Asp.net 正则表达式 取图片路径

[live517]

我写有这样的正则表达式 目的是获得FCkeditor中的图片路径 ，可发现 来Src ="*.*"后面得属性也取出来了，align="absMiddle 不知道有没有更准确的方法~~。
System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(@"<img[^>].*?src=""(?<src>[^""].*)""[^>].*?>",System.Text.RegularExpressions.RegexOptions.IgnoreCase);
System.Text.RegularExpressions.MatchCollection m = reg.Matches(str); //设定要查找的字符串
if (m.Count > 0)
{
return (m[0].Groups["src"].ToString());
}
else
{

reg = new System.Text.RegularExpressions.Regex(@"<input[^>].*?src=""(?<src>[^""].*)""[^>].*?>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
m = reg.Matches(str);
if (m.Count > 0)
{
return (m[0].Groups["src"].ToString());
}
else
{
return "";
}



}

Regex regex = new Regex(@"<img.*src=[\']?([^\']*)[\']?[^/]*[/]?>”, RegexOptions.Compiled | RegexOptions.IgnoreCase );

foreach(Match matchItem in regex.Matche(""))
{
if(matchItem.Groups[1]!= null )
{
str+=matchItem.Groups[1].Value;
}
}

不清楚你的需求，看你的代码猜的

MatchCollection mc = Regex.Matches(yourStr, @"(?<=<(?:input|img)(?:(?!src)[\s\S])*src=(['""]?))[^""'\s>]*(?=\1)", RegexOptions.IgnoreCase);
foreach (Match m in mc)
{
    richTextBox2.Text += m.Value + "\n";
}

还是不对 我之前那个 能截取出图片路径 不过连路径后面的也截出来了如：/Upload/images/Article/images_2(5).jpg" vspace="2 我只想要路径

Regex r = new Regex(@"<img src=""(?<src>[^""]*)""+?[^>]*>");
System.Text.RegularExpressions.MatchCollection m = r.Matches("<img src=\"http://cc.com/aabc.jpg\" vspace=\"2\" />");
Console.WriteLine(m[0].Groups["src"].ToString());
------------------------------------
输出：
http://cc.com/aabc.jpg

protected void Button1_Click(object sender, EventArgs e)
    {
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://www.163.com");
        request.Timeout = 20000;
        request.ServicePoint.ConnectionLimit = 100;
        request.ReadWriteTimeout = 30000;
        request.Method = "GET";
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        if (response.StatusCode != HttpStatusCode.OK)
            return;
        StreamReader sr = new StreamReader(response.GetResponseStream());

        IList<string> ls = GetPicPath(sr.ReadToEnd());
        for (int i = 0; i < ls.Count;i++ )
        {
               Response.Write(ls[i].ToString()+"<br/>");

        }

        Response.End();
    }
    public IList<string> GetPicPath(string M_Content)
    {
        IList<string> im = new List<string>();//定义一个泛型字符类
        Regex reg = new Regex(@"<img.*?src=""(?<href>[^""]*)""[^>]*>", RegexOptions.IgnoreCase);
        MatchCollection mc = reg.Matches(M_Content); //设定要查找的字符串
        foreach (Match m in mc)
        {
            im.Add(m.Groups["href"].Value);
        }
        return im;

    }

你把"<img.*?src=""(?<href>[^""]*)""[^>]*>
换成"<input.*?src=""(?<href>[^""]*)""[^>]*>", 就OK
