Best modern text parsing? AKA When to use Lex and Yacc?

Question

I have input blocks of text with commands and arguments, one per line, for example

XYZ ARG1,ARG2,ARG3,...,ARGN

And I want to check that the arguments for are XYZwell-formed for this particular command and execute the correct block of code, if any. There is something like ~ 100 commands, some of which have a variable number of arguments, different relationships (i.e. if a command was called XYZ, then I also need to call the command ABC).

There are also commands:

COMMAND
XYZ ARG1
BEF ARG1 ARG2
ENDCOMMAND

It is important that the text is contained in COMMANDand ENDCOMMAND.

Usually for something like this I would use Lex and Yacc rather than regex's, but is there anything more modern? The code is written in C #. Is there anything on MSDN that does this, and not the old C Lex and Yacc school?
