public static string[] GetHtmlImageUrlList(string sHtmlText)
{ // 定義正則表達(dá)式用來(lái)匹配 img 標(biāo)簽
Regex regImg = new Regex(@"<input\b[^<>]*?\bsrc=[\s\t\r\n]*[""']?[\s\t\r\n]*(?<inputValue>[^\s\t\r\n""'<>]*)[^<>]*?/?[\s\t\r\n]*>", RegexOptions.IgnoreCase); // 搜索匹配的字符串
MatchCollection matches = regImg.Matches(sHtmlText); int i = 0; string[] sUrlList = new string[matches.Count]; // 取得匹配項(xiàng)列表
foreach (Match match in matches)
sUrlList[i++] = match.Groups["inputValue"].Value; return sUrlList;
}(?<inputValue>[^\s\t\r\n""'<>]*)和match.Groups["inputValue"].Value;來(lái)怎么理解,能否在舉個(gè)就簡(jiǎn)單例子
