Jack,
It seems to be only the Ant build for Tagsoup that requires Saxon 6.5.
You can run the binary distribution (tagsoup-1.2.jar) without Saxon and, as
Michael has pointed out, the code you posted has no dependency on Saxon.
You may have an environment or classpath issue given that the following
class (which is your code with typo 'saxbuilder' changed to 'saxBuilder'),
outputs what you are expecting:

OUTPUT:
===================
hollywood
san jose
