C# XML 节点适用于元素但不适用于元素 [英] C# XML Node Works with Element But Not with Elelments

问题描述

我想在下面的xml数据中获取suras的子节点；

i want to get the child nodes of suras in the following xml data;

<suras alias="chapters">
    <sura index="1" ayas="7" start="0" name="الفاتحة" tname="Al-Faatiha" ename="The Opening" type="Meccan" order="5" rukus="1" />
    <sura index="2" ayas="286" start="7" name="البقرة" tname="Al-Baqara" ename="The Cow" type="Medinan" order="87" rukus="40" />
    <sura index="3" ayas="200" start="293" name="آل عمران" tname="Aal-i-Imraan" ename="The Family of Imraan" type="Medinan" order="89" rukus="20" />
    <sura index="4" ayas="176" start="493" name="النساء" tname="An-Nisaa" ename="The Women" type="Medinan" order="92" rukus="24" />
    <sura index="5" ayas="120" start="669" name="المائدة" tname="Al-Maaida" ename="The Table" type="Medinan" order="112" rukus="16" />
</suras>

suras 节点运行正常，但是当我尝试访问 sura 节点时，我无法将其作为 suras 的 Elements>;
如您所见，如果我调试父节点，即 suras 节点，我可以清楚地正确看到第一个和最后一个节点.但是当我尝试查询它的 Elements 或 Decendents 时，我什么也没得到.检查以下屏幕截图；同样，如果我将代码更改为 Element("sura") 而不是 Elements("sura")，那么它只显示第一个节点检查这个；所以，我的问题是，为什么我没有得到子节点，即 surah?

The suras node is comming fine but when i try to access the sura node, i can't get it as an Elements of suras;
as you can see if i debug the parent i.e suras node, i can clearly see the first and last node correctly. But when i try to query its Elements or Decendents, i dont' get anything. Check the following screen shot; Similarly, if i change my code to Element("sura") instead of Elements("sura"), then it only shows first node check this; So, my question is, Why i am not getting the child nodes i.e surah?

推荐答案

它确实有效，只是你不能那样看.尝试遍历 Elements("suras")，你会得到很好的结果:

It is actually worked, you just can't see it that way. Try to iterate through Elements("suras") and you'll get the result just fine :

....
var test2 = test.Elements("sura");
foreach (XElement sura in test2)
{
    MessageBox.Show(sura.ToString())
    //or print to VS output window :
    //Debug.WriteLine(sura.ToString());
}

或者通过调用 .ToList() 或 .ToArray() 来具体化查询，以便无需循环即可查看实际结果:

Or materialize the query to be able to see the actual result without looping, by calling .ToList() or .ToArray() :

var test2 = test.Elements("sura").ToList();
