blocks|key|211946|text|HTML的基本形式就是XML。您可以解析XmlDocument对象中的文本，然后在根元素上调用InnerText来提取文本。这将以任何形式剥离所有HTML标签，还可以处理特殊字符，如一下子处理所有字符。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|211947|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>HTML is in its basic form just XML. You could Parse your text in an XmlDocument object, and on the root element call InnerText to extract the text. This will strip all HTML tages in any form and also deal with special characters like &amp;lt; &amp;nbsp; all in one go.</p>


blocks|key|212009|text|我使用了@RaviThapliyal+&+@Don+Rolling的代码，但做了一些修改。因为我们用空字符串替换了字符串，而应该用空格替换，所以增加了一个额外的步骤。它对我来说就像一个护身符。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|212010|public+static+string+FormatString(string+value)+{
++++var+step1+=+Regex.Replace(value,+@"<[%5E>]%2B>",+"").Trim();

<p>I have used the @RaviThapliyal &amp; @Don Rolling's code but made a little modification. Since we are replacing the &amp;nbsp with empty string but instead &amp;nbsp should be replaced with space, so added an additional step. It worked for me like a charm.</p>

<pre><code>public static string FormatString(string value) {
    var step1 = Regex.Replace(value, @"&lt;[^&gt;]+&gt;", "").Trim();
    var step2 = Regex.Replace(step1, @"&amp;nbsp;", " ");
    var step3 = Regex.Replace(step2, @"\s{2,}", " ");
    return step3;
}

<p>Used &amp;nbps without semicolon because it was getting formatted by the Stack Overflow.</p>
