Strange problem in converting between XML to string and vice versa

Question

i have an application that needs to send an XML document
over the wire. For this reason, I need to convert the
doc into a String at the sending side and back to Doc
at the receiving side. This document is stored in a "CLOB"
column in a table in the database. I use XDK to retrieve
this entire row (including the CLOB - hence this is an XML
document which has a column that itself is an xml document in
string format - this is just the clob read in by XDK).
Thus the row looks like
<ROWSET>
<ROW>
<col1> A <col1>
<CLOB_COL> ..clob value of an xml doc..</CLOB_COL>
</ROW>
</ROWSET>
When I convert this document into String and back, one of the "<"
tags in the clob column document gets changed to "&lt;" and hence
the parsing fails! I have used the latest label of the XDK build
to get the latest parser jar but still i have the same problem.
I am using the following routines for the conversion.
/* for converting document to string */
public static String convertToString(XMLDocument xml) throws
IOException
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
xml.print(pw);
String result = sw.toString();
return result;
/* for converting string to document */
public static XMLDocument convertToXml(String xmlStr)
throws
IOException,SAXException
ByteArrayInputStream inStream = new
ByteArrayInputStream(xmlStr.getBytes());
DOMParser parser = new DOMParser();
parser.setPreserveWhitespace(false);
parser.parse(inStream);
return parser.getDocument();

How do you get the XML document? Do you use XSU? You can use:
String str = qry.getXMLString();
to get the result XML document in String.
XSU will escape all of the < and >. Or the the XML document in
one of the column will make the result XML doc not well-formed.
Not quite understand your problem. You can send me your test
case.
