JSON, Unserialize, and XML (Web Stuff)

[Gunner]

I am working on a tool to help me with some things.  What I do is do a POST to a few websites and they return information in one of 4 ways: JSON, PHP Serialized, XML, or Pipe delimited.  Only one returns info with pipes... the others use one of the other three and I decided what they return.  My question is:  Are there any asm libs or code that will parse XML, JSON or PHP serialized info?  JSON seems easy enough to write a parser for, serialized data and xml is a little more work.  Maybe someone has something in their librarys?
