XML help.

[Alain-Serge]

Hello,
I'm trying to create a XML document from a string comming from a C++
program but I got an exception saying:

org.xml.sax.SAXParseException: Element type "DataFromWebServer" is not
declared
Here "DataFromWebServer" is the name of document root node. Here is
the code:

char cbuf[] = new char[2000];

//Get the data from the socket.
m_inputStream.read(cbuf);
String strdata = new String(cbuf);

//Qt Bug fix: Clean up the strdata.
String strFinalData = strdata.trim();
System.out.println(strFinalData);//For debug

InputSource in = new InputSource ((InputStream) new
ByteArrayInputStream (strFinalData.getBytes()));
XmlDocument xmlDocument =
XmlDocument.createXmlDocument(in, true);
///////////Here is what I got from
System.out.println(strFinalData)///////////

<?xml version = '1.0' encoding = 'UTF-8'?>
<DataFromWebServer>
<AddresseNode>
<Addresse>6</Addresse>
</AddresseNode>
<DatatypeNode>
<Datatype>25</Datatype>
</DatatypeNode>
<DataNode>
<data>6</data>
</DataNode>
</DataFromWebServer>
///////////Here is complete error message////////////////////////////

XmlDocument xmlDocument =
XmlDocument.createXmlDocument(in, true);
The second argument to createXmlDocument specifies whether to validate the
input stream XML.
org.xml.sax.SAXParseException: Element type "DataFromWebServer" is not declared.

This message means the DataFromWebServer element is not declared in the DTD.
<?xml version = '1.0' encoding = 'UTF-8'?>
<DataFromWebServer>
<AddresseNode>
<Addresse>6</Addresse>
</AddresseNode>
<DatatypeNode>
<Datatype>25</Datatype>
</DatatypeNode>
<DataNode>
<data>6</data>
</DataNode>
</DataFromWebServer>

This XML appears to be well-formed, but not valid. In particular, it does
not contain a !DOCTYPE declaration and DTD which is required for validation.

(In theory, this single entity could be validated, given some
system-dependent means (such as a catalog) for mapping a document type to
DTD. But this is probably not relevant to your situation.)

You can either turn off validation (easy) or add a !DOCTYPE declaration with
a DTD (not hard).
