I couldn't find a better resource for reporting a possible .NET Framework 1.1
(SP0 & 1) bug, so if this is not the proper forum, please let me know.
The problem appears to occur when using "self::" to match the current node
of an XPathNavigator. In this case the resulting XPathNodeIterat or returns a
Count of 1 even though it is properly empty as evidenced by MoveNext()
returning false.
In the following sample code (compiled as a console program), the results
from Test 2 & 10 are not correct.
static void Main(string[] args)
{
XPathDocument doc = new XPathDocument(n ew
StringReader("< root><a></a></root>"));
XPathNavigator nav = doc.CreateNavig ator();
nav.MoveToFirst Child(); // now at "root"
Console.Out.Wri teLine("Current Node Name: {0}\n",nav.Name );
RunSelectTest(n av,"self::root" ,1);
RunSelectTest(n av,"self::nomat ch",2);
RunSelectTest(n av,"../root",3);
RunSelectTest(n av,"../nomatch",4);
RunSelectTest(n av,"a/self::a",5);
RunSelectTest(n av,"a/self::nomatch", 6);
RunSelectTest(n av,"a",7);
RunSelectTest(n av,"nomatch",8) ;
nav.MoveToFirst Child(); // now at "a"
RunSelectTest(n av,"self::a",9) ;
RunSelectTest(n av,"self::nomat ch",10);
}
static void RunSelectTest( XPathNavigator nav, string xpath, int testId )
{
Console.Out.Wri teLine("--- Test {0} (\"{1}\") ---",testId,xpath) ;
XPathNodeIterat or iter = nav.Select(xpat h);
Console.Out.Wri teLine("Select Iter Count: {0}",iter.Count );
Console.Out.Wri teLine("Select Iter MoveNext: {0}",iter.MoveN ext());
Console.Out.Wri teLine(string.E mpty);
}
