Formatting hyperlinks and paragraphs

7/9/2003

xsl-list,

In  a  perfect  world the stylesheet code below will take text from an
xml  element,  and:

1)  transform  text  that begins with 'http' into hyperlinks 2) format
the output to preserve line breaks.

At  the  moment  the code successfully formats the hyperlinks, but not
line breaks. Hopefully someone can point out my error?

Regards,

Pete
