Recalling from my Computer Science studies compiler construction seminar many
years ago,
the first step was 'lexical analysis', which transforms the verbose input text
into an intermediate
form (tokens) and doing some syntax checking on elements (i.e. integer number
conversion, etc.).
The result of this phase is passed to the 'parser', which checks for syntactical
correctness of the
whole input. The final phase would be 'code generation', or in an XML file
transformation the
generation of the target format. Also the well known tools: lex and yacc follow
this model.
Using the word 'parse' here seems sloppy, but acceptable use - transformation
seems a better
term in my view.

Computer Science: To analyze or separate (input, for example) into more easily
processed components.
Root: from Latin porti, a part, according to each part,
It means to cut into pieces. To convert one format into another, you must first
cut the input message (source format) into its individual fields and then put
them each into their proper places in the target format. Thus "parsing" is
really the first stage of mapping/translating to another format.
