+ implementation, so maintaining this hopefully shouldn't be much work.) As
+ proof-of-concept, there are got Perl, PHP, Python and Ruby implementations
+ that work and feel largely the same (and even a SAX-based Perl
+ implementation, for larger trees that won't fit into memory) -- other
+ implementations are welcome. This is backed up by a test suite, which
+ ensures that all the different implementations return structurally
+ equivalent XML for a certain set of test cases. Porting to a new language
+ is not difficult, and once you've got all the test cases to pass, your
+ work is most likely done.
