内容如上，我想查找其文字列“200” 的注释 title="bbox 28 27 76 52" 这一部分应该怎么找好呢？
如果正则求正则表达式~~（不能与"bbox 108 27 200 52" 里面的200 混淆） HTML 正则类

[解决办法]

string tempStr = File.ReadAllText(@"C:\Users\myx\Desktop\Test.txt", Encoding.GetEncoding("GB2312"));//读取txt
            string pattern = @"<span[^>]*?class=(['""]?)ocrx_word\1[^>]*?title=(['""]?)([^'""]+)\2[^>]*?>";

            string result = Regex.Match(tempStr, pattern).Groups[3].Value;//bbox 28 27 76 52

[解决办法]
string tempStr = File.ReadAllText(@"C:\Users\myx\Desktop\Test.txt", Encoding.GetEncoding("GB2312"));//读取txt
string pattern = @"<span[^>]*?class=(['""]?)ocrx_word\1[^>]*?title=(['""]?)([^'""]+)\2[^>]*?>200</span>";
