org.xml.sax.SAXParseException：文件过早结束

Question

I'm using Java 6, trying to parse this namespace-less XML ...

<gen type='section' name='Gen Info'>     
     <pmult type='input' name='Price Multiplier' nwidth='200' vlength='10'>
        1000.0 
     </pmult>
     <tunit type='input' name='Trading Unit' nwidth='200' vlength='10'>
        BBL
     </tunit>
     <tmsure type='input' name='Trading Measure' nwidth='200' vlength='10'>
        1000.0
     </tmsure>
</gen>

and getting this error ...

Below is the Java code I'm using to parse it ...

public static com.cme.clearing.commons.xml.Node parse(String xml) throws 
        ParserConfigurationException, SAXException, IOException {
    xml = xml.trim();
    return parse(new ByteArrayInputStream(xml.getBytes()));
}

public static com.cme.clearing.commons.xml.Node parse(final InputStream xmlInputStream)
        throws ParserConfigurationException,
        SAXException, IOException {

    final DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    final DocumentBuilder db = dbf.newDocumentBuilder();
    final Document doc = db.parse(xmlInputStream);

Any ideas what's malformed about the XML or what's wrong with the parsing logic? - Dave

I think it is possibly a bug in the SAXParser in that version. This is the same problem I ran into with IBM's JDK. I ended up using the -Xbootclasspath option to drop in a different version of the SAXParser (download xerces.jar and xml-api.jar) in order to solve the problem. Huge pain, but it works.
