[basex-talk] Transform table to tree

I have a table that is to be transformed to a tree: <entry id="entry1" parentId="parentOfThisEntry" /> <entry id="entry2" parentId="parentOfThisEntry" /> <entry id="entry3" parentId="parentOfThisEntry" /> <entry id="entry4" parentId="parentOfThisEntry" /> The tree structure can be constructed by the id/parentId relation. I failed to achieve this... :-( I am using basex 6.5.
