Faster than what? Going through the BLOB byte by byte in ESQL? Printing it out, going through it by hand & typing it back in?

Almost certainly!

Hi,

There is a way to do XML conversion at wire speed using IBM's datapower technology.

You can find more information here:

http://www.datapower.com/products/xa35.html

Cheers,

Mark

Yes , there almost certainly is. If you tell us
- what your 'BLOB data' is
- what you want to do with it
- which version of message broker you are using
- what you have tried so far
...then somebody might be able to help.

I think DataPower is an XML-only technology. I don't think it handles conversion of non-XML data to XML.

There are a few different models of the DataPower appliance.

The most advanced of them do any-to-any, and include MQ connectivity.

http://www.datapower.com/products/xi50.html

It's also priced about the same as Broker for one unit, I believe.
And I believe the development toolkit is not as nice as WMBT.

Thanks Jeff. Apologies to DataPower for the misrepresentation.
I did check the referenced page before I posted, but I didn't notice the page that Jeff posted.

You mean IBM?

IBM bought DataPower earlier this year.

Hi all,

Thanks for the reply. I need to change blob data to xml. the blob data is just some character. I am using Broker V6. Is there any idea other than buying? Tight budget. I read on the XML transformation node but I think it can only change XML to XML. Thanks for help

Broker is perfectly capable of transforming "blob" data to XML.

You asked a really bad question.

Nobody understood it. So we babbled about other things for a bit.

What, exactly are you trying to do?

What, exactly, have you already done?

Broker is not an easy product to learn on your own. If you don't, for example, know how to use it to tranform "blob" data to XML, then you barely understand the product at all and should get some training.

Please go back and read the Information Center introductory and "Developing Applications" sections again.

Here is a redbook that may help as well. http://www.redbooks.ibm.com/abstracts/sg247137.html

You need to read, think, and TRY things in order to learn.

We're not going to provide you free training.

Hi,

What I did is to go thru bytes by bytes of the data and then set it to the OutputRoot.XML.data etc. is there a easier way? cos the format of the data may varies. Thanks

Yes, there is an easier way.

You can create a MODEL of your BLOB data, and then use the Mapping node to move it to XML.

You need training on this product! Or you need to read what I suggested, and try things, and learn!

Aha! So you must know how to parse this 'BLOB' data. Please provide the following information:
- What does an example mesage look like ( give a real example if possible)
- What message tree would you like to construct ( you are already constructing one using ESQL, so tell us about that ).

Hi all,

Is there any documentation on how to create MODEL of BLOB data? I am using Mapping node. But the example and documentation which i found is from XML to XML.. my message is like "s48739284f d 12345 ffff" sth like this. Thanks
