将XML读取到字典 [英] Reading XML to a Dictionary

问题描述

我需要阅读一个XML文件，我读了几本指南，只有我不明白的奇怪的单词（比如节点，XML验证等）才感到困惑。
所以，请问我可以通过吗？

I need to read a XML file, I read few guides and I only got confused from weird words that I don't understand (such as nodes, XML validation etc.). So, could you please walk me through?

我有一个以这种格式写的XML文件：

I have a XML file which is written in this format:

<database>
    <def number="1" name="one"/>
    <def number="2" name="two"/>
</database>

我想将其存储在字典中，请告诉我如何做到这一点。
谢谢。

I want to store it in a dictionary, please show me how can I do it. Thanks.

哦，对不起，如果这个问题太基础和不合适。

Oh, and I'm sorry if this question is too basic and inappropriate.

推荐答案

var data = XElement.Parse(xml)
    .Elements("def")
    .ToDictionary(
        el => (int)el.Attribute("number"),
        el => (string)el.Attribute("name")
    );

This：

• 将xml解析成一个 XElement （从< database> 开始）


• 迭代< def ...> 元素


• 使用 @number 作为密钥（解释为 int ），而 @name as值（作为字符串）


• 将此字典分配给数据，它隐式键入为 Dictionary< int，string>

• parses the xml into an XElement (starting at <database>)
• iterates over the <def ...> elements
• forms a dictionary, using @number as the key (interpreting as an int), and @name as the value (as a string)
• assigns this dictionary to data, which is implicitly typed as Dictionary<int,string>
