I have this pattern: @"\s*//\$\$\s*Targets: \s*([\s,\w]+)"
to match this line: //$$Targets: thing, thing+
When I get a match, the first Group (index 1, not 0) has: "thing, thing" -
it drops the plus ('+'). Now, I don't know the plus will be there,
everything after "Targets:" is variable and will change so I can't simply
add an explicit check for it.
What trick is there to get the special characters returned in the groups?
Thanks for reading,

Well, you've currently said you want to match whitespace characters,
commas, and word characters. Any extra characters you want to capture
need to be in the [...] part. So, to get + as well, you'd need:
[\s,\w\+]
To you just want to match to the end of the line though? If so, just
use (.+) instead of ([\s,\w]+).
(You might want to use the $ "end-of-string" assertion, depending on
what other options you have, such as multi-line.)

Jon, perfect, thank you! Regex is sooo much faster than string comparison
parsing, I can't believe it.

Well, there are times that it's faster, and there are plenty of times
that it's slower. For instance, if a matching string is always just
//$$Targets: (stuff)
and you want to get (stuff) - all the way to the end of the string -
then using IndexOf and Substring would be simpler and almost certainly
faster.

Hi,
string test="dit is een test";
bool bMatch = Regex.IsMatch( test, "^(|)*$" );
after executing, the bMatch is false
The pattern is not optimized and seems a little stupid. But for large regex
expressions using smaller strings to build it, the same problem could arise.

Hi All,
I'm trying to split a string on every character. The string happens to be a
representation of a hex number. So, my regex expression is ().
Seems simple, but for some reason, I'm not getting the results I expect.
Dim SA as string()
Dim S as string
S="FBE"

Hi,
I am using the following pattern:
"\\b" + MySttring + "\\b"
If MyString is "one", this should pick up whole words like "one".
The problem is, it will pick up also the word: "one.two" How should I modify
the patter to pickup only "one"?
