Hi

How can replace all text in tags that starts with

 <td background="Images/top.gif">

and parse the content of (my_own_string_text) variable

String my_own_string_text ='test.gif';

<td background='test.gif'>

Hi, try:

using System.Text.RegularExpressions;

...

string inputData = "your html data here";
string my_own_string_text = "\"test.gif\"";

inputData = Regex.Replace(inputData, "(<td background=)\".+?\"([^>]*>)", "$1" + my_own_string_text + "$2");

This one would be better

inputData = Regex.Replace(inputData, "(<td.*?background=)\".+?\"", "$1" + my_own_string_text);

Hi, use the following, the regex should now match single and double quotes in the input:

...
inputData = Regex.Replace(inputData, "(<td.*?background=)(\"|').+?(\"|')", "$1" + my_own_string_text);

The replacement string just needs to be surrounded with whatever quotes you want to use, for single quotes use:

string my_own_string_text = "'test.gif'";

Hope this helps!
