我需要将 HTML 内容插入到一个 XML 文档中，这可能吗? 或者 HTML 内容应该用 BASE64编码，还是使用类似的其他编码方式？

You can include HTML content. One possibility is encoding it in BASE64 as you have mentioned.

Another might be using CDATA tags.

Example using CDATA:

<xml>
<title>Your HTML title</title>
<htmlData><![CDATA[<html>
<head>
<script/>
</head>
<body>
Your HTML's body
</body>
</html>
]]>
</htmlData>
</xml>

Please note:

CDATA's opening character sequence: <![CDATA[

CDATA's closing character sequence: ]]>

The purpose of BASE64 encoding is to take binary data and be able to persist that to a string. That benefit comes at a cost, an increase in the size of the result (I think it's a 4 to 3 ratio). There are two solutions. If you know the data will be well formed XML, include it directly. The other, an better option, is to include the HTML in a CDATA section within an element within the XML.

so long as your html content doesn't need to contain a CDATA element, you can contain the HTML in a CDATA element, otherwise you'll have to escape the XML entities.

<element><![CDATA[<p>your html here</p>]]></element>

<element>&lt;p&gt;your html here&lt;/p&gt;</element>

Please see this.

Text inside a CDATA section will be ignored by the parser.

This is will help you to understand the basics about XML

Just put the html tags with there content and add the xmlns attribute with quotes after the equals and in between the quotes is http://www.w3.org/1999/xhtml
