Solved a problem of xmltextreader usage, endelement

As follows, none of the examples found on codeguru or codeproject process such a situation:
<A name = "test"/> is the case where no </a> label exists. In this case, processing element a will not encounter endelement.
Here we make a process to determine its depth. Xmltextreader reader = NULL;
Try
{
Reader = new xmltextreader (streamreader );
Startdocument (); // start Analysis

Int dept =-1;
While (reader. Read ())
{
Switch (reader. nodetype)
{
Case xmlnodetype. element:
Hashtable attributes = new hashtable ();
String struri = reader. namespaceuri;
String strname = reader. Name;
If (reader. hasattributes)
{
For (INT I = 0; I <reader. attributecount; I ++)
{
Reader. movetoattribute (I );
Attributes. Add (reader. Name, reader. value );
}
}
Startelement (struri, strname, strname, attributes );
If (Dept! =-1 & reader. depth <= Dept) // process "/>" tags
Endelement (string. Empty, reader. Name, String. Empty );
Dept = reader. depth;
Break;
Case xmlnodetype. endelement:
Endelement (string. Empty, reader. Name, String. Empty );
Break;
Case xmlnodetype. Text:
Characters (reader. value );
Break;
Default:
Break;
}
}
Return (namespace) objectstack. Pop ();
}
Catch (xmlexception E)
{
Console. writeline ("error occured:" + E. Message );
}
Finally
{
If (reader! = NULL) reader. Close ();
}
