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"/>
~ </Document>
</Documents>
So perhaps it's a bug in msxml 4.0, as Michael suggested.

| 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.
