Question

所以我想说我有这个XML文档：

我想务实地获得两个值

1）标题＆gt;安全＆gt; EncryptedKey＆gt; CipherData＆gt;的CipherValue。所以这将是ANCElFZ5v .... ==

2）身体＆gt;加密数据＆gt; CipherData＆gt;的CipherValue。所以它将是3kESnJnhc8K .....

我一直在尝试使用XML到LINQ，但似乎无法弄明白。

我一直在尝试各种各样的事情。但似乎没有用。意思是我没有得到任何价值。

XDocument file = XDocument.Load(stream);
var keyEnc = file.Root.Elements("Header").Elements("Security").Elements("EncryptedKey").Elements("CipherData").Elements("CipherValue").ToList();

Answer 1

命名空间是个问题 var doc = XDocument.Load（stream）; XNamespace ns_e =“http://www.w3.org/2001/04/xmlenc#”;

var encrypKeys = doc.Root.Descendants（ns_e +“CipherValue”）。ToList（）;

从XML Document获取值
