Hi,
We have a requirement to split a XML(read from file) and propagate to target.
XML structure will look like
| Code: |
<a>
<b>
<c>d</c>
<c>e</c>
<c> f</c>
</b>
</a>
|
Target should receive 3 messages here from segment <c>.
My question is
| Quote: |
| Is there any inbuilt capability in IIB to perform it using FileRead node |
I can do the split using XSLT/ ESQl/JAVA. File size being big, wanted to confirm if it is a good idea to perform the split in IIB?
Does it provides any inbuilt feature? |

Formatted how?

Why a FileRead not a FileInput?

There's specific advice in the InfoCenter about handing large files.

You mean "does it have a 'split the file up how I want' button"?
No
It can't possibly know how you want the file parsed or the output formatted.
You can certain use the inbuilt faciltites it does have to achive this in a very few lines of ESQL or even (depending on output format) get the Mapping node to do the work for you. I'll leave others to speak on Java & XSLT.

Use a file read node if you like
I think IIB is a good idea for your task!
I would use ESQL and PROPAGATE (TO ...) "RETURN FALSE" to create the individual messages

Sometimes FileRead is the correct solution, but not in this case.
The only way I know to do this efficiently is to use the technique described here: http://www.ibm.com/developerworks/websphere/library/techarticles/0505_storey/0505_storey.html
However, please remember that this article was written many years ago. Do not use the MRM parser for processing the XML input - XMLNSC is the correct choice.
