mxTextTools

[Mike Fletcher]

sets -> [a-zA-Z] in regex/bnf concepts, that is, match any element in the
set

	AllInSet ( "test" ) in "setrmgeneric" --> 3 
	# matches s,e,t from the set of allowed characters

sWordStart -> passes if there are some number of characters (including zero
characters), before the start of the word for which we are searching.

	sWordStart ( "test" ) in "esttest" --> 3
	sWordStart ( "test" ) in "test" --> 0
	WordStart ( "test" ) in "esttest" --> 3
	WordStart ( "test" ) in "test" --> FAIL

Hope this helps,
Mike

Okay, i'm learning mxTextTools on top of the dozen other things i'm doing at
once, at the moment, and have two questions:

With the commands that deal with 'sets', i'm assuming they're talking about
sets returned via the 'set()' function and its similar friends? But what
exactly IS a character set? Why use one instead of a string?

Secondly, 'sWordStart' -- I don't get the description of what it does. It
says it uses a Search Object to perform the required action, which is
fater.. but zero matching characters are allowed.. So, it only passes if
there is NOT a match?

Thanks
