Hey,
I'm trying to write a SAX parser for an XHTML document that I download from the web. At first I was having a problem with the doctype declaration (I found out from here that it was because W3C have intentionally blocked access to the DTD), but I fixed that with:
XMLReader reader = parser.getXMLReader();
reader.setFeature("http://apache.org/xml/features/disallow-doctype-decl",true);
However, now I'm experiencing a second problem. The SAX parser throws an exception when it reaches some Javascript embedded in the XHTML document:
<script type="text/javascript" language="JavaScript">
function checkForm() {
answer = true;
if (siw && siw.selectingSomething)
answer = false;
return answer;
}//
</script>
Specifically the parser throws an error once it reaches the &&'s, as it's expecting an entity reference. The exact exception is:
`org.xml.sax.SAXParseException: The entity name must immediately follow the '&' in the entity reference.

I suspect (but I don't know) that if I hadn't disabled the DTD then I wouldn't get this error. So, how can I avoid the DTD error and avoid the entity reference error?
Cheers,
Pete
