Hi, I am trying to create a new message using Java Node.

Code doesn't seem to set Attributes - just creates it as new tag.

Code snippet:

MbElement root = outMessage.getRootElement();

MbElement outBody = root.createElementAsLastChild(MbXMLNSC.PARSER_NAME);

MbElement document = outBody.createElementAsLastChild(MbElement.TYPE_NAME,"document",null);

MbElement chapter = document.createElementAsFirstChild(MbElement.TYPE_NAME,"Chapter",null);

MbElement title = chapter.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,"Title","new chapter");

XML Created is:-
<document><Chapter/><Title>new chapter</Title></document>

XML wanted:-

<document><Chapter title="new chapter"></Chapter></document>

Any help appreciated

Thanks

Jim

Hi, this is not an MQ Workflow question, apparently.

It seems it's a Message Broker Question.

Mods - please move.

You need to do the Java equivalent of

Code:

set OutputRoot.XMLNSC.document.chapter.(XMLNSC.Attribute)title = ;new chapter';

This is done by setting the parser specific type on your MbElement.

IBM sites imply doing the following piece of code below - but this just creates a new tag for me rather than attribute.

Most examples seem to transform the input message rather than create message from scratch.

MbElement title = chapter.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,"Title","new chapter");

That is necessary, but not sufficient. As you say, it creates the MbElement, but as an XMLNSC.Element rather than an XMLNSC.Attribute.

You need to also set the parser specific type. I'd recommend a review of the MbElement class definition to further understand what I'm telling.

XMLNS and XMLNSC are different parsers, and they use different field type constants to indicate attributes, comments, processing instructions etc.
For XMLNS, MbElement.TYPE_NAME_VALUE is indeed equivalent to XML.Attribute. The docs which suggest using this technique were probably written pre-v6.0, when XML and XMLNS were the only XML domains available.

Anyway, the answers you need are here: http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r1m0/topic/com.ibm.etools.mft.doc/ad21074_.htm
and here: http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r1m0/topic/com.ibm.etools.mft.doc/ac76040_.htm
along with quite a lot of other useful info.
