How to create tXMLMap nested loops

[Anonymous]

I have the below flow, and I would like the userGroup to be a loop as well according to data that's coming from another database lookup, Can you point me to the best way to approach this, I'm not able to do it right now.

Your help is appreciated.

I followed the example in here: https://community.talend.com/t5/How-Tos-and-Best-Practices/prepare-XML-with-multiple-loop-in-same-le...

But the problem is when it gets to the lookup part it won't bring all the user groups, it will bring only one row. 

here is the flow:

here is the tCMLMap_3:

Here is the tMap_1

Here is the expression to replace the string:

row10.userGroup==null?
row9.payload.replaceAll("<UserGroups>WIRECODE_PLACEHOLDER</UserGroups>", "")
:row9.payload.replaceAll("<UserGroups>WIRECODE_PLACEHOLDER</UserGroups>", row10.userGroup)

Here is tTeradataInput_2:

Here is the resulted user node in the XML:

Here is the expected user groups:

is there something wrong with the way I do the join?

Your help appreciated!
