I'd guess it probably _is_ doable in Pd, with some tangled use of the [text] (using "search" and "set"). When I do this type of manipulation, it's for mobile, so I'm limited to Objective-C and Java, but if you use Java you could adapt Chris' parser:
https://github.com/chr15m/PdDroidParty/blob/master/src/cx/mccormick/pddroidparty/PdParser.java to get a java data structure representation. Or, potentially simpler, port the parsing logic in that file to python or whatever language you want to use.
