c# - 如何使用正则表达式 html 将行空白删除为纯文本？

Question

我使用正则表达式将 html 转换为纯文本。

你能帮我用正则表达式删除行空白吗

我的 html:

<div class="short-description">
<div class="short-description">
<div class="short-description">
<div class="short-description">
<div class="short-description">
<div class="short-description">
<div class="short-description">
<div class="short-description">
<div class="short-description">
<ul style="margin: 0px; padding: 0px; font-family: Tahoma, Verdana; color: #000000; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 1; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff;">

</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
                            </div>

还有我的正则表达式:

Regex.Replace(Model.MetaDescription, @"<(.|\n)*?>","")

这个结果(图片): Result regex.replace

下图怎么样 Result regex.replace

正如它提到的here ，您可以使用免费开源 HtmlAgilityPack .检查sample

a method that converts from HTML to plain text.

var plainText = ConvertToPlainText(string html);

Feed it an HTML string like

<b>hello world!</b><br /><i>it is me! !</i>

你会得到一个纯文本结果，如:

hello world!
it is me!
