That range matches all the characters in the ascii chart except the control
characters. Same as saying give me all the Ascii characters from Ascii 32
(space) to Ascii 126 (_). I thought it was a bit more restrictive than the
dot operator.
In the [\w -~], the -w is actually redundant since \w stands for
[a-zA-Z0-9].
Another improvement would be to account for variable spacers using
reFindNoCase("<a +[ -~]+productID=[ -~]+</a>",inputString, pos).
As far as I know, greediness is not restricted to CF but can be found in any
regular expression. From what I've heard CF8 deals with regexp differently
than CF7. For example, I think CF8 will return an array of matches.
In looking at this again, I'd say it is greedy because of the [ -~]+ pattern
(similar to using .+) . I think using reFindNoCase("<a
+?[ -~]+?productID=[ -~]+?</a>",inputString, pos) will force minimal
matching but I'd have to run some tests with it to be sure.
Any regexp experts care to weigh in? I don't use them enough to be an
authority and would like to learn more....
