C# 如何截取一段内容，不要样式表，标点符号也要获取的内容如下：span styleborder:1px solid red江，苏

C# 如何截取一段内容，不要样式表，标点符号也要获取的
内容如下：
<span style="border:1px solid red">江，苏<font color="red" size="5">省、南</font>京市</span>
获取后得到的是：江,苏省、南京市

这样的

C# code

        string sourcestr = "<span style="border:1px solid red">江，苏<font color="red" size="5">省、南</font>京市</span>"        Regex regx = new Regex(@"[\u4e00-\u9fa5]+");        List<string> urllist = new List<string>();        string emp = "";        MatchCollection mcurl = regx.Matches(sourcestr);        foreach (Match sk in mcurl)        {            emp += sk.Groups[0].Value        }

这段代码只能获取到江苏省南京市

求解：

[解决办法]

C# code

public static string ClearMarket(string oldstring) {            string str  = Regex.Replace(oldstring, @"<(.[^>]*)>", "", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"([\r\n])[\s]+", "", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"-->", "", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"<!--.*", "", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(quot|#34);", "\"", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(amp|#38);", "&", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(lt|#60);", "<", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(gt|#62);", ">", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(nbsp|#160);", " ", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(iexcl|#161);", "\xa1", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(cent|#162);", "\xa2", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(pound|#163);", "\xa3", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&(copy|#169);", "\xa9", RegexOptions.IgnoreCase);            str = Regex.Replace(str, @"&#(\d+);", "", RegexOptions.IgnoreCase);            str.Replace("<", "");            str.Replace(">", "");            str.Replace("\r\n", "");            str = HttpContext.Current.Server.HtmlEncode(str).Trim();            return str;        }
[解决办法]
str=Regex.Replace(str,"<[^<>]+?>","");
[解决办法]
一段vb的
Function   replHTML(strng)  
Dim   reg  
Set   reg   =   new   RegExp  
reg.Pattern   =   " <[^> ]+> "  
reg.Global   =   True  
replHTML   =   reg.Replace(strng,   " ")  
Set   reg   =   Nothing  
End   Function

改改就可以用，思想是去掉所有的<[^> ]+>,也就是html标签
