XPath Drill Down
The underlying data displayed here is the same as used in the XPath Graph
The view shows the drill down to the elements under the document/body/text.
The table is just a javascript thing and should be available to all users. The graph view however is dependent upon having GraphViz installed. The ODF Explorer should run just the same but the resulting dot files will not be processed to produce graphs.
See the discussion in the graph for more information.
