editing xmldiff format

I’m using XMLdiffpatch tool to detect changes between two xml files , the output xml file of the tool looks like this :

<?xml version="1.0" encoding="utf-16"?>
<xd:xmldiff version="1.0" srcDocHash="5708212576896487287" options="None" fragments="no" xmlns:xd="http://www.microsoft.com/xmldiff">
    <xd:node match="2">
        <xd:node match="3"/>
        <xd:add>
            <e>Some text 4</e>
            <f>Some text 5</f>
        </xd:add>
        <xd:node match="4">
            <xd:change match="1">Changed text</xd:change>
            <xd:remove match="2"/>
        </xd:node>
        <xd:node match="5">
            <xd:remove match="@secondAttr"/>
            <xd:add type="2" name="newAttr">new value</xd:add>
            <xd:change match="@firstAttr">changed attribute value</xd:change>
        </xd:node>
        <xd:remove match="6" opid="1"/>
        <xd:add type="1" name="p">
            <xd:add type="1" name="q">
                <xd:add match="/2/6" opid="1"/>
            </xd:add>
        </xd:add>
    </xd:node>
    <xd:descriptor opid="1" type="move"/>
</xd:xmldiff>
First File :

<?xml version="1.0"?>
<b>
  <a>Some text 1</a>
  <b>Some text 2</b>
  <c>Some text 3</c>
  <d>
    Another text
    <foo/>
  </d>
  <x firstAttr="value1" secondAttr="value2"/>
  <y>
    <!--Any comments?-->
    <z id="10">Just another text</z>
  </y>
</b>
Second file :

<?xml version="1.0"?>
<b>
  <a>Some text 1</a>
  <b>Some text 2</b>
  <c>Some text 3</c>
  <e>Some text 4</e>
  <f>Some text 5</f>
  <d>Changed text</d>
  <x firstAttr="changed attribute value" newAttr="new value"/>
  <p>
    <q>
      <y>
        <!--Any comments?-->
        <z id="10">Just another text</z>
      </y>
    </q>
  </p>
</b>
as you see , the xml displays the detected node changes upon their index corresponding to their parent nodes .
The problem I’m facing now is how to parse these indexes , in order to replace them with their actual node names in the original xml file .
