如何使用XPath获取元素？

My XML is like:

我的XML就像:

<root>
  <section name="blah">
    <item name="asdf">2222</item>
  </section>
</root>

I will have multiple 'sections' in the XML, I want to fetch a particular section.

我将在XML中有多个“部分”,我想获取特定部分。

In this case, I need to get items that are in the section named "blah".

在这种情况下,我需要获取名为“blah”的部分中的项目。

The xpath is then:

然后是xpath:

/root/section[@name='blah']/item

for example, in XmlDocument:

例如,在XmlDocument中:

foreach(XmlElement item in doc.SelectNodes("/root/section[@name='blah']/item"))
{
     Console.WriteLine(item.GetAttribute("name"));
     Console.WriteLine(item.InnerText);
}

Edit re comments: if you just want the sections, then use:

编辑重新评论:如果您只想要这些部分,那么使用:

/root/section[@name='blah']

but then you'll need to iterate the data manually (since you can theoretically have multiple sections named "blah", each of which can have multiple items).

但是你需要手动迭代数据(因为你理论上可以有多个名为“blah”的部分,每个部分可以有多个项目)。
