[xmlc] Javascript output into XHTML: msg#00041

Subject: [xmlc] Javascript output into XHTML

This is very frustrating. I want to output some javascript into my document
via XMLC. The problem comes with < and > symbols. They get escaped into, for
example:
---
<script type="text/javascript">
for(var i=0;i &lt; someArray.length; i++)
{
// do stuff
}
</script>
---
This is invalid javascript, and generates an error in all the browsers I've
tried.

Personally, I find section 4.8 of the XHTML Specification
(http://www.w3.org/TR/xhtml1/#h-4.8) to be rather ridiculous. Why would the
contents of the <script> tag be PCDATA?!? Why would they force you to make
your javascript into CDATA just to do some comparisons or loops? I'd love to
hear any explanations other than "backwards compatibility" for this.

Note that this is not a problem at all if I make my mime type
"application/xhtml+xml", but then my page only works in Firefox, and I can't
use any innerHTML javascript. The latter, I could eschew, but the former is a
show stopper.

I can't use the org.w3c.dom.Document.createCDATASection() method, because that
results in something like:
---
<script type="text/javascript"><![CDATA[
for(var i=0;i < someArray.length; i++)
{
// do stuff
}
]]></script>
---
And that's not valid javascript either!

>From what I can tell from searching internet forums, you have to do something
>like:
---
<script>
<!-- // <![CDATA[ -->
for(var i=0;i < someArray.length; i++)
{
// do stuff
}
<!-- ]]> -->
</script>
---
Unfortunately, with the DOM methods available to me with XMLC, that's simply
impossible to output.

As far as I can see, the only solution to this is to put some lessThan(a, b)
and greaterThan(a, b) methods into an included js file. Obviously, this
solution is revolting, and I would love to hear any other suggestions you might
have.

Cheers,
Erik
