Hello!
I have another question:
I need to parse bitstream, which contains well-formatted xml structure with CDATA section. For example:

Code:
<root>
    <a>
        <![CDATA[<b><c><d>]]>
    </a>
</root>


It is to parse bit stream:

Code:
CREATE LASTCHILD OF element.DocBody DOMAIN 'XMLNSC' PARSE(source.File.FileBody OPTIONS FolderBitStream);


Then, I need to convert it back to bitstream:

Code:
CAST(ASBITSTREAM(element.DocBody CCSID 1208) AS CHARACTER CCSID 1208);


This is all work good. But have one problem - it resulting in such string:

Code:
<root>
    <a>
        &lt;b&gt;&lt;c&gt;&lt;d&gt;
    </a>
</root>


It is meaning, that broker lose information about CDATA in tag and convert special symbols (such as < > & ...) in it image.
How i can avoid this?..

P.S. Sorry for my English I would be thanks, if you specify on my mistakes

XMLNSC remembers that the data came from a CData section, and it will generate a CData section in the output. So you must have done something to the message tree after parsing. Did you copy it to the Environment or LocalEnvironment, perhaps?

I suggest that you put in at least two Trace nodes : the first one should go immediately after the CREATE...PARSE statement. You should see that the parser-specific field type is set to 'XMLNSC.CDataField' on element 'a'. Then put another Trace node just before the ASBITSTREAM. You will probably find that the XMLNSC.CDataField on element 'a' has disappeared because your flow has copied the tree incorrectly.
