I have an xml document where i need to iterate over all nodes that are direct descendants of the parent.
我有一个xml文档,我需要迭代所有父节点的直接后代节点。
For example i have the following xml document
例如,我有以下xml文档
<root>
<node1>val1</node1>
<node2>val2</node2>
<nodes>
<nestedNode>nestedvalue</nestedNode>
</nodes>
</root>
I have the following code which gets me all the elements:
我有以下代码,它为我提供了所有元素:
XmlNodeList nodes = doc.SelectNodes("//*");
This returns node1, node2, and nestedNode. What i want is only node1 and node2 and to ignore any nested values.
这将返回node1,node2和nestedNode。我想要的只是node1和node2,并忽略任何嵌套值。
Thanks in advance for any help.
在此先感谢您的帮助。

To select elements that are children of the root element you would use the xpath:
要选择作为根元素的子元素的元素,您将使用xpath:
/root/*
or in general:
或者一般来说:
/*/*
You should not traverse the all descendants here (//...
) as that will go through all elements in the document. You would have to add additional filtering which would make the query unnecessarily complicated:
你不应该遍历这里的所有后代(// ...),因为它将遍历文档中的所有元素。您将不得不添加额外的过滤,这将使查询不必要地复杂化:
//*[parent::*[not(parent::*)]]
However, you want to filter out elements that do not have other child elements so you need to add the condition not(*)
:
但是,您希望过滤掉没有其他子元素的元素,因此您需要添加条件not(*):
/*/*[not(*)]
