Re: conditional multiple outputs

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!

<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="."/>
  </
</

Hi,

I am trying to generate multiple output files in a single template
(see
xsl file below). The scenario is the following:

1. I read elements <title> one after the other from a input file
"content.xml"
2. if the text of the element <title> begins with the substring
"file 1",
then copy the element to the output file file1.xml, if it begins with
"file 2" then output to file2.xml, else copy the element to file3.xml.

The processor I use is Saxon B on .NET and XLST version is 2.0. But my
script does not work since I always have following error message:

E:\test\xsl>Transform -s:"e:\test\xsl\content.xml"
-xsl:"e:\test\xsl\import.xsl
Error at xsl:choose on line 8 of file:///e:/test/xsl/import.xsl:
 XTDE1490: Cannot write more than one result document to the same
URI, or
write to a URI
 that has been read: file:/E:/test/xsl/file2.xml
Transformation failed: Run-time errors were reported

Here are the script and the input file content.xml:

<!--content.xml-->
<?xml version="1.0" encoding="UTF-8"?>
<groups>
       <group>
               <title>file 1 xxx </title>
               <title>file 2 efg </title>
       </group>
       <group>
               <title>file 2 xxx </title>
               <title>file 3 abc </title>
       </group>
       <group>
               <title>file 1 abc </title>
               <title>file 3 xyz </title>
       </group>
       <group>
               <title>file 2 zzz </title>
               <title>file 2 ihk </title>
       </group>
</groups>

                                                       </
contentOfTitleElmt>
                                               </xsl:result-document>
                                       </xsl:otherwise>
                               </xsl:choose>
                       </xsl:for-each>
               </xsl:for-each>
       </xsl:template>
</xsl:stylesheet>

Does somebody know why it does not work? Should I use another function
than xsl:result-document?

Many thanks in advance,
Regards

Horace
