David,
Thanks for these. To do any useful R work we'll still need to import the
records into R objects, but it might be possible to use this to limit the number of records that are read in from the XML file, e.g. selecting the first n records, records that match a pattern or perhaps a random sample of records.
Glad they might be of some use.
Even if it only restricts the number of records imported, that would seem to be really useful when dealing with very large data sets.
