How to split a node value which has xml as string in xslt - xslt

Question

We have a requirement where we are getting an XML payload in form of String for one node and we need to expand this XML and pass the XML node values to destination XSD columns.
For example Input XSD :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Transaction xmlns="http://xmlns.oracle.com/2012/SCEM">
<TRXKEY>0x0000013</TRXKEY>
<EVENTNAME>SalesOrder</EVENTNAME>
<ACCEPTEDQUANTITY>0</ACCEPTEDQUANTITY>
<ORDEREDQUANTITY>0</ORDEREDQUANTITY>
<SOLORGID>0</SOLORGID>
<LHORDERHOLDIDRELEASED>0</LHORDERHOLDIDRELEASED>
<ORDEREDQUANTITYUOM>0</ORDEREDQUANTITYUOM>
<UNITSELLINGPRICE>0</UNITSELLINGPRICE>
<ORDERTYPE><Val lang='AR'>OrderTypeARARARAR</Val>
<Val lang='KO'>OrderTypeKOKOKOKO</Val>
<Val lang='US'>OrderTypeUSUSUUS</Val>
</ORDERTYPE>
</Transaction>
Output XML
<Transaction1 xmlns="http://xmlns.oracle.com/2012/SCEM">
<TRXKEY>0x0000013</TRXKEY>
<EVENTNAME>SalesOrder</EVENTNAME>
<ACCEPTEDQUANTITY>0</ACCEPTEDQUANTITY>
<ORDEREDQUANTITY>0</ORDEREDQUANTITY>
<SOLORGID>0</SOLORGID>
<LHORDERHOLDIDRELEASED>0</LHORDERHOLDIDRELEASED>
<ORDEREDQUANTITYUOM>0</ORDEREDQUANTITYUOM>
<UNITSELLINGPRICE>0</UNITSELLINGPRICE>
<ORDERTYPE_AR>OrderTypeARARARAR</ORDERTYPE_AR>
<ORDERTYPE_US>OrderTypeUSUSUUS</ORDERTYPE_US>
<ORDERTYPE_KO>OrderTypeKOKOKOKO</ORDERTYPE_KO>
</Transaction>
We need to loop through the ORDERTYPE node XML string. Depending on the 'Val lang=' value we need to pass this node value to output XSD ORDERTYPE_$lang value column.
How can I loop through this XML string for these 2 different values and pass it to the corresponding output XML column?
I was thinking of using split but it is not helping much.

Thanks Martin,
I have come up with below code which resolved my issue.
