急？特殊正则写法！没思路了
string RegexString = "<title>.+?</title>";
string pageStr = "<meta name="description" content="6267 companies listed in 'Agriculture Companies', you can submit free company information here." />";
string resString = "";
Regex reg = new Regex(RegexString, RegexOptions.IgnoreCase);
MatchCollection matches = reg.Matches(pageStr);
foreach (Match match in matches)
{
resString += match.Groups[1].Value;
}
Response.Write(resString+"/Test");



实现功能是：取出description里的之间的值，取<title></title> 比较简单，标签有开始有结尾，这个description没有结尾的正则怎写？



[解决办法]
就一个 description，你所谓的之间的值，是什么，举例说明
[解决办法]
把/>"; 当做结尾不行吗
[解决办法]
(?i)<meta[^>]*name="([^"]+)"[^>]*>

C# code

string RegexString = "(?i)<meta[^>]*name=""([^""]+)""[^>]*>";  string pageStr = @"<meta name=""description"" content=""6267 companies listed in 'Agriculture Companies', you can submit free company information here."" />";  string resString = "";  Regex reg = new Regex(RegexString, RegexOptions.IgnoreCase);  MatchCollection matches = reg.Matches(pageStr);  foreach (Match match in matches)  {  resString += match.Groups[1].Value;  }  Response.Write(resString+"/Test");
