如何从下向上解析XML文档中的C＃？

How do you parse XML document from bottom up in C#?

例如：

<Employee>
   <Name> Test </name>
   <ID> 123 </ID>
<Employee>
<Company>
    <Name>ABC</company>
    <Email>test@ABC.com</Email>
 </company>

像这些有很多nodes..I需要开始从下向上解析解析like..first ＆LT;的公司和GT; ，然后等on..How DOI去这在C＃？

Like these there are many nodes..I need to start parsing from bottom up like..first parse <company> and then and so on..How doi go about this in C# ?

答

试试这个：

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

或者相反，如果你在一个字符串的XML使用的loadXML 方法。

Or alternatively if you have the XML in a string use the LoadXml method.

一旦你拥有了它加载，你可以使用的SelectNodes 和的SelectSingleNode 查询特定的值，例如：

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "test@ABC.com"

最后，注意，XML是无效的，因为它不包含一个根节点。它必须是这样的：

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>test@ABC.com</Email>
    </Company>
</Data>
