I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.
I was trying to follow this tutorial on msdn, but it doesn't quite fit perfectly with my problem:
I need a regex or any other solution to replace an id in the middle of a url (not in querystring). url example - http://localhost:1876/category/6?sortBy=asc&orderBy=Popular
replace - category/6 with category/anotherID - routing used - routes.MapRoute( "categories", "category/{categoryID}/{categoryName}", new { controller = "Search", action = "SearchResults", categoryID = "", categoryName = "" } );
I need regex in c sharp to display SSN in the format of xxx-xx-6789. i.e 123456789 should be displayed as xxx-xx-6789 in a textfield. The code I am using write now is
i m using a regex to not allow certain characters, the below code works fine for certain html tags but not for all for i dont want the user to enter html tags for eg if i enter <nitin/> it allows but i dont want this to happen for other html tags it does not allow
!@#$%^&*()+=[]\';,/{}|":<>? or !@#$%^&*()+=[]\';,/{}|":<>/>?
with a regex that would replace the following. The only thing that would remain the same is the div tags, the id's and classes could change and so could the content.
<div id="nav" class="whatever">Content is whatever</div>
The code works, but I need to include some exceptions to the replace - e.g. I will not replace anything i an img-, li- and a-tag (including link-text and attributes like href and title) but still allow replacements in p-, td- and div-tags.
How do I solve the problem below? I'm creating a simple content management system, where there is a HTML template with specific markup that denotes where content should be:
Separate from this, there is content in a database field that looks a little like this:
<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test text<!-- #EndEditable -->
As you can guess I need to merge the two, that is, replacing
<!-- #Editable "Body1" -->
with: This is Test Text. I've begun the code here. But I'm having problems using the Regex Replace function that should be located at the very bottom of that For/Each.
//Html Template string html = "<html><head></head><body><!-- #Editable "Body1" --><p>etc etc</p><!-- #Editable "Extra" --></body></html>"; //Regions that need to be put in the Html Template string regions = "<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test #EndEditable -->"; //Create a Regex to only extract what's between the 'Body' tag Regex oRegex = new Regex("<body.*?>(.*?)</body>", RegexOptions.Multiline); //Get only the 'Body' of the html template string body = oRegex.Match(html).Groups[1].Value.ToString(); // Regex to find sections inside the 'Body' that need replacing with what's in the string 'regions' Regex oRegex1 = new Regex("<!-- #Editable "(.*?)"[^>]*>",RegexOptions.Multiline); MatchCollection matches = oRegex1.Matches(body); // Locate section titles i.e. Body1, Extra foreach (Match match in matches) { string title = oRegex1.Match(match.ToString()).Groups[1].ToString(); Regex oRegex2 = new Regex("<!-- #BeginEditable "" + title + ""[^>]*>(.*?)<!-- #EndEditable [^>]*>", RegexOptions.Multiline); // // // Replace the 'Body' sections with whats in the 'regions' string cross referencing the titles i.e. Body1, Extra // // // }

Regex r = new Regex(@"[^$]"); string Contents = txtRegEx.Text.Trim(); MatchCollection ImageCollection = r.Matches(Contents);
string str = "LDAP://company.com/OU=MyOU1 Control,DC=MyCompany,DC=com"; Regex regex = new Regex("OU=\w+"); var result = regex.Matches(str); var strList = new List<string>(); foreach (var item in result) { strList.Add(item.ToString().Remove(0,3)); } Console.WriteLine(string.Join("/",strList));
the result i am getting is "MyOU1" instead of getting "MyOU1 Control"
I want a text box which will accept CSV values and the values can be any time of a day,i.e.,in one text box I can enter multiple clock times,separated by comma.Hour,Minutes will be separated by :.Second no required
If a.m. or p.m. can be associated it would be great[0-12 basis], otherwise 0-24 basis will be fine.
I'm looking for a regex that will allow Alpha Numeric and most all special characters except white space. It should be usable in c#. It would be nice if .net supported posix style but I can't seem to get it to work.
I am trying create a Regex-based replacement for an article to automatically convert embedded references (many of them) in posts into the appropriate link and title format.
For example, given this:
I have already blogged about this topic ((MY TOPIC ID: "2324" "a number of times")) before. And I have also covered ((MY TOPIC ID: "777" "similar topics")) in the past.
... I want to get this:
I have already blogged about this topic <a href='/post/2324'>a number of times</a> before. And I have also covered <a href='/post/777'>similar topics</a> in the past.
I currently have this:
/* Does not work */ public static string ReplaceArticleTextWithProductLinks(string input) { string pattern = "\(\(MY TOPIC ID: \".*?\" \".*?\"\)\)"; string replacement = "<a href='/post/$1'>$2</a>"; return Regex.Replace(input, pattern, replacement); }
But it seems to return lines that contain <a href='/post/'></a> without appending matches instead of $1 and $2.
Question: What is the easiest way to do convert the string #1 above to string #2 above?
