Long time listener, first time caller.

I'm trying to do some very dynamic form work and have run into a problem
that I don't quite know about.

I have information in an XML file that I use to populate the form
(checkboxes and text boxes). The names of those objects come from the
information in the XML file. Once the form is submitted I need to iterate
over all the $_POST information and update data in the XML file according to
what was checked and entered into the check/text boxes. 

So far I've gotten stuck on $_POST['$varname'] always being empty. ($varname
will change every iteration of a loop, so there's some nested goodness too)
Using var_dump($_POST) shows me that in fact the $varname variable is there
and even using strcmp on a string that is exactly the same as what var_dump
tells me is there doesn't work. 

The XML datafile changes daily, so I can't count on fields being there or
not, or being in the same place in the file. 

Any thoughts from the php gurus out there?

Thanks,

-Jason
