how to split content.rdf.u8 and structure.rdf.u8

hi
I want to use Games and Sports category.I have downloaded both filed "content.rdf.u8" and "structure.rdf.u8" but it take a lot of time to parse.is there any way to split these files by catergory i.e Games category in one file and Sports in other file.how can i break\split these large files.
thanks
Usman

You could use JODPIE to parse such RDF files and import only what you really need into a database like MySQL or PostgreSQL. For Games and Sports category JODPIE should be able to finish both parsing and importing in about five minutes.
