I need to display some data from an XML file in a list, but unsure how to exactly handle it.

The data looks like this:

<Parents>
   <Parent Name="Parent1">
      <Child Title="Child1" Print="Y" Active="Y" PrintPath="C:\Print" LogPath="C:\Log" />
      <Child Title="Child2" Print="Y" Active="Y" PrintPath="C:\Print" LogPath="C:\Log" />
   </Parent>
   <Parent Name="Parent2">
      <Child Title="Child1" Print="Y" Active="Y" PrintPath="C:\Print" LogPath="C:\Log" />
   </Parent>
   <Parent Name="Parent3">
      <Child Title="Child3" Print="Y" Active="Y" PrintPath="C:\Print" LogPath="C:\Log" />
   </Parent>
</Parents>

Here's how the user wants things displayed. (The ^ indicates an Expander):

^ Parent: Parent1
    ^ Child: Child1
        Print: Y   Active: Y           
        Print Path: C:\Print
        Log Path: C:\LogPath
    ^ Child: Child2
        Print: Y   Active: Y           
        Print Path: C:\Print
        Log Path: C:\LogPath
^ Parent:  Parent2

Here are the issues:
- There can be multiple Parent elements
- There can be multiple child elements per parent
- Any parent or child can be deleted
- Any parent or child can be copied and pasted
- A new parent or child can be added

I'm thinking of solving it this way:
- Place everthing in a list box
- Put parent records in an expander
- Put a stack panel in the Parent expander
- Put child records in an expander in the stack panel and use a group box to hold the attributes

Here's what I'm not sure about:
How do I handle an unknown number of child records per parent?
How do I deal with insert/delete of child records?

I'll take any suggestions for solving this.
