| I don't see why that matters...but.....i have been asked to find out what xml parser the broker is using by the aplication development team, they have their own xml parser and want to compare the two to see if the functionality is the same. |

Ask them if it's easier to use the supplied XML parser, or write and maintain a custom parser for WBIMB.
And then remind them that custom parsers for WBIMB can only be written in C.

On second thought, scratch that. 
They're probably looking to find out if there are unsupported features in the WBIMB parser compared to the XML standard.
The limitations of the XML parser are described in the documentation... somewhere...
It should be fully compliant with the W3C standard, so as long as they don't breach that, they should be okay. The Broker developers might need to use the XMLNS domain instead of the XML domain.

yeah, i think thats what they are after.
Ok, I'll have a dig round in the docs for the limitations.
Thanks for your input. |

You can use use the xml parser in the xml domain or MRM domain to parse your messages. IBM documentation says that the xml parser in the xml domain is faster than the one in MRM domain. Advantage of using xml parser in MRM domaini is to validate your messages.

I will be using the MRM parser as we have a need to validate the message.
Thanks |

The MRM domain XML parsing is slightly more limited than the unmodelled XML/XMLNS domain - I think.
But it's also much better documented!

| If I use the MRM and check the use namespace option, will this give the same functionality as the XMLNS parser? |

Hi,
WBI-MB V5 uses the IBM Xerces V2.2 C++ parser which is also equivalent to the xml4c 5.2 parser. The WMQI V2.1 product uses the IBM Xerces V1.3.1 C++ parser.
This is the same for both the XML, XMLNS and MRM-XML domains. However, the MRM-XML parser parses against a message model giving a slight overhead, but does allow for message validation and simpler transformations to other physical formats.

| If you are importing XML schema's, beware of limitations in MRM. |
