I am trying to use the delete function to remove a part of the input message tree and i am getting the following error...
| Quote: |
2004-02-16 15:01:56.659000 385 RecoverableException BIP2230E: Error detected whilst processing a message in node 'Check_XMLAttr.Compute1'.
The message broker detected an error whilst processing a message in node 'Check_XMLAttr.Compute1'. An exception has been thrown to cut short the processing of the message.
See the following messages for details of the error.
2004-02-16 15:01:56.659000 385 RecoverableException BIP2536E: (19, 1) : The dynamic field reference supplied to the DELETE statement does not resolve to a non-list field in a modifiable message tree.
The dynamic field reference supplied to the DELETE statement must resolve to a non-list field in a modifiable message tree.
Ensure that only non-list references to modifiable trees are passed to the DELETE statement. |
here is my ESQL
| Quote: |
DELETE FIELD InputRoot.XML.parent.chid2.subchild1;
DELETE FIELD InputRoot.XML.parent.child2 |
here is my input message
| Quote: |
<parent>
<child1>abc</child1>
<child2>
<subchild1>hello</subchild1>
</child2>
</parent> |
Please let me know.
Thanks,
 |

| The Error states that you doesn't have the field to delete.are you sure you are deleting the field which exists. |

This error message is actually telling you that you cannot delete part of a message tree that is not modifiable. In your case you CANNOT change or DELETE InputRoot (or any sub-tree of it) in anyway. Therefore, you have to use DELETE on a copy of the input message in OutputRoot or the Environment etc. Or you could simply copy only the bits you want from InputRoot to OutputRoot and avoid having to do a DELETE altogether.
You should also make sure that any reference passed to DELETE is correct, as you seem to have mis-spelt "chid2" below (I assume you ment child2)?
Cheers,
