xsl number value

Your problem is simply that xsl:number works differently from what you expect: in particular, the 'value' attribute doesn't work this way.

It may seem to be a bit of a kluge, but unfortunately to get the correct number you want using xsl:number, you have to change the context node to the node that you want to count. This can be readily done with a new template:

 <xsl:template match="//see">
    'see' finds destination '<xsl:value-of select="id(@ref)"/>',
    whose position is: <xsl:apply-templates select="id(@ref)" mode="number"/>.

 <xsl:template match="*" mode="number">

If you're too lazy to make a new template, you could put the whole thing in a for-each.

Another alternative would be to skip the xsl:number altogether and use a simple count, as in:

<xsl:template match="//see">
'see' finds destination '<xsl:value-of select="id(@ref)"/>',
whose position is: <xsl:value-of select="count(id(@ref)/preceding-sibling::*)+1"/>.

Of course this will only work if you want the simplest of numbering schemes.

I'm using ID referencing. Accessing the children of a
referenced node works fine with XT, but an xsl:number
element using the reference returns always zero. Is
something wrong with my code?

Here's an example:

<!DOCTYPE myroot [
  <!ELEMENT see (#PCDATA)>
  <!ELEMENT dest (#PCDATA)>
  <!ATTLIST dest id ID #REQUIRED> ]>
  <see ref="D2"/>
  <dest id="D1">Node D1</dest>
  <dest id="D2">Node D2</dest>
  <dest id="D3">Node D3</dest>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version
  <xsl:template match="//see">
    'see' finds destination '<xsl:value-of select="id(@ref)"/>',
    whose position is: <xsl:number value="id(@ref)"/>.
  <xsl:template match="text()"/>

'see' finds destination 'Node D2',
whose position is: 0.
