xsltproc, XMLSpy's internal processor and msxml 3.0 yield the following
result (differing only in whitespace) using the files in your last mail:
<Documents>
~  <Document name="sub"/>
~  <Document name="main">
~    <Article title="1.2" info="main" filter="food"/>
~    <Article title="2.2" info="main" filter="food"/>

| 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="*[@filter='' or @filter=$filter]"/>
|
|             <Documents>
|                  <xsl:for-each select="Document[@filter='' or
| @filter=$filter]/Article[count(.|key('by-info',@info)[@filter='' or
| @filter=$filter][1])=1]">
|                     <Document name="{@info}">
|                          <xsl:copy-of
| select="key('by-info',@info)[@filter=$filter]"/>
|                     </Document>
|                   </xsl:for-each>
|             </Documents>
|
|         </xsl:template>
|
| </xsl:stylesheet>
|
|
| The line proposed by David C. gives an exception.
|
| <xsl:for-each select="Document[@filter='' or
| @filter=$filter]/Article[count(.|key('by-info',@info)[@filter='' or
| @filter=$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.
