C＃正则表达式替换URL [英] C# Regex replace url

问题描述

我有一大堆的这必须由JavaScript调用来代替一个文档中的链接。所有的链接看起来是一样的：

I have a bunch of links in a document which has to be replaced by a javascript call. All the links looks the same:

<a href="http://domain/ViewDocument.aspx?id=3D1&doc=form" target="_blank">Document naam 1</a>
<a href="http://domain/ViewDocument.aspx?id=3D2&doc=form" target="_blank">Document naam 2</a>
<a href="http://domain/ViewDocument.aspx?id=3D3&doc=form" target="_blank">Document naam 3</a>

现在我想所有这些链接被替换为：

Now I want all this links to be replaced to:

<a href="javascript:loadDocument('1','form')">Document naam 1</a>
<a href="javascript:loadDocument('2','form')">Document naam 2</a>
<a href="javascript:loadDocument('3','form')">Document naam 3</a>

所以说ID = 3D在URL中的函数的第一个参数和文档参数是在函数调用的第二个参数。

So the Id=3D in the url is the first parameter in the function and the doc parameter is the second parameter in the function call.

我想这样做，使用正则表达式，因为我觉得这是最快捷的方式。但问题是我的正则表达式的知识太有限

I want to do this using Regex because I think this is the quickest way. But the problem is my regex knowledge is too limited

推荐答案

的 Polygenelubricants 指出我的非常正确的方式，但删除的他的回答：（

Polygenelubricants has pointed me in the very right way, but has removed his answer :(

他给我这。链接多亏了他，我发现我的解决方案：

He gave me this link. Thanks to him I found my solution:

string replaced = "";

string regex = "<a href=3D\"http://\\S+id=3D(\\d+)&doc=3D(\\w+)\" target=3D\"_parent\">";
Regex regEx = new Regex(regex);

replaced = regEx.Replace(mhtFile, "<a href=3D\"javascript:window.parent.loadDocument('$1','$2')\">");

Response.Write(replaced);

对于那些谁感兴趣的话，这个链接是一个.mht文件中。这就是为什么3D是等号（=）之后。变量mhtFile包含纯文本MHT整个MHT文件。

For those who are interested, this links are inside a .mht file. That's why the 3D are placed after the = sign. The variable mhtFile contains the whole mht file in plain mht text.
