LINQ到XML：如何选择下一个元素 [英] LINQ to XML: How to select the next element

问题描述

我有一个iPhone应用程序plist文件中。它看起来像下面这样：

I have a plist file from an iPhone app. It looks like this below:

<plist version="1.0">
  <dict>
    <key>barcodes</key>
    <array>
      <string>JF893J89FJ-66666</string>
      <string>JF893J89FJ-55555</string>
    </array>
    <key>currentStep</key>
    <integer>1</integer>
    <key>dateFinished</key>
    <date>2010-05-10T18:33:25Z</date>
    <key>dateStarted</key>
    <date>2010-05-10T18:33:25Z</date>
    <key>description</key>
    <string>TEST</string>
    <key>geoRequired</key>
    <string>N</string>
    <key>inProgress</key>
    <string>N</string>
    <key>jobID</key>
    <integer>10085</integer>
    <key>jobSteps</key>
    <array>
      <dict>
        <key>label</key>
        <string>TEST</string>
        <key>response</key>
        <string>matt hudson</string>
        <key>stepID</key>
        <integer>1103</integer>
        <key>typeID</key>
        <integer>4</integer>
      </dict>
    </array>
  </dict>
</plist>

我需要得到jobSteps后的数组。

I need to get the array after jobSteps.

我有这个至今：

XDocument xml = XDocument.Load(rri.Response);

var q = from elements in xml.Descendants("plist").Descendants("dict")
        where elements.Value == "jobSteps"
        select elements;

但是我需要有jobSteps其中的元素之后，以获得下一个项目。

But I need to get the next item after the element that has jobSteps in it.

推荐答案

这并不完全清楚，我亚当的解决方案是否是你想要的，但如果没有，你可能想要看的NextNode 属性：

It's not entirely clear to me whether Adam's solution is what you want, but if not, you might want to look at the NextNode property:

获取此节点的下一个同级节点

Gets the next sibling node of this node.

例如，这个输出数组元素：

For instance, this prints the array element:

using System;
using System.Linq;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XDocument doc = XDocument.Load("test.xml");
        foreach (var element in doc.Descendants("key")
                                   .Where(x => (string) x == "jobSteps"))
        {
            Console.WriteLine(element.NextNode);
        }
    }
}

请注意，它的跳过空白元素之间 - 但如果有是的是与阵列之间的所有文本，这是行不通的 - 所以你想要的：

Note that it's skipping the whitespace between elements - but if there were any text between that and the array, it wouldn't work - so you'd want:

Console.WriteLine(element.NodesAfterSelf().OfType<XElement>().First());
