Re: [xsl] conditional multiple outputs

[Michael Müller-Hillebrand <mmh@xxxxxxxxxxxxx>]

As almost always, the error message is correct.

You basically loop through all <title> in document order and try to
create a new document for each <title>. So the second time you see a
title with "file 1" your XSL tries to create another file1.xml - boom!

Try it the other way round:

<xsl:result-document href="file1.xml">
  <xsl:for-each select="title[starts-with(., 'file 1')]">
    <xsl:copy-of select="."/>
  </
</
<xsl:result-document href="file2.xml">
  <xsl:for-each select="title[starts-with(., 'file 2')]">
    <xsl:copy-of select="."/>
  </
</
<xsl:result-document href="file3.xml">
  <xsl:for-each select="title[starts-with(., 'file 3')]">
    <xsl:copy-of select="."/>
  </
</
