Hello all,
I'm experimenting with moving to XML for some of my data files, a typical
example is placed at the bottom of this message. It is attractive since there
are lots of XML editors out there which means that users can make minor changes
to the data file without running the programme. The programme reads in some
experimental data and generates an SVG file for presentation quality graphics -
I have not bothered to write the same graphic within Rev. If you want to see
the program it is at http://www.liv.ac.uk/pfg/Downloads/PeptideMapper.zip but
you'd probably need to be a bit of a biochemist to make sense of it! It is my
first real Rev program.
What I'm not clear about is how I use Rev's XML functions to read in such a
file, and populate my program's variables with the various values. It seems as
though I would need to still write lots of nested loops, which suggests I'm
missing a trick. Can anyone point me at some demonstration material that would
help me generate an XML parser.
BTW, the XML file below was created in a text editor. I will also need to learn
how to write this file within my programme!
Thanks in advance
Rob
