I'm testing out a CMS I've built in ASP.NET and I'm having issues validating a form textarea with a regular expression.
I've used a ReguarExpressionValidator control to make sure a maximum of 4000 characters are entered but have realised I'm not including line breaks in the regular expression and can't figure out how to include them?
I would like to know what the expression for "letters only" is for my asp.net web application. I tried ^[A-Za-z] but it does not work I would also like a regular expression for "numbers only except "-"
I'm trying to use a RegularexpressionValidator to match an IP address (with possible wildcards) for an IP filtering system.I'm using the following Regex:
Which works fine when running it in LINQPad with Regex.Matches, but doesn't seem to work when I'm using the validator.Does anyone have a suggestion as to either a better Regex or why it would work in test but not in situ?
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>..............................
i have a textbox in my web form and i want to input any word with any character. so, only i want to check length of textbox less than 200 character. how can i do it with regular expression? and if i want to block some character how can i do it?
I Would like to write a custom regular expression where the format is like XYZ-ABC-001 where XYZ is fixed, ABC is variable (it can be any three characters between A-Z )001 is variable (it can be any number between 0-9)
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. What I am getting is the error message showing even when there is no colon (:) in the string. What am I doing wrong?
