Changing element names and (with care) attribute names or values, can be done with non-XML tools in the absence of XML namespaces. But if you had the expertise to do that (e.g. with Unix/Linux command-line tools) you probably wouldn't be asking here :-)

Changes to the tree structure - depends on the nature of the changes, but almost certainly best to use XML-aware tools.

One way - put the data into an XML database and use XQuery update. Or maybe it's already in a database - you didn't say.

Databases with XQuery update support include (as i understand it) IBM DB2, Oracle, Virtuoso, as well as XML-native systems such as BaseX, eXist, EMC, MarkLogic, Sedna, and, if they're still around, DataDirect (I get a security warning from the DataDirect site).

For sure there are more options.
