如何使用RegEx Asp.net C＃抓取BODY html标签内的所有内容（来自字符串）

Question

{Yup, the above more or less explains it} :)

Regex oRegex = new Regex("<body.*?>(.*?)</body>", RegexOptions.Multiline);

The above doesnt seem to work if the body has any attributes in it.

Answer 1

With the HTML Agility Pack (assuming it is html, not xhtml):

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);
string body = doc.DocumentNode.SelectSingleNode("/html/body").InnerHtml;

Answer 2

Don't use a regular expression. Use something that's meant to parse XML/HTML:

XmlDocument.SelectSingleNode("//body").InnerXml;

Load your string into an XmlDocument , use the SelectSingleNode function (which takes an XPath expression as a parameter), then extract what you need from the resulting XmlNode .

Answer 3

我最终通过使用RegexOptions.Singleline而不是使用RegexOptions.Multiline解决了它
