在麻烦你帮我加个从页面上面获取<span class="prodList_gridViewCell"></span> 标签内的这些参数，页面有多个这样的span

Answer 1

这里分了两部分来取,你试试看结果.            string str = File.ReadAllText(@"E:\1.txt");
            Regex span = new Regex(@"(?is)(?<=<span[^>]*?class=""prodList_gridViewCell""[^>]*?>).*(?=</span>)");
            Regex reg = new Regex(@"(?is)<img[^>]*?src=""([^""]+)""[^>]*?>|(?<=<(?!font\b)[^>]*?>)(?!(?:\s*|(?:&nbsp;)*)<)([^<>]+?)(?=</?[^>]+?>)");
            foreach (Match mSpan in span.Matches(str))
            {
                foreach (Match m in reg.Matches(mSpan.Value))
                {
                    if (m.Groups[1].Success)
                        Console.WriteLine(m.Groups[1].Value);
                    else
                        Console.WriteLine(m.Groups[2].Value);
                }
            }

Answer 2

第一部分取出来的不对，不是<span class="prodList_gridViewCell">的标签也出来了 

Answer 3

http://www.skinstore.com/borghese.aspx?avs=Brand%7cBorghese&fa=25我只能给你连接喽，内容太多

Answer 4

看了下,太麻烦了,还有嵌套的.
用了平衡组取嵌套的,然后在获取你要的数据,你看下结果是不是你要的            string str = File.ReadAllText(@"E:\1.txt");
            Regex span = new Regex(@"(?is)<span\s*class=""prodList_gridViewCell"">(?:(?!</?span).)*(?:(?:(?<Open><span[^>]*?>)(?:(?!</?span).)*)*(?:(?<-Open></span>)(?:(?!</?span).)*)*)*(?!(Open))</span>");
            Regex reg = new Regex(@"(?is)<img[^>]*?src=""([^""]+)""[^>]*?>|(?<=<(?!font\b)[^>]*?>)(?!(?:\s*|(?:&nbsp;)*)<)([^<>]+?)(?=</?[^>]+?>)");
            foreach (Match mSpan in span.Matches(str))
            {
                foreach (Match m in reg.Matches(mSpan.Value))
                {
                    if (m.Groups[1].Success)
                        Console.WriteLine(m.Groups[1].Value);
                    else
                        Console.WriteLine(m.Groups[2].Value);
                }
            }
