Hello monks,
I have the following XML file structure: 
  <attr-name>model_name</attr-name>
    <alternate>
      <mtype>0x234567</mtype>          
      <attr-id>0x654321</attr-id>             
    </alternate>
    <default-id>0x654321</default-id>        
    
  <attr-name>security_string</attr-name>
    <alternate>
      <mtype></mtype>          
      <attr-id></attr-id>           
    </alternate>
    <default-id>0x123456</default-id>

What I need to do is have the default-id point to the attr-name for a mtype I pass in unless a mtype is specified, and in that case I need to have that mtype point to the attr-id specified. (i.e)

for security_string I pass in mtype 0x23456 so it uses the default-id of 0x10009 but in the case of model name it should use the attr-id of 0x654321.

Any suggestions for a data structure or alogorithm to use?
