Redirect problem: Stack Overflow error
Hi everybody,
first post ... please be patient.
I am having trouble using the "redirect" extension element
on my own style sheets. I did the sample 1-redir.xml
which worked fine, but I get a StackOverflow error when
transforming a document of my own (both stylesheet and
sample document are attached at the end of this post). As
you can see the stylesheet is moderately recursive, but
not at all at this point. So the StackOverflowError must
have its cause somewhere else.
thanks in advance for any help, and Happy New Year!
cheers,
Jakob.
