word转html 清除冗余
<span lang=EN-US style='mso-bidi-font-size:
10.5pt;line-height:150%;color:#009900;background:#F0F1EF'>selector</span>
如何只保留color与background的值。。

[烟灰洒落键盘]

Regex.Replace(str,"([\s\S]*(color:[^>]*)(?=>)[]\s\S*)","${2}")

Regex.Replace(str,"([\s\S]*(color:[^>]*)(?=>)[\s\S]*)","${2}")

Regex reg = new Regex(@"(?is)color:#[0-9a-z]+;background:#[0-9a-z]+");

str=Regex.Replace(str,@"(?i)(<span)[^>]*?(color:#[a-z\d]+;backgroud:#[a-z\d]+'>[^<>]*?</span>)","$1$2");

string str = @"<span lang=EN-US style='mso-bidi-font-size:
 10.5pt;line-height:150%;color:#009900;background:#F0F1EF'>selector</span>";
            str = Regex.Replace(str, @"(?<=style=['""])[\s\S]*?(?=background|color)", "");

结果是这样？ <span style='color:#009900;background:#F0F1EF'>selector</span>

[q107770540]

yourhtml=Regex.Replace(yourhtml,@"(?is)(?<=<span[^>]*?style=(['""])).*?(?=color:#[a-z\d]+;background:#[a-z\d]+\1>[^<>]*?</span>)","");

[骑着蜗牛去爬山]

            string str = @"<span lang=EN-US style='mso-bidi-font-size: 10.5pt;color:#009900;line-height:150%;background:#F0F1EF'>selector</span>";
            str = Regex.Replace(str, @"(?<=style=['""])[^'""]*(?=['""])", delegate(Match m)
            {
                return string.Join(";", m.Value.Split(';').Where(t => Regex.IsMatch(t.Trim(), @"^(background|color):")).ToArray());
            });

再改一下
