I need to extract XML element from an xml message as a string. I'm totally new to WBI and struggling to figure this out. I have an XML message like
<Root>
<Group>
<Element1>
<Ele1-Child1>name1</Ele1-Child1>
<Ele1-Child2>name2</Ele1-Child2>
</Element1>
<Element2> .... </Element2>
</Group>
<Group>
<Element1> ..... </Element1>
<Element2> ..... </Element2>
</Group>
</Root>
I need to extract <Element1> and its content as a string.
I have a Java Compute node where I need to create a string
String s = "<Element1><Ele1-Child1>name1</Ele1-Child1><Ele1-Child2>name2</Ele1-Child2></Element1>";
Any help is really appreciated. Thanks in advance. |

You need 'ASBITSTREAM'.

May I suggest a different approach?
Just move the tags as reference and the children will move with them...
Think about it

How will that turn a message tree into a string?

Well from what I can see he is moving a 'node' from place a to place b.
Now if he wants to coat this as a CDATA he will need to use ASBITSTREAM but this may still allow him to take advantage of the reference.
Sorry I did not take into consideration that the target of his java method might not be some node. My mistake.

Thanks for the reply.
Is there a way to do this in Java without having to use ESQL? |

You can use MBSQLStatement to call ASBITSTREAM from Java.
Or you can experiment with the toBitstream method on MBElement. It might not work on anything other than the root element, though.

When i try
MbElement.toBitstream(null,null,null,0,0,0) it fails. Not sure what am I doing wrong here.
The MbElement that I am trying to convert to the bitstream has a structure like this
<Name>
<first Name/>
<last name/>
<personal>
<subele1/>
<subele2/>
</personal>
</Name> |

You probably need to pass valid parameters to toBitstream. The Info Center describes the parameters to this call in the reference section on writing Java plug-in nodes. It's the same API in Java Compute Nodes.
Also, it might not work on anything other than the root element.
