C#.net中的正则表达式 [英] Reqular expressions in c# .net

问题描述

大家好，

你能告诉我正则表达式来分割图像src

例如字符串如下

Hi All,

Can u tell me regular expression to split image src

For example string is like below

string testing="<img src=\"cid:tmpImage.gif\">,cdefetfdgfdg ,ewrewrewr,<img src=\"cid:tmpImage1.gif\">,<img src=\"cid:tmpImage2.gif\">,<img src=\"cid:tmpImage3.gif\">,<img src=\"cid:tmpImage4.gif\">";
    string[] splitText = Regex.Split(testing, @"(<img([^>]+)>)");

分割后，我需要以下形式


src =''images/img1.jpg''
src =''images/img2.jpg''
src =''images/img3.jpg''
src =''images/img4.jpg''


感谢

after split I need in the following form


src=''images/img1.jpg''
src=''images/img2.jpg''
src=''images/img3.jpg''
src=''images/img4.jpg''


Thanks

推荐答案

使用Regex可以找到许多内容，但是在这种情况下，某些HTML解析器可能会做得更好.如果此HTML是格式正确的XML，则非常容易，因为XML解析器(至少其中三个)在.NET中很容易获得.如果HTML格式不正确，那就更糟了，但是您可以使用一些可用的HTML解析器来处理.试试这个:

Many things can be found with Regex, but in this case some HTML parser could do better. It''s very easy if this HTML is well-formed XML, as XML parsers (at least three of them) are readily available in .NET. If the HTML is not well-formed, it''s much worse, but you can use some available HTML parser which can deal with that. Try this one:

看看下面的代码是否有帮助

Hi,
See if following piece of code helps

string testing = "<img src="\"cid:tmpImage.gif\"">,cdefetfdgfdg ,ewrewrewr,<img src="\"cid:tmpImage1.gif\"">,<img src="\"cid:tmpImage2.gif\"">,<img src="\"cid:tmpImage3.gif\"">,<img src="\"cid:tmpImage4.gif\"">";
Regex regex = new Regex(@"(src([^>]+))");
MatchCollection cl = regex.Matches(testing);

foreach (Match match in cl)
{
    Console.WriteLine(match.Value);
}

它给我的输出为

Its giving me output as

src="cid:tmpImage.gif"
src="cid:tmpImage1.gif"
src="cid:tmpImage2.gif"
src="cid:tmpImage3.gif"
src="cid:tmpImage4.gif"

希望能达到目的.如果有帮助，请将答案标记为解决方案和/或赞成.
