vmclone.pl how to customize IP address for Guest OS?

I need to give a static IP to the guest OS after the clone by vmclone.pl. However, in the sample file, I only see a few items which can be customized:

<Specification>
   <Customization-Spec>
          <Auto-Logon>1</Auto-Logon>
          <Virtual-Machine-Name>TestVM</Virtual-Machine-Name>
      <Timezone>140</Timezone>
          <Domain>domain.com</Domain>
          <Domain-User-Name>username</Domain-User-Name>
          <Domain-User-Password>password</Domain-User-Password>
          <Full-Name>admin</Full-Name>
          <Organization-Name>companyname</Organization-Name>
   </Customization-Spec>
<Virtual-Machine-Spec>
      <Guest-Id>winXPProGuest</Guest-Id>
      <Memory>256</Memory>
      <Disksize>4194304</Disksize>
      <Number-of-CPUS>1</Number-of-CPUS>
  </Virtual-Machine-Spec>
</Specification>

Can someone advice how to pass a IP address to the guest OS?
