读取XMLDocument节点，而不用C＃读取其子节点

Question

Sample XML

<A>
   <B>
      <B1/>

      <B2/>
      <B3/>
      <B4/>
      <B5/>
   </B>
   <C>
      <C1/>
      <C2/>
      <C3/>
      <C4/>
      <C5/>
   </C>
</A>

Query: C# When I read the the child nodes of A it retuns nodes B & C with their child nodes.

Is there any possibility so that I can get only B & C without their respective child nodes

I need to populate the tree with this type of xml & the xml file is quite big. so I need to load the childs at the time of expanding any node

Requirement is Suppose I try to expand A node the I want only B & C,

If I expand B then I want B1 to B5

Answer 1

Use a XmlReader. XmlDocument by design has to load the whole Xml document into memory.

Answer 2

如果使用Java，则可以实现SAX处理程序，以构建DOM并忽略子级。

Answer 3

It's a badly worded question so I'm not entirely sure what you are trying to do but if you just want all the child nodes of the root (A) then use an XmlDocument with XPath like this:

XmlDocument doc = new XmlDocument();
doc.Load(xmlFile);
XmlNodeList nodes = doc.SelectNodes("/A/*");
foreach(XmlNode node in nodes){
   //DO STUFF
}

Answer 4

if i understand the question right, u need to get children of the node without getting their children. this can be done by xquery (child::*)

so if u apply it in A node it will give B and C. if u apply it in B then it will give B1-B5.
