替换邮件链接 [英] Replace mailto-links

问题描述

我有以下示例字符串:

var content = "Lorem ipsum dolor sit amet <a href=\"mailto:[e-mail]\">[e-mail]</a> ipsum dolor <a href=\"mailto:[e-mail]\">[e-mail]</a> adipiscing elit.";

当字符串包含mailto-link时，我想替换(操纵)所有的a-tag.

I want to replace (manipulate) all occurrences of the of the a-tag when the string contains a mailto-link.

操纵后的锚应该看起来像这样:

The anchor's should look like after manipulation:

<a href="#" title="protected">[e-mail]</a>

内容字符串可以包含任意数量的邮件链接.

The content string could contain any number of mailto-links.

如何最好地执行此任务?

How can I best perform this task?

推荐答案

如果您有XHTML，请使用Chuck显示的XElement.

If you have XHTML then use XElement as Chuck showed.

如果没有，那么使用正则表达式是可行的方法.像这样:

If not, then regular expressions are the way to go. Something like:

Regex find = new Regex("<a\\b[^>]*href=['\"]mailto:(.*?)['\"]", RegexOptions.Singleline | RegexOptions.IgnoreCase);

警告，我没有测试上面的代码，但我99％确信它是正确的.另外，我可能错过了电子邮件地址中的大写字母，例如>.

Warning, I did not test the above code but I'm 99% certain it is correct. Also, I may have missed a corner case such as a > in the email address.
