If all you're looking for is specific text like "ccParty" and "Port", couldn't you just grep from the command line?

# grep ccParty filename_goes_here | grep Port | grep DTMF

is probably the simplest way to find the three pieces of text in the same line of a file.

NOTE: If you're on Windows, just replace "grep" with "find" and put double-quotes around the search stings "ccParty", "Port" and "DTMF".
