我有一个包含一个HTML页面的响应一个字符串变量。它包含数百个标签，其中包括以下三个HTML标签：

I have a string variable that contains an HTML page's response. It contains hundreds of tags, including the the following three html tags:

<tag1 prefix1314030136543="2">
<tag2 prefix131403013654="1" anotherAttribute="432">
<tag3 prefix13140301376543="4">

我需要能够带出一个以preFIX开始伴随着它的价值，无论标记名的任何属性。最后，我想有：

I need to be able to strip out any attribute that starts with "prefix" along with its value, regardless of tag name. In the end, I'd like to have:

<tag1>
<tag2 anotherAttribute="432">
<tag3>

我使用C＃。我假设正则表达式的解决方案，但我是可怕的与正则表达式，并希望有人能帮助我在这里。

I am using C#. I'm assuming RegEx is the solution, but I'm horrible with RegEx and hope someone can help me out here.

推荐答案

看的Html敏捷包。

使用正则表达式：

(?<=<[^<>]*)\sprefix\w+="[^"]"\s?(?=[^<>]*>)

var result = Regex.Replace(s, 
    @"(?<=<[^<>]*)\sprefix\w+=""[^""]""(?=[^<>]*>)", string.Empty);
