直接上方法
public static ArrayList getImgUrl(string html, string regstr, string keyname)
{
ArrayList resultStr = new ArrayList();
Regex r = new Regex(regstr, RegexOptions.IgnoreCase);
MatchCollection mc = r.Matches(html);
foreach (Match m in mc)
{
resultStr.Add(m.Groups[keyname].Value.ToLower());
}
if (resultStr.Count > 0)
{
return resultStr;
}
else
{
//没有地址的时候返回空字符
resultStr.Add("");
return resultStr;
}
}
调用
var imgs=getImgUrl(pro.Description, @"<IMG[^>]+src=\s*(?:'(?<src>[^']+)'|""(?<src>[^""]+)""|(?<src>[^>\s]+))\s*[^>]*>", "src");
