Can't parse XML data

Question

I'm receiving an XML document over a TCP socket, I then instantiate an instance of DOMParser and attempt to parse the data. Here's the exception:
org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x0) was found in markup after the end of the element content.
     at org.apache.xerces.framework.XMLParser.reportError(XMLParser.java:1213)
     at org.apache.xerces.framework.XMLDocumentScanner.reportFatalXMLError(XMLDocumentScanner.java:588)
     at org.apache.xerces.framework.XMLDocumentScanner$TrailingMiscDispatcher.dispatch(XMLDocumentScanner.java:1461)
     at org.apache.xerces.framework.XMLDocumentScanner.parseSome(XMLDocumentScanner.java:381)
     at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:1098)
Here's the relevant snippet(s) of source (there is code to write out the socket, but I didn't include that)
Socket socket = new Socket( hostIP, hostPort );
OutputStream outStream = socket.getOutputStream();
InputStream inStream = socket.getInputStream();
DataInputStream dataInStream = new DataInputStream( inStream );
byte[] inByteArray  = new byte[ 2048 ];
int length =  dataInStream.read( inByteArray );
InputStream byteData  =  new ByteArrayInputStream( inByteArray );
try
       DOMParser dp = new DOMParser();
       dp.parse( new InputSource( byteData ));
       Document doc = dp.getDocument();
catch ( Exception e )
        e.printStackTrace();
        System.exit( 1 );
}Is there a different way to do this? I even tried creating a new String based on the length read from the socket, minus one. The parser then saw that the final angle bracket of my root element was missing, so it doesn't seem to be an encoding issue.
Any help would be appreciated.

An invalid XML character (Unicode: 0x0)The XML is corrupt.
...saw that the final angle bracket of my rootelement was missing,
After you subtracted one from the length - that would
suggest that not subtracting one would be a good
idea.Yep. That was a test to verify that the data was in tact and not null terminated. To doubly check, I took an Ethereal trace of the wire, and there was no null. If I convert the byte[] to a String, everything is fine. Unfortunately,
there wasn't a parser method that took the XML document as a String.

I would suppose that the real problem here has
nothing to do with XML nor DOM but rather that you
are not correctly retreiving the data from the socket.Data is fine from the socket, I just had to implement my own getAttribute() and getElementContent, and use brute force. I just thought using an already written parser made more sense.
Thanks for the reply.
