Alas I don't have time to write code for you in some arbitrary language.
However I need to do his from time to time and I use Python.

If you are making a standalone parser for the svg file then you might consider the code below...
If you are writing an extension - search the docs for extension and you will find numerous examples - included with the inkscape package.

I suggest using python and the package called xml.dom.minidom
invoke it like this:

from xml.dom.minidom import parse, parseString
datasource = open(infile)
# get the entire DOM
dom = parse(datasource)

Now the entire dom is loaded and you can traverse the data structure getting/changing whatever you need....

Likewise you can write it out again the same way using:
data = dom.toprettyxml()
f = open(outfile, "w")
f.write(data)

You can get the list of elements matching somename by using functions like:
elements = dom.getElementsByTagName(somename)

and reach inside them using routines like:
for e in elements:
            if e.getAttribute('name') == node_name:
                node = e

many more by looking at the minidom module docs
Best of luck...
