推荐答案

如果要从XML中提取文本并进行处理，请参见删除所有HTML标记，并仅在内部显示纯文本(以防XML格式不正确) [ ^ ].

如果要提取XML数据的特定部分，则可以尝试类似

If it''s about extracting some text from XML and process it, see http://support.microsoft.com/kb/317662[^].

If you insist on using Regex to extract all text from the XML, see Remove all the HTML tags and display a plain text only inside (in case XML is not well formed)[^].

If you want to extract a specific portion of the XML data, you may try something like

string xml = ...;
var match = Regex.Match(xml, @"<MyElement.*?>([\s\S]*?)</MyElement>");
string result = match.Success ? match.Group[1].Value : null;

您仍然面临文本可能包含xml实体的问题.这些将需要替换为相应的普通字符.这需要一些创造力.然后我将放弃正则表达式解决方案并使用xml dom方法，例如通过使用 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.loadxml.aspx [ ^ ]并添加相应节点的内部文本.

You still face the problem that the text may contain xml entities. These would need to be replaced by the respective plain characters. This needs a bit of creativity. I would then discard the regex solution and use xml dom approach, e.g. by employing http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.loadxml.aspx[^] and accesing the inner text of a respective node.
