"\xa2", //chr(162), "\xa3", //chr(163), "\xa9", //chr(169), "",

"\r\n", "" }string s = HTMLfor (int i = 0i <

Regexs.Lengthi++) { s = new Regex(Regexs[i],

RegexOptions.Multiline | RegexOptions.IgnoreCase).Replace(s,

Replaces[i])} s.Replace("<", "")

s.Replace(">", "")s.Replace("\r\n", "")return s

} }

var s="<span>a</span>.... <span>z</span>"

s=s.replace(/<span>(.*?)<\/span>/g,"<input type='text' value='$1' />")

var str = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.1//EN\" \"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd\">"
