Regular Expressions Multiple Lines

[Jeremy R. Harner]

I've been trying to figure out this for many hours now. I have a file
that is in the following format:

Game #xxxxxxxxx
stuff
stuff
stuff
stuff
stuff
-----------------------------
Game #xxxxxxxxx
stuff
stuff
stuff
-----------------------------
Game #xxxxxxxxx
stuff
stuff
stuff
stuff
-----------------------------

Here is my code:

//Match from 'Game # to ----------------------------- so includes all
the stuff.
string sRegex = @"Game\s#\.+-----------------------------";

MatchCollection theMatches = Regex.Matches(sText, sRegex,
RegexOptions.Singleline);

where, sText is the above text.

I then want to do:

foreach( Match m in theMatches)
{
string s = m.ToString();
//Do other text parsing
}

I want there to be three matches. So that the string s contains
everything from Game to the line of hyphens (------------------). But
this regex finds only one match and it is the entire string all three
segments. Any ideas on what a regular expression that would work.

..+

matches as many characters as possible. Try using a non-greedy match
instead:

..+?

and dont forget to use the RegexOptions.Multiline flag so that [.*] will
match newline characters

I could be wrong, but I thought I wanted the RegexOption.Singleline
set so .+ will match every line. What would having the
RegexOption.Multiline option do. The documentation says:

Singleline Specifies single-line mode.

Changes the meaning of the dot (.) so it matches every character
(instead of every character except\n).

I tried this regular expression:

@"Game\s#.*?--------------" but it still returns no matches. Again i
have the SingleLine option set.

[Eric Newton]

because the . in SingleLine mode will NOT match newline characters... what
i'm saying is it seems like you actually DO want the Multiline set...

Are you sure you output each matched string because this should work fine.
The syntax is good and you use the SingleLine option, which is a must.

(Multiline option isn't required, it changes the behaviour of $^ so that it
matches every line instead of the whole text)

HTH
greetings

have the SingleLine option set.
