如何从XDocument获取文本值？

I'm having an XDocument.For example,

我有一个XDocument。例如，

<cars>
<name>
<ford>model1</ford>
   textvalue   
<renault>model2</renault>
</name>
</cars>

How to get the text value from the XDocument? How to identify the textvalue among the elements?

如何从XDocument获取文本值？如何识别元素中的textvalue？

Text values are interpreted by XLinq as XText. therefore you can easily check if a node is of type XText or by checking the NodeType see:

XLinq将文本值解释为XText。因此，您可以轻松检查节点是否为XText类型，或者通过检查NodeType，请参阅：

// get all text nodes
var textNodes = document.DescendantNodes()
                        .Where(x => x.NodeType == XmlNodeType.Text);

However, it strikes me that you only want to find that piece of text that seems a bit lonely named textvalue. There is no real way to recognize this valid but unusual thing. You can either check if the parent is named 'name' or if the textNode itself is alone or not see:

然而，令我感到震惊的是，你只想找到一段似乎有点孤独的文本值。没有真正的方法来识别这种有效但不寻常的东西。您可以检查父项是否命名为“name”，或者textNode本身是否单独或不显示：

// get 'lost' textnodes
var lastTextNodes = document.DescendantNodes()
                            .Where(x => x.NodeType == XmlNodeType.Text)
                            .Where(x => x.Parent.Nodes().Count() > 1);

edit just one extra comment, i see that many people claim that this XML is invalid. I have to disagree with that. Although its not pretty, it's still valid according to my knowledge (and validators)

编辑一个额外的评论，我看到很多人声称这个XML是无效的。我不同意这一点。虽然它不漂亮，但根据我的知识（和验证器）它仍然有效

You can use the Nodes property to iterate over the child nodes of the document's root element. From there on, text nodes will be represented by XText instances, and their text value is available through their Value property:

您可以使用Nodes属性迭代文档根元素的子节点。从那时起，文本节点将由XText实例表示，其文本值可通过其Value属性获得：

string textValue = yourDoc.Root.Nodes.OfType<XText>().First().Value;

#3

Assuming the variable "doc" contains the XDocument representing your XML above,

假设变量“doc”包含表示上述XML的XDocument，

doc.XPathSelectElement("cars/name").Nodes().OfType<XText>()

This should give you all of the XText type text nodes that contain plain text that you are looking for.

这应该为您提供包含您正在查找的纯文本的所有XText类型文本节点。
