hi ..
I was trying to set the xml element value as NULL
If I say OutputRoot.XML.ABC.element = null - then element itself is becoming null ... not the value ...
In some pdf .. I had read usage of verb value ..but not able to recollect the exact syntax ...
hope to get a quick answer ..
thanks

This is in the ESQL reference.
| Code: |
| Set OutputRoot.XML.ABC.element VALUE = null; |
will create
| Code: |
| <ABC><element>NULL</element></ABC> |
This only works in 2.1, as far as I know, and only in some of the newer CSDs. |

thanks for the quick turn around...
but, have a following question ... 
How can I check for InputRoot ?
if (InputRoot.XML.ABC."Element" value is null ) ....
is throwing syntax exception ...
Am I suppose to use InputRoot.XML.ABC."Element" = '' ?
Thanks again

The value qualifier only applies in set statements, and is only to indicate that you specifically want to only set the value, and not delete the tag in question.
| Code: |
| If (InputRoot.XML.ABC."Element" is null) |

Actually it depends on what your application expect. I mean if 'null' value for you is empty tag?
| Code: |
| OutputRoot.XML.ABC.element = '' |
will create message as <ABC><element></element></ABC>
