Re: Node position and numbering.

<p>1. Go to File menu<br/>
2. Select Print<br/>
3. Click Print</p>

Tested with Saxon 8.

Note that

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="service">
    <p>
      <xsl:apply-templates select="step"/>
    </p>
  </xsl:template>

  <xsl:template match="step">
    <xsl:number/><xsl:text>. </xsl:text><xsl:value-of select="."/><xsl:if 
test="not(position() = last())"><br/></xsl:if>
  </xsl:template>

</xsl:stylesheet>

produced exactly the same result (without processing the nodes other than 
step nodes).

You don't have to account for every child node to use apply-templates.

Re:  Node position and numbering.






Spencer,

Thats what I trying to explain in my email.  That,
very unfortunately, I cannot do apply-templates on
<step> nodes.  The biggest reason for not able to do
that is that I could have 100+ different possible
child nodes within <service> node and each child node
could potentially appear in any order.  So I cannot do
apply-templates on specific child nodes as I would NOT
know what order I need to it in and second I'd have to
do 100 apply-templates for each child node.

I know its not the best XML design but heck thats what
I am handed down and I have to make it work.  Not my
choice.

Thx,
C.
