Answer 1

Using PHP:
$var = "1372110902.747405 29245 verbose [paymentserv]: === AUTH: ExternalFundingAnalysisStage was successful (rc:0) ===";
$var = preg_replace("#.*===([^=]+)===.*#i",$1,$var);

Answer 2

Since you didn't specify which language you are using your regex in, any language is presumably a valid response. So, in Perl, you could use the substitution:
s/.*=== (.*) ===.*/$1/;
or the match:
m/=== (.*) ===/;
After the match, $1 will contain the string you wanted to find.
The .* after the second === in the substitute is unnecessary for the sample line of input, but is symmetric with the .* at the beginning of the regex, and symmetry is pleasing. It protects the substitute command from trailing debris; the match doesn't need the protection.

Answer 3

If it's always going to be along the same lines (beginning with AUTH, ending with (rc:#)):
//JavaScript
var str = "1372110902.747405 29245 verbose [paymentserv]: === AUTH: ExternalFundingAnalysisStage was successful (rc:0) ===";
str = str.slice(str.indexOf("AUTH"), str.lastIndexOf(")")+1);
Or with a regex:
str = str.replace(/^.+={3}\s(.+)\s={3}$/,"$1");

Answer 4

for that you also use java regex for detail follow this Tutorial and in your case you can also use sub-string .
Like:
String str ="1372110902.747405 29245 verbose [paymentserv]: === AUTH: ExternalFundingAnalysisStage was successful (rc:0) ===";
String str1=str.subString(58,106);
Stirng str2=str.replace("(","");
Then you get your required answer
