如何解码CDATA的内容 [英] How to decode the contents of CDATA

问题描述

此方法为我提供了xml文件中CDATA部分的内容。但我想解码这个CDATA.CDATA的内容是0和1的组合。但是编码所以我得到ABC12KJ等不同字母的组合......

如何获得解码数据。 ？

谢谢..

这里是样本文件

This method is giving me the contents of CDATA section in an xml file. But I want to decode this CDATA.Content of CDATA is the combination of 0s and 1s. But the are encoded so I am getting combination of different alphabets like ABC12KJ etc...
How can I get the decoded data. ?
Thanks..
here is the sample file

我的尝试：

What I have tried:

public void GetCDATA()
        {
            var xdoc = XDocument.Load(xmlfilepath);
            var queryCDATAXML = xdoc.DescendantNodes().OfType<XCData>();

            foreach (var item in queryCDATAXML)
            {
                Console.WriteLine(item);
                Console.WriteLine();
            }

        }

推荐答案

看起来数据是Base64 - 维基百科 [ ^ ]编码，这对于XML文档中的二进制数据是常见的。



然后你必须将 CDATA 字符串传递给base64解码器。请参阅 Convert.FromBase64String方法（字符串）（系统） [ ^ ]。



未经测试的例子（我不确定 item 是字符串）：

Looks like the data are Base64 - Wikipedia[^] encoded which is common for binary data in XML documents.

Then you have to pass the CDATA strings to a base64 decoder. See the Convert.FromBase64String Method (String) (System)[^].

Untested example (I don't know for sure if item is a String):

foreach (var item in queryCDATAXML)
{
    byte[] cdata = Convert.FromBase64String(item);
    // Binary data so we have to convert them for display
    Console.WriteLine("   {0}\n", BitConverter.ToString(cdata));
    Console.WriteLine();
}
