示例1: Evaluate
// Invoked from XsltKey (XPathFunction)
public BaseIterator Evaluate (BaseIterator iter,
Expression valueExpr)
{
XPathNodeIterator i = iter;
if (iter.CurrentPosition == 0) {
i = iter.Clone ();
i.MoveNext ();
}
XPathNavigator nav = i.Current;
object o = valueExpr.Evaluate (iter);
XPathNodeIterator it = o as XPathNodeIterator;
XsltContext ctx = iter.NamespaceManager as XsltContext;
BaseIterator result = null;
if (it != null) {
while (it.MoveNext()) {
ArrayList nodes = GetNodesByValue (
nav, it.Current.Value, ctx);
if (nodes == null)
continue;
ListIterator tmp =
new ListIterator (nodes, ctx);
if (result == null)
result = tmp;
else
result = new UnionIterator (
iter, result, tmp);
}
}

ArrayList nodes = GetNodesByValue (
nav, XPathFunctions.ToString (o), ctx);
if (nodes != null)

}示例2: Evaluate
public override object Evaluate (BaseIterator iter)
{
if (iter.CurrentPosition == 0) {
iter = (BaseIterator) iter.Clone ();
iter.MoveNext ();
}
XPathNavigator navRoot = iter.Current.Clone ();
navRoot.MoveToRoot ();
return new SelfIterator (navRoot, iter.NamespaceManager);
