<!-- @filter='' will be true if it is there and empty or if it is not
there at all) -->
<xsl:apply-templates select="*[(_at_)filter='' or
@filter=$filter]"/>
<Documents>
<xsl:for-each select="Document[(_at_)filter='' or
@filter=$filter]/Article[count(.|key('by-info',@info)[(_at_)filter='' or
@filter=$filter][1])=1]">
<Document name="{(_at_)info}">
<xsl:copy-of
select="key('by-info',@info)[(_at_)filter=$filter]"/>
</Document>
</xsl:for-each>
</Documents>
</xsl:template>
</xsl:stylesheet>
The line proposed by David C. gives an exception.
<xsl:for-each select="Document[(_at_)filter='' or
@filter=$filter]/Article[count(.|key('by-info',@info)[(_at_)filter='' or
@filter=$filter][1])=1]">
The XML looks like:
<?xml version="1.0" encoding="utf-8"?>
<Documents>
<Document chapter="1" title="title 1" href="file1.xml" filter="">
<Article title="1.1" info="sub" filter="drink"/>
<Article title="1.2" info="main" filter="food"/>
</Document>
<Document chapter="2" title="title 2" href="file2.xml" filter="drink">
<Article title="2.1" info="sub" filter="drink"/>
<Article title="2.2" info="main" filter="food"/>
</Document>
</Documents>
Thanx.

Hi Michael (I'm jumping in again, was away yesterday)
did you define the key in this template? (that caused the exception last
time, didn't it)
if so, maybe you'll better post the complete stylesheet once more... (+
exception details)
Anton
