How To Replace Html Tag In Html Editor With Specific String

Feb 9, 2010

anyone knows how to replace a html tag in a string with specific characters:


string s1 = "<span style="italic">inluding <span style="bold">other</span> tags </span>";
string s2 = "<span style="italic">inluding </span><span style="bold">other tags </span>";

i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.

i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.

Web Forms :: How To Replace String Using Regex

Jun 16, 2010

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


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?

C# - Replace String With A Control?

Feb 15, 2010

I have a string with special characters insert in different places. For example:

string myString = "This is a textbox: ##";

I would like to replace the ## with a control (namely, a textbox).

The Replace method only allows the string to be replaced with another string or character (understandably). But what would be the best way to dynamically replace the ## with a control in its position?

I was thinking maybe I could replace it with HTML markup which would be executed, but not quite sure how that would be achieved.

EDIT: To clarify some details. The strings are being retrieved from a database, so I can't use the PlaceHolder control. The user selects a string from a drop-down list. The value of the item is the string with special characters. When the postback occurs from the item selection, I would like to display the string on the site, but replace the special characters with a fully working control (in this case, a textbox)

Find A String And Replace It More Efficiently

Jul 3, 2010

Situation: I have a html file and I need to remove certain sections. For Example: The file contains html:

<div style="padding:10px;">First Name:</div><div style="padding:10px; background-color: gray">random information here</div><div style="padding:10px;">First Name:</div><div style="padding:10px; background-color: gray">random information here</div>

I need to remove all text that starts with "<div style="padding:10px; background-color: gray">" and ends with "</div>" so that the result would be:

<div style="padding:10px;">First Name:</div><div style="padding:10px;">First Name:</div>

I created 2 functions that do this, but I do not this it efficient at all. I have a 40mb file and it takes the program about 2 hours to complete. Is there a more efficient way to do this? Is there a way to use regex? See my code below:.....................

C# - Replace Part Of Text In A Dynamic String

Oct 27, 2010

Let's take this string has an example:

D:/firstdir/Another One/and 2/bla bla bla/media/reports/Darth_Vader_Report.pdf

I want to cut the first part of the path:

D:/firstdir/Another One/and 2/bla bla bla

And replace it with **../**, and keep the second part of the path (media/reports/Darth_Vader_Report.pdf)

If I knew the length or size of it, I could use the Replace or Substring. But since the first part of the string is dynamic, how can I do this?


After StriplingWarrior question, I realized that I could have explained better.

The objective is to replace everything behind /media. The "media" directory is static, and will always be the decisive part of the path.
