Im trying to make some BBCode-translation from textarea, but im stuck on translate list to html. I have this fo Bold text:
[Code]....
But how can i do if i want to translate this:
[Code]....
I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.

My book "Murachs ASP.NET 3.5 With C#2008" tells me how to verify that it is:
any number
not any number
any word character(abc' and 123's)
not any word character
characters in range
everything you could possibly want to know except what I woudl consider to be the most obvios.
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

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?
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..

Any one show me way to get each row in above table and push it into string array ?
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.
In the "Regular Expression Editor" dialog in VS 2008 ( or 2005 for this matter ) ,
there is a list of "standard expressions" like :
"French phone number" , "French postal code" etc..
And of course there is an option to select a "Custom" and then enter your own regular expression.
Well.. I want to add a predefined expressions to that list . Like : "Israeli phone number" .
I don't want to enter it every time by selecting a custom value .
I want my developers in the team available items for them to choose.
Anyone knows how to alter that list ?
I've found some question about it on the web - and the answer given is that it's not possible .
I'm working with an MVC1.0 web app and I've found a bit of an odd anomaly.
I have a search box on the first page (normal text box) and the input from this is passed through to the ViewData and on to the second page.
On the second page, I render a TextArea with this search input text from the ViewData.
Eg:
[Code]....
The problem is, there is an extra line break in the TextArea, just above the original text.
Stranger still is that if I now submit this page and the view is reloaded (after validation fails) - the original string of text has been trimmed and has no line breaks, but the TextArea now has 2 line breaks above the original text.
This can be repeated - every time the page reloads it has another line break.
It's driving me insane - does anyone have an idea on how to fix this?
FYI, you can check it out yourself - on your mobile phone, browse to [URL], punch something in the search box and hit search. You'll notice one line break added the first time the page loads. Then just hit "Find Best Offer" without entering a budget or selecting a category, and you'll see what I mean about the additional line breaks.
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>

View 3 RepliesI have a regular expression validation set on text box. I have a grid on the same page with edit and delete buttons. In some cases I don't want the regular expression to fire. For example, I have a scenario where the text box will be disabled but I can still enter data in to the grid and modify it, but the regular expression fires when I modify the grid and the changes in the grid are not processed.how can I stop the validation when I am working on grid. I can see a property causes validation for button to stop validation but don't know how can I stop for the grid.
