[Thread Next] Re: Is it possible to modify a source node using XSLT?To: NULL Date: 5/6/2005 3:35:00 AM Thanks for the response! You have answered my question about modifying the source very well. I will try to post my XSLT code tomorrow when I get to work. It will probably help explain what I am trying to do. thanks, B David Carlisle wrote: > Barry Andrews <titanandrews@n...> writes: > > >>Hi, >> >> So the source is read only?
