Yes, you can implement loop within a message flow. I can explain better if I know what exactly you want to do. Please explain your requirement.
This topic has been discussed in this forum before. Do a search on "loop" and you will be able to find the thread.

If you have input message containing repeating elements and you want to insert them into database in a loop, you can do it in a single compute or DB node. Here is the pseudo code,
| Code: |
i=1;
cnt = cardinality(inputmessage.repeatingelement[])
while ( i<=cnt)
insert into database.sometable(field1,field2,...) values (inputmessage.repeatingelement[i].value1, inputmessage.repeatingelement[i].value2, ...)
set i = i+1;
end while;
|
What document you are referring to?

I have several DataInsert Nodes to update multiple tables.
And i have a computational node before them to loop thru the data then propagate one by one to the 1st DataInsert Node,
is this a correct method to do it...?
Sidetrack abit 
I have a message set which defines : File->Line(s)->Elements
When i put a file containing one line into the queue, it parses it correctly but doesn't for multiple lines, what could be the reason...?
I've set the Group Terminator under the TDF to be <CR><LF> for each Line Type... |

This is how I would do it!

What is the exact BIP error you are getting? Can you post ExceptionList here?

There is no error when i send in a file with one line for parsing, however when i send in a text file with multiple lines into the queue, then the error below happens :
| Quote: |
"The TDF parser could not complete parsing because the bitstream contains more data than expected. This could be caused by either an incorrect message definition or by an incorrect message."
|
Lets say i want to define a message set with elements like this
<File>
<line>
<astring></astring>
<bstring></bstring>
<cstring></cstring>
</line>
</File>
How should i do it? Right now it only parses files with just one line element correctly.[/quote] |
