Splitting a xmt into multile xmls based on a criteria using xsl

Hi,, I am new to xml. I would like to split an incoming xml based on a 
certain criteria. For example In comming XML:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="C:\projects\xml\dat\TEST2.xsl"?>
<TRANS>
        <ID>009</ID>
        <DESC>New Product</DESC>
        <VENDOR>
                <NAME>ACME</NAME>
                <ADDRESS>45 Cross Street</ADDRESS>
        </VENDOR>
        <BRANCH>4007</BRANCH>
        <BRANCH>5007</BRANCH>
        <BRANCH>6007</BRANCH>
</TRANS>

My output should be as follows:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="C:\projects\xml\dat\TEST2.xsl"?>
<TRANS>
        <ID>009</ID>
        <DESC>New Product</DESC>
        <VENDOR>
                <NAME>ACME</NAME>
                <ADDRESS>45 Cross Street</ADDRESS>
        </VENDOR>
        <BRANCH>4007</BRANCH>
</TRANS>
========================================================================

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="C:\projects\xml\dat\TEST2.xsl"?>
<TRANS>
        <ID>009</ID>
        <DESC>New Product</DESC>
        <VENDOR>
                <NAME>ACME</NAME>
                <ADDRESS>45 Cross Street</ADDRESS>
        </VENDOR>
        <BRANCH>5007</BRANCH>
        </TRANS>
========================================================================

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="C:\projects\xml\dat\TEST2.xsl"?>
<TRANS>
        <ID>009</ID>
        <DESC>New Product</DESC>
        <VENDOR>
                <NAME>ACME</NAME>
                <ADDRESS>45 Cross Street</ADDRESS>
        </VENDOR>
       <BRANCH>6007</BRANCH>
</TRANS>
