Re: [dom4j-dev] DocumentHelper.parseText data corruption after <

[Filip Jirsák]

It seems it is SAX parser problem. I tested it with JDK 1.6 (
com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl) and it printed eights
in test7 attribute. But it gots this attribute value from SAX parser. You
can test this:

public class Test {
private static class Handler extends DefaultHandler {

@Override
public void startElement(String uri, String localName, String name,
Attributes attributes) throws SAXException {
super.startElement(uri, localName, name, attributes);
System.out.println(MessageFormat.format("element: ",localName));
for (int i = 0; i < attributes.getLength(); i++) {
System.out.println (MessageFormat.format("{0}={1}", attributes.getLocalName(i),
attributes.getValue(i)));
}
System.out.println("");
}
}

public static String xmlString = "<?xml version=\" 1.0\"
encoding=\"UTF-8\"?><Test test1=\"11111 &lt;\" test2=\"22222 &lt;\"
test3=\"33333 &lt;\" test4=\"44444 &lt;\" test5=\"55555 &lt;\" test6=\"66666
&lt;\" test7=\"77777 &lt;\" test8=\"88888 &lt;\" test9=\"99999 &lt;\"
test10=\"101010101010 &lt;\" />";

public static void main(String[] args) throws Exception {
SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
parser.parse(new InputSource(new StringReader(xmlString)),
new Handler());
}
}

Inspect your XML once more, if there is not problem with quotation or
something else – but I think document is OK. If it is correct, report this
bug to Sun – it seems it is bug of their platform's SAX parser.
