The enumerator is positioned on the current position of the XPathNodeIterator object.
There are two ways to iterate over an XPathNavigator collection by using the XPathNodeIterator class.
One way is to use MoveNext and then call Current to get the current XPathNavigator instance, as in the following example:
While nodeIterator.MoveNext()
Dim n As XPathNavigator = nodeIterator.Current
Console.WriteLine(n.LocalName)
End While
while (nodeIterator.MoveNext())
{
XPathNavigator n = nodeIterator.Current;
Console.WriteLine(n.LocalName);
}
while (nodeIterator->MoveNext())
{
XPathNavigator^ n = nodeIterator->Current;
Console::WriteLine(n->LocalName);
}
Another way is to use a foreach loop to call GetEnumerator and use the returned IEnumerator interface to enumerate the nodes, as in the following example:
For Each n As XPathNavigator In nodeIterator
Console.WriteLine(nav.LocalName)
Next
foreach (XPathNavigator n in nodeIterator)
Console.WriteLine(n.LocalName);
for each (XPathNavigator^ n in nodeIterator)
Console::WriteLine(n->LocalName);
You should either use MoveNext and Current or use GetEnumerator. Combining these two approaches can cause unexpected results. For example, if the MoveNext is called first, and then GetEnumerator is called in the foreach loop, the foreach loop will not start enumerating the results from the beginning of the collection, but from the position after the Current method.
