XML Parser with Recursive Function

[John Underwood]

Hi.. I was hoping someone could help me understand whats happening
in my code, it works fine, I just don't understand one part of it
and would like to.. I'll paste the code and xml from my file below..

Ok here's my question:

When I open the xml file, it calls myTest and passes in the xmlNode
and is recursive in calling itself.. I can get all the data just
fine. What I don't understand is when it reaches the line:

if (inXmlNode.HasChildNodes)

and that node has no children so it's false, it of course skips
the code in braces.. If i'm stepping through the code I notice at this point it
goes to the closing brace for the myTest function, then when i step
again, it goes to the following line.

for(int i = 0; i<=nodeList.Count - 1; i++)

At this point the node has stepped back one.. For example: In my xml
code the HasChildNodes would be false when the node was equal to <mytest>,
but after stepping to the bottom brace(after the hasChildNodes was false),
and then stepping again, it jumps
back to the for statement I mentioned above, and the node (inXmlNode)
is now the previous node <new> .. Now it increments i in the for
statement and fails, so it goes to the bottom brace again, then I step
one more time, it goes back to the For statement, and now the node (inXmlNode)
is equal to <xmltest> the previous node.. It now moves on to the next
node which is <view> in this example. So it works fine, but I don't get
how the Node is moving back a step, from the point of the bottom brace, to the
previous step, which puts it back at the for statement again.

It moves from <mytest> to <new> back to <xmltest> in the scenario I just
explained, and i'm not understand how...


I really hope I explained this well, I'm pretty new to this stuff, sorry
for so long, was not sure how to better explain it.. any help would
be great appreciated..

Thanks,
John Underwood

XML I'm reading in............

<?xml version="1.0"?>
<xmltest>
<new value="someValue" label="someLabel">
<mytest value="someValue" label="someLable"/>
</new>
<view value="someValue" label="someLable"/>
</xmltest>

private void button2_Click(object sender, System.EventArgs e)
{
XmlDocument dom = new XmlDocument();
XmlTextReader reader = new XmlTextReader(@"\XMLFile1.xml");
dom.Load(reader);
myTest(dom.DocumentElement);
}
private void myTest(XmlNode inXmlNode)
{
XmlNode xNode;
XmlNodeList nodeList;

if (inXmlNode.HasChildNodes)
{
nodeList = inXmlNode.ChildNodes;

for(int i = 0; i<=nodeList.Count - 1; i++)
{
xNode = inXmlNode.ChildNodes;
myTest(xNode);

}

}
}
