XML is so versatile...

<pre><code>&lt;DATA&gt;

XML is like violence - If it doesn't solve your problem, you're not using enough of it.

EDIT:

BTW: Base64 + CDATA is probably the best solution

I had this problem just last week. I had to serialize a PDF file and send it, inside an XML file, to a server.

If you're using .NET, you can convert a binary file directly to a base64 string and stick it inside an XML element.

<pre><code>string base64 = Convert.ToBase64String(File.ReadAllBytes(fileName));
</code></pre>

Or, there is a method built right into the XmlWriter object. In my particular case, I had to include Microsoft's datatype namespace:

<pre><code>StringBuilder sb = new StringBuilder();
System.Xml.XmlWriter xw = XmlWriter.Create(sb);
xw.WriteStartElement("doc");
xw.WriteStartElement("serialized_binary");
xw.WriteAttributeString("types", "dt", "urn:schemas-microsoft-com:datatypes", "bin.base64");
byte[] b = File.ReadAllBytes(fileName);
xw.WriteBase64(b, 0, b.Length);
xw.WriteEndElement();
xw.WriteEndElement();
string abc = sb.ToString();
</code></pre>

The string abc looks something that looks like this:

<pre><code>&lt;?xml version="1.0" encoding="utf-16"?&gt;
&lt;doc&gt;
 &lt;serialized_binary types:dt="bin.base64" xmlns:types="urn:schemas-microsoft-com:datatypes"&gt;
 JVBERi0xLjMKJaqrrK0KNCAwIG9iago8PCAvVHlwZSAvSW5mbw...(plus lots more)
 &lt;/serialized_binary&gt;
&lt;/doc&gt;
</code></pre>

blocks|key|1565701|text|如果您可以控制XML格式，就应该彻底解决这个问题。与其附加二进制XML，不如考虑如何封装包含多个部分的文档，其中一个部分包含XML。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1565702|传统的解决方案是归档(例如tar)。但是，如果你想保持你的封闭文件在一个基于文本的格式，或者如果你不能访问一个文件存档库，也有一个标准化的方案，这是大量使用的电子邮件和超文本传输协议，这是multipart/*+MIME与Content-Transfer-Encoding:+binary。|offset|length|1565703|例如，如果您的服务器通过HTTP通信，而您想要发送一个多部分文档，主要是引用二进制数据的XML文档，则HTTP通信可能如下所示：|1565704|POST+/+HTTP/1.1

If you have control over the XML format, you should turn the problem inside out. Rather than attaching the binary XML you should think about how to enclose a document that has multiple parts, one of which contains XML.
The traditional solution to this is an archive (e.g. tar). But if you want to keep your enclosing document in a text-based format or if you don't have access to an file archiving library, there is also a standardized scheme that is used heavily in email and HTTP which is <a href="https://www.rfc-editor.org/rfc/rfc2387" rel="nofollow noreferrer">multipart/* MIME</a> with <a href="https://www.rfc-editor.org/rfc/rfc3030" rel="nofollow noreferrer">Content-Transfer-Encoding: binary</a>.
For example if your servers communicate through HTTP and you want to send a multipart document, the primary being an XML document which refers to a binary data, the HTTP communication might look something like this:
<pre><code>POST / HTTP/1.1
Content-Type: multipart/related; boundary=&quot;qd43hdi34udh34id344&quot;
... other headers elided ...

--qd43hdi34udh34id344
Content-Type: application/xml

&lt;myxml&gt;
 &lt;data href=&quot;cid:data.bin&quot;/&gt;
&lt;/myxml&gt;
--qd43hdi34udh34id344
Content-Id: &lt;data.bin&gt;
Content-type: application/octet-stream
Content-Transfer-Encoding: binary

... binary data ...
--qd43hdi34udh34id344--
</code></pre>
As in above example, the XML refer to the binary data in the enclosing multipart by using a <code>cid</code> URI scheme which is an identifier to the Content-Id header. The overhead of this scheme would be just the MIME header. A similar scheme can also be used for HTTP response. Of course in HTTP protocol, you also have the option of sending a multipart document into separate request/response.
If you want to avoid wrapping your data in a multipart is to use data URI:
<pre><code>&lt;myxml&gt;
 &lt;data href=&quot;data:application/something;charset=utf-8;base64,dGVzdGRhdGE=&quot;/&gt;
&lt;/myxml&gt;
</code></pre>
But this has the base64 overhead.

I have two applications written in Java that communicate with each other using XML messages over the network. I'm using a SAX parser at the receiving end to get the data back out of the messages. One of the requirements is to embed binary data in an XML message, but SAX doesn't like this. Does anyone know how to do this?

UPDATE: I got this working with the <a href="http://commons.apache.org/codec/apidocs/org/apache/commons/codec/binary/Base64.html" rel="noreferrer">Base64</a> class from the <a href="http://commons.apache.org/codec/" rel="noreferrer">apache commons codec library</a>, in case anyone else is trying something similar.

How do you embed binary data in XML?

我有两个用Java编写的应用程序，它们通过网络使用XML消息相互通信。我在接收端使用SAX解析器从消息中提取数据。其中一个要求是将二进制数据嵌入到XML消息中，但是SAX不喜欢这样。有人知道怎么做吗？更新:我使用中的类实现了这一点，以防其他人也在尝试类似的东西。
