Hi I have following line of code
{
.....(here i can have anything, numbers, string special characters
...."hello"
}
I need to know Regex pattern which finds the above pattern for me, where string starts from { and then some text, then a keyword like "hello" and then }.
Please help
So i had
function test(a,b,c){
}
function test2(c,a,d){
if(a > 0){
alert('test');
}
and i got this expression function\s+(\S+)\s*\((.|\n)*?\)\s*{
which gives me function test(a,b,c)
and
function test2(c,a,d)
I want a regular expression which gives me function when it finds a keyword like 'test' inside that function.
Makes sense?

I don't know c# but the regex like (with .
matching linefeed):
.*\bfunction\b.+?\bhello\b.+?\}
should do the job.
Explanation:
The regular expression:
(?s-imx:.*\bfunction\b.+?\bhello\b.+?\})
matches as follows:
NODE EXPLANATION
----------------------------------------------------------------------
(?s-imx: group, but do not capture (with . matching
\n) (case-sensitive) (with ^ and $ matching
normally) (matching whitespace and #
normally):
----------------------------------------------------------------------
.* any character (0 or more times (matching
the most amount possible))
----------------------------------------------------------------------
\b the boundary between a word char (\w) and
something that is not a word char
----------------------------------------------------------------------
function 'function'
----------------------------------------------------------------------
\b the boundary between a word char (\w) and
something that is not a word char
----------------------------------------------------------------------
.+? any character (1 or more times (matching
the least amount possible))
----------------------------------------------------------------------
\b the boundary between a word char (\w) and
something that is not a word char
----------------------------------------------------------------------
hello 'hello'
----------------------------------------------------------------------
\b the boundary between a word char (\w) and
something that is not a word char
----------------------------------------------------------------------
.+? any character (1 or more times (matching
the least amount possible))
----------------------------------------------------------------------
\} '}'
----------------------------------------------------------------------
) end of grouping
----------------------------------------------------------------------

How about this:
MatchCollection matches = Regex.Matches(YourText, @"\{[^}]*""hello"".\}", RegexOptions.Multiline);
foreach (Match match in matches)
{
foreach (Capture capture in match.Captures)
{
Console.WriteLine(capture.Value);
}
