Well, I'm not surprised - your regex doesn't match your input...
Your class delimiters are not the same - double quote and single quote are not the same character; "onload" is not the same as "önload"; there is a semicolon at the end of "img_onload(this);" instead of after the double quote, and so forth.

Seriously, I wouldn't parse HTML with a regex: it's a silly idea. Instead try using a HTML reader which will process the input as HTML and provide lines, attributes, and so forth in a much mopre friendly and reliable way.

A quick google will find you loads of them here: https://www.google.co.uk/search?q=HTML+reader+codeproject&oq=HTML+reader+codeproject&aqs=chrome..69i57j0l5.6613j0j7&sourceid=chrome&espv=210&es_sm=93&ie=UTF-8[^]

Solution 2

You can go for jQuery also. For example you can check it using the code snippet:

C#

alert($("#visible-image-small").attr("src"));

Solution 3

Try this

C#

int srcindex = s.IndexOf("src=") -4;
           int onloadindex = s.IndexOf("onload=");
           int length = onloadindex - srcindex -2;
           string output = s.Substring(srcindex, length);
