如何从 XDocument 对象获取子元素列表？

我试图从如下所示的 XML 文件中获取所有“视频”元素及其属性：

<?xml version="1.0" encoding="utf-8" ?>
<videos>
  <video title="video1" path="videos\video1.wma"/>
  <video title="video2" path="videos\video2.wma"/>
  <video title="video3" path="videos\video3.wma"/>
</videos>

以下内容将仅选择根节点和所有子节点。我想将所有“视频”元素放入 IEnumerable 中。有人可以告诉我我做错了什么吗？

 IEnumerable<XElement> elements = from xml in _xdoc.Descendants("videos")
                           select xml;

上面返回一个长度== 1的集合。它包含根元素和所有子元素。

I am trying to get all of the "video" elements and their attributes from an XML file that looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<videos>
  <video title="video1" path="videos\video1.wma"/>
  <video title="video2" path="videos\video2.wma"/>
  <video title="video3" path="videos\video3.wma"/>
</videos>

The following will only select the root node and all of the children. I would like to get all of the 'video' elements into the IEnumerable. Can someone tell me what I'm doing wrong?

 IEnumerable<XElement> elements = from xml in _xdoc.Descendants("videos")
                           select xml;

The above returns a collection with a length == 1. It contains the root element and all the children.

您想要选择后代（“视频”）。 “videos”似乎是您的根条目，其中有 1 个元素。视频的内部元素就是你想要查询的内容。

示例：

var query = from video in document.Descendants("video")
            select new
            {
                Title = video.Attribute("title").Value,
                Path = video.Attribute("path").Value
            };

这为您提供了一个具有两个字符串属性的匿名类型的 IEnumerable。否则，您可以简单地选择“video”并获取 IEnumerable，您可以根据需要进一步解析它。

You want to select Descendants("video"). "videos" appears to be your root entry, of which there is 1 element. The inner elements of videos are what you want to query.

Example:

var query = from video in document.Descendants("video")
            select new
            {
                Title = video.Attribute("title").Value,
                Path = video.Attribute("path").Value
            };

That gives you an IEnumerable of an anonymous type with two string properties. Otherwise, you could simply select "video" and get an IEnumerable<XElement>, which you would further parse as needed.
