I'm now trying to make congitive radio with help of a following article.
Configurable SDR Operation for Cognitive Radio Applications using GNU Radio and the Universal Software Radio Peripheral, http://scholar.lib.vt.edu/theses/available/etd-05182007.../01thesis_whole5.pdf

This article proposed XML files for defining SDR and its behaviors. And it said that SDR can use these XML files with XML parser.
However, I have a difficulties on using the parser. The mentioned article doesn't show the part that implementing XML parser.
Is it impossible to use the parser in GRC? Only for a .py file typed manually?

Using XML is outside the scope of GNU Radio. GRC does use XML to define the blocks, but it's not in the same way that you would be using it for your cognitive radio applications. Your best bet is to look into using Expat or Xerces in C/C++ or one of the various Python XML parsers.
