I would like to conditionally remove a block of text between specifed start and stop delimiters. The code below does not work, but hopefully it suggests enough of what I am trying to accomplish.

I need to replace <span> entries in a string to legacy html code because it's going to be used in a report for Crystal Reports. <b> works with Crystal, but the<span>'s do not.
Here's the string which I'm trying to replace: <span style="font-weight: bold">%THIS CAN BE ANY TEXT%</span>. I want to replace it to
<b>%THIS CAN BE ANY TEXT%</b>.

I am getting taggings like the following in a string
<color> vocation </color>
<color> elation </color>
<color> sage </color>
you can notice that each tagging differs only in the wordings
vocation
elation
sage
But i want to write a code some thing like this
Regex.Replace(userAx, "<color> vocation </color>",
"<color> </color>"
so that the resulting output does not contain words at the centre.In the above code instead of giving the word vocation exclusively, i have to mention some pattern, so that it will replace all the words instead of doing it for first sentence only.How to modify my code?
writing the regex pattern for the below case ? I do not want to use string.replace so using Regex.Replace

I have a textbox where I accept multiple email ids separated by a comma. I then split it in my code-behind. If an email id is invalid, I change the background of it using Regex.replace, like this:
Regex.Replace(InputTxt, Search_Str, StartTag & "$1" & EndTag, RegexOptions.IgnoreCase)
My start and end tags are definned as:
"<Span class=highlight>" and "</span>"and my CSS is defined
as:.highlight { text-decoration: none; color:black; background:yellow;}This doesn't work.
I'm trying to replace some code generated by the AJAX Control Toolkit HTMLEditor from the XHTML standard to legacy code; <span style=*> to <b>, <u>, <i>, etc. This needs to be done because Crystal Reports doesn't understand the <span style=*> and needs the legacy items.
This is the code being generated by the HTMLEditor:
[Code]....
Is Regex.Replace the best way to replace these items? I need to keep the text between the opening and closing statements as well as ensure the proper formatting to the text so doing just ReplacementText.Replace will not work. I've tried a number of different things to try and get Regex.Replace working properly but keep having different issues and different things happen. But why it's not using the the closing span for the bold statement but using the closing span for the italics is beyond me.
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 try to replace [h2] to <h2> I use this coding:
string o = "<h2>test</h2>";
o = Regex.Replace(o, "[h2]", "<h2>");
o = Regex.Replace(o, "[/h2]", "</h2>");
But the result after the first regex is:
[<h2><h2>]test[/<h2><h2>]
So that is not what i want.
After the first 1, he should make:
<h2>test[/h2]
Whats wrong?
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>
string lNewHTML = Regex.Replace(lOldHTML, "(word1|word2|word3)", "<a href="page.aspx#$1">$1</a>", RegexOptions.IgnoreCase);
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:
<html><head></head><body><!-- #Editable "Body1" --><p>etc etc</p><!-- #Editable "Extra" --></body></html>
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
//
//

I am working on ASP.NET (C#) application. I want to change number decimal figure with comma(,) where i have dot(.) using regular expression.
For example:
Price= 100,00.56
As this international rule of representing numeric values but I Sweden they have different ways for numbers Like
Price= 100.00,56
So i want to change dot(.) into comma(,) and comma(,) into dot(.) using RegEx.
I would like to use a regular expression in C# to turn any two or more spaces into non-breaking spaces. I would like to leave single spaces alone.
Sample Sample
Would produce
Sample Sample
But
Sample Sample
Wouldn't be affected.
How can I replace Html inside pre tag? I would prefer to do that with Regex

I want to change the way my blogs are displayed on my website. I currently use a seperate table in SQL to hold them and do a loop and replace.
All I really need to do is have a code that can be translated into real HTML in the blog code. I need to know the image name and the css class.
I was thinking is it possible to have somthing like this in a blog stored in the DB
<img L 1234.jpg> and use regex to match it and change it ton<img src="1234.jpg class="imgleft">
I know it looks like well why not just use the long code and not use regex, but I have a method that gets in the image path from the image name with padding. So in this case the image path would be 000/000/001/234/1234.jpg
I would have more then one occurance in the original string so would need to either somehow replace them all at once or use the regex to loop through untle they have all be matched
is something like this possible or do I need a different approach
i'm trying to find all the anchor tags and appending the href value with a variable.
for example
<a href="/page.aspx">link</a> will become <a href="/page.aspx?id=2">
<A hRef='http://www.google.com'><img src='pic.jpg'></a> will become <A hRef='http://www.google.com?id=2'><img src='pic.jpg'></a>
I'm able to match all the anchor tags and href values using regex, then i manually replace the values using string.replace, however i dont think its the efficient way to do this.Is there a solution where i can use something like regex.replace(html,newurlvalue)

View 6 RepliesHow to use pattern replacement in the RTF?. For example you can add a placeholder like {USER_FIRST_NAME} in the RTF document. When the user clicks the download button, your application can take the information from the database and replace every instance of {USER_FIRST_NAME} with the data from the database....
View 1 RepliesI have defined this in the web.config of a subdirectory
<namespaces>
<remove namespace="App"/>
<add namespace="Tom"/>
</namespaces>
App is imported in the parent web.config file, Tom and App have classes with the same names.To avoid errors resulting from ambiguous class names I removed the App namespace from the sub-directory where the Tom namespace is used.
However the namespace App is still imported on content pages that have a master page outside the Tom directory. This causes the aforementioned errors.Here is my dir structure
-Root Directory
--Default.master
--web.config (App is added in web.config)
--Tom Sub-diretory
---web.config (App is removed in web.config)
---Content page that uses Default.master (Here is the problem)
---Page without master (Works OK)
I have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?

I want to find a substring (email) in a large text using Regex.
just want to return the first valid email that is found from the input text:
example:
string inputString = "Our email is myname@ourcompany.com.
desired output: myname@ourcompany.com
this is the Regex pattern i've used: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$
- is this pattern correct?
Code:
private static void DumpHRefs(string inputString)
{
Match m;
string HRefPattern = @"^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$";
m = Regex.Match(inputString, HRefPattern,
RegexOptions.IgnoreCase | RegexOptions.Compiled);
while (m.Success)
{
Console.WriteLine("Found email " + m.Groups[1] + " at ".......
