CMakeLists parse file

I would like to parse a file (XML, JSON or similar) in my CMakeLists and set some variables accordingly.

For example, say I have the following file:

<root>
 <Object>
  <name = "my_name"/>
  <url = "my_url"/>
 </Object> 
 <Object>
  <name = "another_name"/>
  <url = "another_url"/>
 </Object> 
</root>

and then in my CMakeLists I would like to set a variable with all the names and another variable with all the urls.

Is that possible? I haven't found much on this topic.

Thank You

Carl.
