What method would you preffer? This is my problem: For some automatic reading procedure I need well defined tree-names (eg, data tree: Data, corresponding Header-tree: DataHeaders) But we have old files which don't follow this convention. Now I want to write a small tool which 'converts' the old files such that they fit the new scheme... Thomas.
