Yes, you (do something, but don't parse) RDF and create some other format. 
Format transformations surely don't require parsing. My objection is that 
what you are doing to create that other format is not parsing; it's rather 
just a text to tree transformation that is deterministic (really a very 
simple state machine). Calling that "parsing" trivializes the much more 
complex languages that parsers can make sense of. None of the on-line 
languages (with the possible exception of CSS) require any parsing; SGML was 
designed to not require parsing and all of these other formats kept the 
basic design of SGML.
