Nested grouping using XSLT muenchian-grouping

I had to group a xml document in xslt 1.0 using Oracle Service Bus.

This is the sample input file(Simplified):

    <?xml version="1.0" encoding="UTF-8"?>
    <EMailData>
       <property name="A">
          <property name="B">
               <property name="C">
                <row>
                   <property name="C1">
                      <value>ValC1</value>
                   </property>
                   <property name="C2">
                      <value>ValC2</value>
                   </property>
                   <property name="C3">
                      <value>Valc3</value>
