Child nodes ordering sequence

[knp]

I have the following xml piece:

https://gist.github.com/anonymous/7934085

<list>
  <compressor tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[2]">
    <status tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[2].status">0</status>
    <status_display tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[2].s_d">On-No Response</status_display>
    <size tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[2].SZ">
      <setpoint tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[2].SZ.set">20.00</setpoint>
    </size>
  </compressor>                       
  <compressor tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[1]">
    <status tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[1].status">0</status>
    <status_display tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[1].s_d">On-No Response</status_display>
    <size tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[1].SZ">
      <setpoint tag_id="SYS.RKS.RK[1].SGS.SG[1].CPS.CP[1].SZ.set">20.00</setpoint>
    </size>
  </compressor>
</list>

The above is just a piece of the whole xml and it could be nested at any level.
The original xml had them in the reverse sequence.

I get a lot of not tag_id not matching because their sequence is different though values are same.
How do I ignore the sequence errors on this? Or how do I make sure I am comparing them properly even if their sequence is different?

This kind of a piece of xml can occur in several places in the whole xml file so there is no particular case of element name i can separate and do a different kind of processing.

Please advise.

At first glance it looks as if using an ElementNameAndAttributeQualifier (see http://xmlunit.sourceforge.net/userguide/html/ar01s03.html#ElementQualifier ) should do the trick.
