Enable JS Compression within CDATA

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Include Javascript with CDATA in HTML Document (Style 2, see coming text)
2. Compress HTML Document with Html Compressor
3. Javascript is not compressed

What version of the product are you using? 0.9


Hi there,

according to the W3C xHTML Specification (http://www.w3.org/TR/xhtml1/ ,
section 4.8) Javascript should be put into cdata to validate successfully:

<script type="text/javascript">
<![CDATA[
... unescaped script content ...
]]>
</script>

To avoid confusing older browsers the cdata tags are often put into
comments like:
Style 1:
<script type="text/javascript">
/* <![CDATA[ */
  ... unescaped script content ...
/* ]]> */
</script>

or
Style2:
<script type="text/javascript">
//<![CDATA[
  ... unescaped script content ...
//]]>
</script>



It would be very nice for htmlcompressor to adhere script put into cdata.

Fixed in 0.9.1, but partially.

What's fixed is if JS block is wrapped with CDATA then it will be compressed 
correctly. But if CDATA is put inside comments (for older browsers) those 
comments 
will be treated as regular comments and removed by YUI. I can't solve this 
properly  
without writing JS parser, so if you want to keep browser compatibility and 
CDATA, 
then a workaround would be either disabling inline JS compression all together 
or 
putting inline JS into external files.

Style tags wrapped in CDATA blocks were handled by YUI correctly already, but 
again 
if you put CDATA inside comment they will be removed. Maybe this feature should 
be 
handled on YUI compressor side better.

Thanks.
