Hi Everyone,

How can I check for end elements in a XmlNodeList that consists of all
the children nodes in my XML document?
Can I avoid using XmlReader or XPath Navigator? Thanks for any help!

I'm using Visual Studio 2005 and my application is in C#.

How did this XmlNodeList came to be? Generally it cannot include End-
Element nodes, they are an artificial node type for use with sequential
processors, the document object model does not store them, they are
implied by the parent/child relationships stored in it.

Hi Bjoern!

Thanks for your reply (on two forums!), I was afraid that might be the
case. My XmlNodeList is created in a recursive loop that saves all the
child nodes at any given node in the XmlDocument. Take a look:

// This function writes the name of every element it encounters to a
textbox on the C# form

private void findElements( XmlNode parent )
{

if (parent.Name.Equals("book")) //All element names with book in my
xml document
{

userLog.Text += ("The name of your book is" +
parent.Attributes[0].Value ); //write to textbox

}

if (parentNode.HasChildNodes) //Only do recursion if there are child
nodes left
{
XmlNodeList nodelist = parent.ChildNodes; //store all
child nodes in a list

foreach (XmlNode node in nodelist) //for each child in
the list
{

drawTree(node); //recursively iterate through the
element names

}
}
}

The problem is (as you already know) that when I read in the names, I
only know where the nodes start, but if I wanted to print out the
names of the closing tags (end elements), I can see no way to access
them.

I guess my best bet is to either change my structure to use XmlReader
or use XPath navigator to access the end elements. All I want to do is
print them the screen. Is there an equivalent to XmlNodeList in
XmlReader?

Thanks for your help!!

The names of the end tags are the same as the names of the start tags.

Hi John,

YES! I figured that out this morning as well but thanks for the reply!
It turns out all I had to do was look for the name again after the
recursive loop and close each tag! Why is that the answer with XML is
always way easier than whatever I'm thinking? hehe.

Thanks!
