  Yes, thats the plan

  The QDomDocument can be reused, so parsing is only done once. Iteration needs to be done twice, but this is only a minor issue as the metadata documents are **really** small (~10 nodes, 1kByte). For the office2007extractor it actually is a win, as it currently iterates the tree once per property.
