will be helpful for those in need Not exactly sure what you are asking: do you want to return a match only if "foo" and "bar" are both in the document? If so, then
(?>.*foo.*bar)|(?>.*bar.*foo) 
        string text = @"blah blah bar foo bar";
        string pattern = @"(?>.*foo.*bar)|(?>.*bar.*foo)";
        Match match = new Regex(pattern, RegexOptions.Singleline).Match(text);
        if (match.Success)
        {
            // do something
        }
((?<CCNum>4\d{3}[ -]?(\d{4}[ -]?){2}\d{4}).*Bar)|(.*Bar.*(?<CCNum>4\d{3}[ -]?(\d{4}[ -]?){2}\d{4}))
        string text = @"Bar 4111-1111 1111 1111";
        string pattern = @"((?<CCNum>4\d{3}[ -]?(\d{4}[ -]?){2}\d{4}).*Bar)|(.*Bar.*(?<CCNum>4\d{3}[ -]?(\d{4}[ -]?){2}\d{4}))";
        long CCNum;
        Match match = new Regex(pattern, RegexOptions.Singleline).Match(text);
        if (match.Success)
        {
            if (Int64.TryParse (match.Groups["CCNum"].Value.Replace(" ", "").Replace("-",""),out CCNum));
            {
                // here is your clean CC Number
            }


        }

Create a program that inputs a regular expression and outputs strings that satisfy that regular expression


Tag : regex , By : Trevor Cortez

Hope that helps Well a regex is convertible to a DFA which can be thought of as a graph. To generate a string given this DFA-graph you'd just find a path from a start state to an end state. You'd just have to think about how you want to handle cycles (Maybe traverse every cycle at least once to get a sampling? n times?), but I don't see why it wouldn't work.

Find all matching strings of a regular expression (without + and * operator)

With these it helps I think this Java library will help you with this http://code.google.com/p/xeger/ and since it is Java, it would also run on Linux.

I wish this helpful for you I'm developing an HTML parser. Specifically, I'm working on a module which parses PHP errors from the returned HTML. Here's an example:
/.*(Fatal error).+(on line).*/

Regular Expression to identify all camel cased strings in a document


Tag : javascript , By : ianium

this will help This identifies all occurrences of "strict" camel case (only letters). Whether they start with _ or $ or foofoo doesn't matter.
[a-z]+[A-Z][a-zA-Z]*
[a-z]\w*?[A-Z]\w*
[a-z][\w$]*[A-Z][\w$]*

How to use Regular expression in perl if both regular expression and strings are variables


Tag : regex , By : user177910

fixed the issue. Will look into that further The double-quotes that you use interpolate -- they first evaluate what's inside them (variables, escapes, etc) and return a string built with evaluations' results and remaining literals. See Gory details of parsing quoting constructs for an illuminating discussion, with lots of detail.
And your example string happens to have a $/ there, which is one of Perl's global variables (see perlvar) so $pattern is different than expected; print it to see. (In this case the / is erroneous as discussed below but the point stands.)
my $pattern = q(^current.*$);
my $pattern = qr/^current.*$/;
