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've tried many ways to solve the problem that my professor gave me but my knowledge isn't that enough to solve this problem..
Here is the kind of text I want to match via a regular Expression
The id="dgSchedule" is always present in the TAG but its location may differ
The table is span over multiple line/contains white spaces/tabs...
I have the regular expression to match the start and end tag respectively over a single line
[Code]....
Is there any regular expression generator available that can generate me a regular expression based on the text I select and the parameters I specify?
This is slightly different to most questions regarding HTML tags in strings - I want to add HTML!
I'm using a WYSIWYG editor which produces some eratic results. What im looking to do is to check the string it produces and check whether there are any sentences that aren't wrapped in a <p></p> tag. Typical strings could be:
Example 1
<p>Hello, this is string 1</p>
But string two doesnt appear to be in a <p> tag.
Example 2
None of this text is in <p> tags.
Example 3
Single line of text, again not in a <p> tag.
Could this be done using a regular expression?
I was doing some web scraping and i was looking for some div elements with particular class names and markup. This is my objective , i have to extract everything within the div having the class s_specs_box s_box_4 Could someone provide the regular expression in .NET terms (i.e., which can be straight away passed into Regex's constructor)to match one such div (given below)
<div class="s_specs_box s_box_4"><h3>Display</h3><ul><li><strong><span class='s_tooltip_anchor'>Display:</span>
<span class='s_tooltip_content'><p class='s_help'><b>Display</b> - Phone's main display</p></span></strong><ul>
<li class='clear clearfix'><strong><span class='s_tooltip_anchor'>Type:</span>
<span class='s_tooltip_content'><p class='s_help'><b>Type</b> - Refers to the type of the display. There are four major display types: Greyscale, Black&White, LCD:STN-color and LCD:TFT-color</p></span></strong><ul><li>Color</li></ul>
</li><li class='clear clearfix'><strong><span class='s_tooltip_anchor'>Technology:</span>
<span class='s_tooltip_content'><p class='s_help'><b>Technology</b> - Refers to the type of the color displays. There are five major types: LCD, TFT, TFD, STN and OLED</p></span></strong><ul><li>Super AMOLED</li></ul>..............................

How can I fetch the values of each input from the attached HTML using regular expression in c#?
I have the following string:
<div id="mydiv">This is a "div" with quotation marks</div>
I want to use regular expressions to return the following:
<div id='mydiv'>This is a "div" with quotation marks</div>
Notice how the id attribute in the div is now surrounded by apostrophes?
How can I do this with a regular expression?
Edit: I'm not looking for a magic bullet to handle every edge case in every situation. We should all be weary of using regex to parse HTML but, in this particular case and for my particular need, regex IS the solution.
Edit #2: Jens Ameskamp helped to find a solution for me but anyone randomly coming to this page should think long and very hard about using this solution. In my case it works because I am very confident of the type of strings that I'll be dealing with. I know the dangers and the risks and make sure you do to. If you're not sure if you know then it probably indicates that you don't know and shouldn't use this method.

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 write a Regular Expression Validator to allow users to input any number (either positive or negative), except 0. I tried the followings but obviously they failed:
^[1-9-]{1,10}$ <= failed when the 2nd to n-th digit is 0
^d+$ <= failed to treat negative numbers as valid
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.

If i am giving the text

I have custom control for create user. I use RegularExpressionValidator with expression (?=W{1,}){7,} (lentgth min 7 character and must include not less 1 NotAlphaNumeric character) . I test this expression
function GetText(AInputText) {
var VRegExp = new RegExp(/(?=W{1,}){7,}/);
var VResult = VRegExp.test(AInputText);
return VResult;
}
it's work. But RegularExpressionValidator doesn't accept this expression for input - 1234567! or 12345qwer!
This expression is to check number > 1
^[1-9]+[0-9]*$
what is the expression to check if it's greater than a given value, say "99" ? what about a value less than, 99?
Update:
I'm using ASP.NET validation control.
I currently have this regular expression for a whole number with optional decimal to 2 places.
I need to change it so that the number has to be greater than 1.
Code:
[0-9]+(.[0-9][0-9]?)?
