Which one is "quicker", using a string or SelectSingleNode? ?
I need to use some field "ID" a couple of times in loop, say for example 4 times in a loop, which one of these code would be faster ?
Code:
foreach(XmlNode XMLNODE in XML_menu.SelectSingleNode("menu").ChildNodes){
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );
}
or
Code:
foreach(XmlNode XMLNODE in XML_menu.SelectSingleNode("menu").ChildNodes){
string ID = XMLNODE.SelectSingleNode("@id").InnerText;
Console.WriteLine( ID );
Console.WriteLine( ID );
Console.WriteLine( ID );
Console.WriteLine( ID );
}
What I mean is, is it faster to you "XMLNODE.SelectSingleNode" many times or should I first get its value into some string and then use that string many times?
