If the data is in XML Format, then there won't be a BLOB parser tree, nor a BLOB child node under that parser tree.
Unless you have coded specific things to make that happen. This is usually done with ASBITSTREAM.
You can not inquire of a message tree how long it is, in general.
Several other people have asked "How do I find out how long an XML document is, including the tags". I can't recommend a good search to find them, as there probably isn't one. Most of those original posters were not very clear on their questions.

Jeff,
Thank you very much for your clear and explanatory answer. I would appreciate it.
That means, we have to rely on validation ( though not the same - by creating a predefined Message Format ) for the auditing of the xml message. Or is there any better method?
Thanks |

I do not understand what you're asking.
If you wish to validate that a message against some arbitrary set of constraints in WMB, then yes you need to model the data and include those constraints.
This appears to have nothing to do with getting the length of the bitstream that represents an XML document.
