I am looking for a regular expression for c# asp.net 3.5 that will fail if there are ever any double spaces in a sentence or group of words.
the cat chased the dog = true the cat chased the dog = false (doubles spaces occur at random intervals)
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.

How can I make this regex not accept spaces?: [0-9a-zA-Z' ']{3,}
Everything I'm reading says to put a * or a + after the [] , but I get an invalid expression error when I do. The end result I'm looking for is a string of letters and numbers only - no spaces inbetween.
am using this function to remove whitespaces at html output. i had to put if else otherwise page was giving error afterasynchronous postbacks. now it works fine.is it possible to make it work also after asynchronous postbacks ?also is it possible to make this regex function also removes new lines ?like how google doesthere is no line at their source codes

I'm trying to complete a regular expression that will pull out matches based on their opening and closing characters, the closest I've gotten is
^([[)[a-zA-Z.-_]+(]])
Which will match a string such as "[[word1]]" and bring me back all the matches if there is more than one, The problem is I want it to pick up matchs where there may be a space in so for example "[[word1 word2]]", now this will work if I add a space into my pattern above however this pops up a problem that it will only get one match for my entire string so for example if I have a string
"Hi [[Title]] [[Name]] [[surname]], How are you"
then the match will be "[[Title]] [[Name]] [[surname]]" rather than 3 matches "[[Title]]", "[[Name]]", "[[surname]]". I'm sure I'm just a char or two away in the Regex but I'm stuck, How can I make it return the 3 matches.
I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*
I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>

I am trying to find two lots of expressions on a page and extract them. I currently can do one and extract the text from between certain tags with the following code:
Regex r = new Regex("<tag>([^<]*)</tag>");
but im trying to do two lots... for example...:
Regex r = new Regex("<tag>([^<]*)</tag>" + "<ad ahs="e">([^<]*)<ad ahs=h>");
I have to filter user input to on my web ASP.NET page:
<asp:TextBox runat="server" ID="recipientBankIDTextBox" MaxLength="11" />
<asp:RegularExpressionValidator runat="server" ValidationExpression="?" ControlToValidate="recipientBankIDTextBox" ErrorMessage="*" />
As far is I know SWIFT code must contain 5 or 6 letters and other symbols up to total length 11 are alphanumeric.
How to implement such rule properly? TIO
