只得到src值 [英] only get the src value

问题描述

我在数据库中有一个字段，将始终有一个标签。而且大量文字。

I have in the database a field that will always have an tag. and also lots of text..

例如：

Hey there.. whats up?
<img src="http://cdn.theatlantic.com/static/infocus/ngpc112812/s_n01_nursingm.jpg" alt="" />
.. and this is my photo!..

我需要之间仅有什么在

I need to get ONLY what between the

SRC

我想：

public string LinkPicCorrect(string path)
{
    //string input = "[img]http://imagesource.com[/img]";
    string pattern = @"\<img>([^\]]+)\\/>";
    string result = Regex.Replace(path, pattern, m =>
    {
        var url = m.Groups[1].Value;
        // do something with url here
        // return the replace value
        return @"<img src=""" + url + @""" border=""0"" />";
    },
        RegexOptions.IgnoreCase);

    result = "<img src='" + result + "'/>";

    return result;
}

不过，我已经得到了解析错误：

But I've got a parsing error :

异常详细信息：System.ArgumentException：解析\（[^] +）\ /> - 引用未定义的组名IMG

Exception Details: System.ArgumentException: parsing "\([^]]+)\/>" - Reference to undefined group name img.

不知道不过，如果我的代码是在正确的道路......

dont know though if my code is the right path...

推荐答案

此问题已经在这里问。

This question has already been asked here.

string matchString = Regex.Match(original_text, "<img.+?src=[\"'](.+?)[\"'].+?>", RegexOptions.IgnoreCase).Groups[1].Value;
