Hey Monks, it's me again. I have an inputfile. It Looks like this: 
<class="abc">
  <polygon>
  <polygon>
  <rectangle>
</class>

<class="def">
  <polygon>
  <rectangle>
  <rectangle>
</class>

And my question is, how to save which polygon and rectangle belongs to which class. Because I want to create an Outputfile, where i have to list all Polygons and rectangle. The Polygons and rectangles differs because of coordinates, they also contain. The Output should be like this: 

<polygon class ="abc" coordinates="..">
<polygon class="abc" coordinates="--">
#and so on

Could someone explain me, how I should solve this Problem, that every polygon and rectangle know to which class they belong? I thought some hashes could help, but do not know how to create them. Thanks Regards
