I think you need to use two backslashes instead of one.
Thanks, that's great, it works. However a simple match of this pattern against "class([1,0,0,0],\"METABOLISM\")." gives me ["1,0,0,0","","","","","","","","","","","","","","","","","","","","","","","","","","","",""] ie the right answer, and 28 other empty answers. The documentation says "Note that there may be more components in the returned list than were in the pattern, and that any component which either matched the empty string or wasn't matched at all (because it was part of an optional part of the pattern), will be empty." Does this mean I had 28 matches with the empty string? Why are they returned? Will I always have to filter all these null strings out of every result? Will the result I want always be first?
