  1. POJava - SAX parser on a XHTML document
    text
    copied!<p>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 <a href="https://stackoverflow.com/questions/998280/dtd-download-error-while-parsing-xhtml-document-in-xom">here</a> that it was because W3C have intentionally blocked access to the DTD), but I fixed that with:</p> <pre><code>XMLReader reader = parser.getXMLReader(); reader.setFeature("http://apache.org/xml/features/disallow-doctype-decl",true); </code></pre> <p>However, now I'm experiencing a second problem. The SAX parser throws an exception when it reaches some Javascript embedded in the XHTML document:</p> <pre><code> &lt;script type="text/javascript" language="JavaScript"&gt; function checkForm() { answer = true; if (siw &amp;&amp; siw.selectingSomething) answer = false; return answer; }// &lt;/script&gt; </code></pre> <p>Specifically the parser throws an error once it reaches the &amp;&amp;'s, as it's expecting an entity reference. The exact exception is:</p> <pre><code>`org.xml.sax.SAXParseException: The entity name must immediately follow the '&amp;' in the entity reference. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:198) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:177) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:391) at com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1390) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEntityReference(XMLDocumentFragmentScannerImpl.java:1814) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:3000) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:624) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:486) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:810) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:740) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:110) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1208) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:525) at MLIAParser.readPage(MLIAParser.java:55) at MLIAParser.main(MLIAParser.java:75)` </code></pre> <p>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?</p> <p>Cheers,</p> <p>Pete</p>
