Fun with CDATA.

[Raber Chris <cp...@yahoo.com>]

This is probably better asked to an XSLT forum, but
here goes. I am doing WEB clipping/transcoding using
jTidy & Xalan.

Source html gets fed into jTidy, resulting XHTML gets
fed into Xalan with a style sheet that does the web
clipping.

One of the challanges is handling script code. What I
did is enhance (hack) jTidy to wrap script code in
CDATA. This works fine unless the scipt code is also
wrapped in comments. Consider this block:

<script type="text/javascript" language="JavaScript">
<![CDATA[
<!-- 
var remote = null;
function rs(n,u,w,h) {
  remote = window.open(u, n, 'width=' + w + ',height='
+ h +',resizable=yes,scrollbars=no');
  if (remote != null) {
    if (remote.opener == null)
      remote.opener = self;
    window.name = 'yilff';
    remote.location.href = u;
  }
}
function clickHandler(url)
{window.open(url,'mediaframe_window','toolbar=no,width=750,height=550,left=0,top=30,status=no,scrollbars=no,resizable=yes');}
//-->
]]>
</script>

When this is run through XSLT with an "identity copy"
template, the output is:

<script type="text/javascript" language="JavaScript"
xml:space="preserve">

&lt;!-- 
var remote = null;
function rs(n,u,w,h) {
  remote = window.open(u, n, 'width=' + w + ',height='
+ h +',resizable=yes,scrollbars=no');
  if (remote != null) {
    if (remote.opener == null)
      remote.opener = self;
    window.name = 'yilff';
    remote.location.href = u;
  }
}
function clickHandler(url)
{window.open(url,'mediaframe_window','toolbar=no,width=750,height=550,left=0,top=30,status=no,scrollbars=no,resizable=yes');}
//--&gt;

</script>

And the browser shows an error on the line where the
'<' in the comment has been changed to &lt;.

Any suggestions on how to get CDATA to output < and >
instead of &lt; and &gt; here? Or maybe a better
approach?

TIA,

-Chris.
