Flatten A Group String Pattern?

[EdwardBrian]

I'm sure this is an easy one, just not finding it. I'd like to take a string like "0-6:2 ,10" and expand that into a flattened list: "0 2 4 6 10"

I found:

//OP_Node.h
// The following function will take a standard pattern and expand
00386	 // all the groups out of the pattern, leaving a simple pattern
00387	 // in the result.
00388	 bool				 expandGroupPattern(const char *pattern,
00389											 UT_String &result,
00390											 bool expandToFullPaths = false);

I didn't seem to do anything other then just return the same pattern to me. Maybe this is more for group name patterns.

Thanks
