Only one function, really: FooParse. Accepts an XML file to pass to
XML::Simple and returns an array of objects read from the file. I may
want a second function FooWrite later.

Thanks, it's working now.

I've attached the working module. Basically, I'm trying to make it
trivial to parse a particular (generic) XML format that is used by a
variety of my programs by hiding all the XML stuff and just providing
an array of objects where the object members are exact matches for the
object members in the original C source code and in the XML itself.
Objects belong to pilot-qof, cashutil / gnucash and gpe-expenses and
more will be added later. The snippet in the module pod content does a
simple calculation of the total number of miles claimed from a
pilot-qof XML file. pilot-qof provides the query interface to isolate
the expenses on a variety of criteria (client, date range etc.) and the
script just provides a useful summary output. Subsequent scripts will
collate data from pilot-qof into a gnucash style invoice.

The XML format is prescribed by the XML schema within the QOF backend
code - applications linked against QOF provide their object
definitions, the library creates the XML format for those objects from
the definition and the script parses the XML format to provide an array
where members are described by the same definition.
