How to scan an entire array all at once

["M Boyce" <plexjob@xxxxxxxxxxx>]

Hello, I have a task that involves scanning a character array (or data 
structure) that is
8192 long by 256  (basically 2MB of data).    This data will come from an MQ 
message and will consist of a series of separate XML messages - 256 of them 
potentially - all strung together in one MQ message.

I want to write a function that will retrieve a subset of the xml message 
namely, the first instance of any element of the xml:

i.e.

<StateGroup> .....
</StateGroup>

Then I want to be able to remove the extracted subset from the original data 
and return the rest as well as the extracted xml (in two separate parms).

The problem arises when the xml fragment I want to extract is spread between 
two array elements.

Any ideas on an approach?

We are using V5R1 and we are also using Advantage Plex to create the server 
code but for this program I am thinking it would be best to use ILE RPG and 
just create a wrapper function in Plex (the Plex version we are using does 
not support ILE generation).

Thanks for any and all help you can provide.
