Re: count following-sibling node()‏

 *My earlier post got moderated by Hotmail as it did not consider XML
as  legitimate text*
 I am sure people made some sence of my mail but this is what I meant..

 Calling node() is not the same as calling the Element itself
Node in Xpath means:
 element, attribute, text, namespace, processing-instruction, comment,
and document (root) nodes.

 This is the tricky bit you should be careful about when you are using
the position() function or calculating the following sibling etc..

 Your logic will *Fail*  if there are other elements , or text nodes etc..

 the easiest way to explain your problem is to introduce another
element after your sixth EVENT , call it
 *NEW-EVENT*
 <xsl:value-of select="count(following-sibling::EVENT)"/> will call
ONLY EVENT nodes
 <xsl:value-of select="count(following-sibling::node())"/> WILL CALL
even the NEW-EVENT nodes




 This is easy identification of problem.


 It gets tricky when there are invisible nodes like the text nodes.

 <xsl:value-of select="count(following-sibling::EVENT)"/> will call
ONLY EVENT nodes
 When
 <xsl:value-of select="count(following-sibling::node())"/> WILL CALL
*ALL* the nodes including the invisible text nodes.

 Its really not *invisible* text nodes for a pair of eyes seeing XML
for a long time. But it could be confusing!!

 I think this is where you got confused.
