well.. the first approach i've taken are arrays of functions who handle given
tags at certain levels, each handler has another array of handlers and so on.
this results in large amounts of code.
the problem is that i'm dealing with tags containing attributes, and i want to
make the parser as general as possible.  if i only dealt with tags (no attribu-
tes) (as in <TAG attribute="value">), i could then make a tree of tags, go
down it, and write handler functions only for the leaves.  but because
of the attributes, such an approach gets very complicated.

i am wondering whether it makes any sense to use XML for my task.  which is
inter-daemon communication.  a php3 script collects data from the user,
converts it to XML and sends commands to the daemon i'm writing.  is this
good usage for XML?  or is there some easier way to handle this, without all
the parsing fuss?

could You point me to a piece of software doing a similiar thing as mine?
