[xsl] Global location path confusion

[Jonas Eschenburg <indyjo@xxxxxx>]

Hi everybody!

XSLT is quite new to me so please forgive me if this is a stupid question.

I have the following XSLT stylesheet:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="1.0">

 <xsl:template match="doc">
  <doc>
    <xsl:apply-templates/>
  </doc>
 </xsl:template>

 <xsl:template match="a">
  <x title="{/doc/@title}"/>
 </xsl:template>

 <xsl:template match="b">
  <xsl:param name="content">
    <a/>
  </xsl:param>
  <xsl:apply-templates select="$content"/>
 </xsl:template>
 
</xsl:stylesheet>

Then I feed it the following xml:

<?xml version="1.0" encoding="iso-8859-1"?>

<doc title="abc">
 <a/>
 <b/>
</doc>

This results in the following output xml:

<doc>
 <x title="abc"></x>
 <x title=""></x>
</doc>

My question:
Why does the second "abc" get eaten up?
Why doesn't it result in this?

<doc>
 <x title="abc"></x>
 <x title="abc"></x>
</doc>

I tried this with xalan-c as well as saxon.
