Challange with message split

Question

Hi All.
I have to create a several files from one file according to the  customer number
and I have to attach the right reference to the right customer positon number
let say I have the follwong file
<libarary>
<customer>
<pos>1</pos>
<nr>1</nr>
</customer>
<customer>
<pos>2</pos>
<nr>1</nr>
</customer>
<customer>
<pos>3</pos>
<nr>2</nr>
</customer>
<customer>
<pos>4</pos>
<nr>2</nr>
</customer>
<references>
<ref>1</ref>
<ref>2</ref>
<ref>3</ref>
<ref>4</ref>
</references>
</libarary>
according to the requirement I  have to create 2 files , one for customer 1 and one for customer 2.
this is can be achieved by using split by value function to create 2 or more  files , but my the challenge is  how can I attache the ref field to the right pos field.
which means ref 1 and ref 2 should go to the file with pos 1 and pos 2 and  ref 3 and ref 4 should go to the file with pos 3 and pos 4
the finale result should be like this
File 1
<File>
<customer>
<pos>1</pos>
<nr>1</nr>
</customer>
<customer>
<pos>2</pos>
<nr>1</nr>
</customer>
<references>
<ref>1</ref>
<ref>2</ref>
</references>
</File>
File 2
<File>
<customer>
<pos>3</pos>
<nr>2</nr>
</customer>
<customer>
<pos>4</pos>
<nr>2</nr>
</customer>
<references>
<ref>3</ref>
<ref>4</ref>
</references>
</File>
Any help will be higly apreciated
Thank you.

You have make sure all the levels properly mapped:
libarary/customer/nr -> removeConext() ->splitByvalue[ValueChange] -> CollapsContext() -> File
libarary/customer/nr -> removeConext() ->splitByvalue[ValueChange] -> customer
libarary/customer/nr -> removeConext() ->splitByvalue[ValueChange] -> CollapsContext() -> SplitByvalue[each value] -> File/customer/references
reference/ref----

                                                                    FormatByExample() -> ref
libarary/customer/nr -> removeConext ->splitByvalue[ValueChange]-->
libarary/customer/nr -> File/customer/nr
