Hi,
I'm a FOP/XSL newbie, so please spell out any response. Thanks.
My problem is that I want to produce a PDF document from some XML. I'm using
FOP to do this and the problem I have may be XSL related, so my apologies if
this is the wrong forum to use. If an XSL forum is the place to go could you
please advise which one. I've already tried Dev Shed with no luck.
There may also be a better way for me to solve this problem, I'm sure !
My XML can contain optional attributes for tables, things like border-width,
border-style etc. I need to supply default values if the attribute does not
exist and as there could be many optional parameters I don't want to use
XSL:choose statements to cope with the variations.
Instead I'm trying to use a get_params template to see what parameter is in
question, return the value of the supplied attribute else the default which
is then used in a with_params statement. The code below is a cludge to try
and get it working for one attribute (border-style) only.
With the xml & code below I get the following error (from FOP) at the marked
location:
xsl:with-param is not allowed in this position in the stylesheet!
XML
