hi group,

I have a problem with understanding why a transform of my stopped working. I found a solution, but I am not sure what the right way to solve it is.

I made a simplified example to show the problem. Input file:

<doc>
<p><Char>hello</Char><Char> there</Char></p>
</doc>

I started with a stylesheet like this, in which I process content twice, in the normal way (stylesheet is input document as well):


<?xml version="1.0" encoding="UTF-8"?>
<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs xsl">


<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes" />

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

  <xsl:template match="p">
    <xsl:variable name='blip'>
      <xsl:apply-templates />
    </xsl:variable>

    <xsl:apply-templates select='$blip' mode='pass2' />
  </xsl:template>

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

  <xsl:template match='char' mode='#all'>
    <c><xsl:apply-templates /></c>
  </xsl:template>
</xsl:transform>

In pass 1 the Char elements are renamed to char, in pass2 the char elements are renamed to c. Simple and works. The (expected) output is

<?xml version="1.0" encoding="utf-8"?>
<document xmlns="http://www.w3.org/1999/xhtml">
   <c>hello</c>
   <c> there</c>
</document>

However, it stops to work when I add a default namespace:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:transform version="2.0"
        xmlns="http://www.w3.org/1999/xhtml"
			xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                        xmlns:xs="http://www.w3.org/2001/XMLSchema"
                        exclude-result-prefixes="xs xsl">
  <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes" />

etcetera.

The char-match-template now does not fire and the result is

<?xml version="1.0" encoding="utf-8"?>
<document xmlns="http://www.w3.org/1999/xhtml">
  hello there
</document>

Presumably, the document node in de variable inherits the new default namespace. What is the best way to fix this? I got it working again changing the match on "char" to "*:char" but there must be better ways.

regards, Ruud
