Re: Regular Expression multi-match not as expected

[Loyd Goodbar <loyd@xxxxxxxxxxxxxx>]

Hi Scott,

I think I get it now. In order to process each match, you need to remove the
leftmost portion of the string that was found, and pass the remainder back
into regexec unil no match is found.

I didn't mean to imply that the C runtime regex routines should work the
same as .NET - far from it. I was merely using VB.NET as an alternate
example. I have an application that processes regular data from an automated
process. Part of the data specification is there are exactly 10 lines of
hexadecimal data, and each line begins with a colon. One of the initial
checks for validity is to count the number of colons, using the regex
example posted earlier (regex.matches(...).count). From a syntax standpoint
only, it is shorter and "cleaner" code than looping over the regex. (It may
loop internally, but I didn't have to code it.)

 No worries.
