problems with xpath and matching templates

Gero MeiÃner · August 15th, 2003, 06:15 AM

THE TEMPLATES:

<xsl:template match="article">
<xsl:apply-templates select="title"/>
</xsl:template>

<xsl:template match="article[position()=1]">
<xsl:apply-templates select="title"/>
</xsl:template>

<xsl:template match="article[position()=1]/title">
<xsl:text>Title#1</xsl:text>
</xsl:template>

<xsl:template match="article[position()>1]/title">
<xsl:text>Title#x</xsl:text>
</xsl:template>

THE DOCUMENT:
<document>
<article><title>Title#1</title></article>
<article><title>Title#2</title></article>
</document>

THE PROBLEM:
The template for 'title' for the first(!) 'article' doesn't match. I use libxslt 10032.
Can anyone tell me whether the templates are wrong or if there is a bug in libxslt?

Thank you very much!

The templates you supplied have a drawback: check the "match" attribute for the 3-rd and 4-th templates; the quotation mark(") is missing. Try to correct this and then test the code, it should do what you intended.

Sorry!!! I added the quotation marks. The original templates contain the quotation marks and caused the problem I described. So the problem is not a syntax error.

Ok. I tried to test the code with Saxon 6.5.2 with the following stuff:

XML source document:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<document>
    <article>
        <title>Title#1</title>
    </article>
    <article>
        <title>Title#2</title>
    </article>
    <article>
        <title>Title#3</title>
    </article>
</document>

XSL stylesheet:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="article">
      <xsl:apply-templates select="title"/>
    </xsl:template>

    <xsl:template match="article[position()=1]">
      <xsl:apply-templates select="title"/>
    </xsl:template>

    <xsl:template match="article[position()=1]/title">
      <xsl:text>Title#1</xsl:text>
    </xsl:template>

    <xsl:template match="article[position()>1]/title">
      <xsl:text>Title#x</xsl:text>
    </xsl:template>
</xsl:stylesheet>

and got the following output:

Code:

    Title#1
    Title#x
    Title#x

That is, it's working fine.

Try to test exactly the same code with the same source doc. It's interesting: what will be the output with libxslt 10032? May be you need to add a template rule for the document root(/)? Although built-in template is applied when it's not there, but in any case try to put also the template rule for document root.
