Different behaviour when using last()

[Anders Samuelson <an...@aspiro.com>]

Hi,

I have the following template snippet:

<xsl:template match="paragraph">
			<xsl:apply-templates/>
		  <xsl:if test="child::node()[position()=last()]=text()">
      	  <xsl:call-template name="br"/>
        </xsl:if>
</xsl:template>

The purpose is that the 'br' template should only be called if the last child node of the paragraph element is a text node.
This wok fine with Microsoft XML Parser 3.0 but not with xalan 2.0.0 (or 2.3.0 fo that matter).
With xalan the test argument is always true (as far as i can tell from my tests).

Has anyone got a clue how I can get this to work?
Any help is greatly appriciated!

BR,

Anders Samuelson

I haven't tested, but you might try:

child::node()[self::* or string-length(normalize-space(.)) > 0]
[position()=last()][self::text()]

I'm guessing that if you have an element at the end of your paragraph, you 
probably have whitespace after that element.  The child::node() axis would 
also return the text node representing that space, and so the last node is 
always a text node.  So the first predicate makes it so that 
[position()=last()] is only applied on elements or text nodes that have 
non-whitespace.

If you've already accounted for all that, then, well, I'm at a loss for 
ideas. :)

It's also probably better to use self::text() instead of "=text()", since the 
'=' sign is used to compare *all* of the child nodes matching text(), instead 
of just one; self::text() is probably more efficient.
