asp.net开发中,有时需要对读出的文本进行处理,例如不需要html格式,需要数据直接以文本方式显示,这时就需要一个方法来去除html。
具体代码如下:
因为是利用正则来处理,所以需要添加命名空间:
using System.Text.RegularExpressions;
public static string RemoveHTML(string Htmlstring)
{
//删除脚本
Htmlstring = Regex.Replace(Htmlstring, @”<script[^>]*?>.*?</script>”, “”, RegexOptions.IgnoreCase);
//删除HTML
Htmlstring = Regex.Replace(Htmlstring, @”<(.[^>]*)>”, “”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”([\r\n])[\s]+”, “”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”–>”, “”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”<!–.*”, “”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(quot|#34);”, “\””, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(amp|#38);”, “&”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(lt|#60);”, “<“, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(gt|#62);”, “>”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(nbsp|#160);”, ” “, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(iexcl|#161);”, “\xa1”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(cent|#162);”, “\xa2”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(pound|#163);”, “\xa3”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&(copy|#169);”, “\xa9”, RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @”&#(\d+);”, “”, RegexOptions.IgnoreCase);
Htmlstring.Replace(“<“, “”);
Htmlstring.Replace(“>”, “”);
Htmlstring.Replace(“\r\n”, “”);
Htmlstring = HttpContext.Current.Server.HtmlEncode(Htmlstring).Trim();
return Htmlstring;
}
OK!大功告成!
