Re: [xsl] Count() elements in range

["M. David Peterson" <conners_dad@xxxxxxx>]

Chris,

At first glance I noticed you have following-sibling wrapped in parentheses. 
The only time you will use parentheses is when you are invoking a function. 
In this case you are just searching for a particular node using a standard 
XPath expression.

So, this...

<xsl:when test="(following-sibling::element[1][child::flag]) or
> (count(following-sibling::element) = 0)">

should read like this...

<xsl:when test="following-sibling::element[1][child::flag] | 
count(following-sibling::element) = 0)">

Im rushing out the door and don't have time to look to see what other issues 
you might have or what solutions would work best but if I get back and this 
hasn't helped or someone else hasn't been able to help I will take another 
look at it.

Best regards,

M.
