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.
