如何使用元素将字符串解析为XML？

Question

I have string s and it looks:

<root><p>hello world</p>&nbsp;my name is!</root>

I have next code:

try
{
    m_Content = XDocument.Load(new StringReader(s));
}
catch (XmlException ex)
{
    ex.Data["myerror"] = s;

    throw;
}

As you see, I want to load string with all elements like   and make it view. But I've got XmlException:

Reference to undeclared substitution to "nbsp"

Any ideas how to do it right?

ChrisShao offered a good idea: put my string in <![CDATA[ tag, but unfortunately it doesnt solve my problem. I have a big string with lots of tags and few big texts in which I can meet   elements. If use System.Web.HttpUtility.HtmlDecode I lose all these elements and get " " fields.

Answer 1

Responding to your Added section. The blank ( " " ) fields you get is correct representation of   when it is rendered. Correct encoding of   for use in xml is   [ Reference ].

If you really want to see   instead of " " when the string loaded to XDocument , try to encode ampersand char ( & ) with & . Replace   with   [ Reference ].

Answer 2

使用System.Web.HttpUtility.HtmlDecode或System.Net.WebUtility.HtmlDecode

我认为您应该将字符串放入CDATA块中，如下所示：

<root><![CDATA[<p>hello world</p>&nbsp;my name is!]]></root>
