I am working on a web application in which I am getting a string from database and breaking it to use it. This is the string: string str = "DB1031229";
But sometimes I am not getting proper results. I need to break it in :
DB
10
1229
You can notice that I have not included 3 in that. I dont need that.
i have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.

I am really struggling with this! Using the regular expression validator I created an expression, thus ":" to show an error message if the user tries to enter in a name that contains a colon.

I am using a regex to detect forum tags within posts, such as "[quote]text[/quote]" and then replace them with HTML formatting. I posted a question Forum tags. What is the best way to implement them? about a problem with nested tags.
I need this regex modified
string regex = @"[([^=]+)[=x22']*(S*?)['x22]*](.+?)[/(1)]";
Right now this matches an opening and closing tag, with match groups for the tag name, the tag content, and an optional value like the value after the equals in this forum tag [url=www.google.com]click me[/url].
What I need is for the expression to match the opening tag OR the closing tag and have a match group containing the tag name (including the '/' for the closing tag). I then want to iterate through them sort of like this:
Dictionary<string, int> tagCollection = new Dictionary<string, int>();
inputString = Regex.Replace(inputString, @"expression I'm asking for here",
match =>
{
[Code]....
So now, each tag is appended with a number and I could use the original regex to perform the tag functions and properly handle nested tags as separate tags.
I have one field in database Mobile No.
In that I want to put validation which accepts "+" and numbers that is not more then 15.
And in that "+" should at the first place in value.
I got this code from a regular expression library to get the src of the image found in a given input. However I can't get it to work because the double quotes(") in the regular expression is closing the string under the second parameter for the .Match function. I tried changing double quotes(") to " but it doesn't work too.
[Code]....
