Test XML file and Message Mapping test tab not compatible

Hi all,

I need help in testing in message mapping test tab.

I have a xml data taken from SXMB_MONI which looks lik below

&?xml version='1.0' encoding='UTF-8'?>

-&ns0:MT_Order xmlns:ns0="http://test.com/xi/test">

-<Header>

      <fld1>

      <fld2>      

    -<Line>

        <line1>

and in message mapping multimapping is used,so it looks like

ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">

   <ns0:Message1>

      <ns1:KVNR_Senden_MT xmlns:ns1="urn:lsv.de/SENDER">

         <Inhalt>

            <KE/>

            <VF/>

            <BBNRAB/>

            <BBNREP/>

how can test this xml in message mapping test tab?please don't consider the structure .I don't have them.So,i have pasted some dummy structure
