Re: Position of a Child


Frank,

What you mean by "position of that child inside the context node" is 
actually a bit problematic, possibly meaning any of a number of things. How 
to get it depends both on what you mean, and what your input data looks like.

For starters, you could try 
(count(*[name()=$NodeName]/preceding-sibling::*) + 1) -- that is, 1 + the 
number of the node's preceding element siblings. If you have mixed content 
(and thus the siblings you want to count include text nodes), or if there's 
some other wrinkle (such as more than one child node being named 
$NodeName), come back.

position() isn't very useful because it returns the position of the context 
node within the current node list, which isn't what you want. You could 
make it be what you want by doing something like:

<xsl:for-each select="*">
   <xsl:if test="name()=$NodeName">
     <xsl:value-of select="."/>
     <xsl:value-of select="position()"/>
   </xsl:if>
</xsl:for-each>

But again, I'm making assumptions about what you really want -- and you can 
see this is more roundabout than simple counting the preceding siblings.

Cheers,
Wendell
