Well, if you're tired of typing XPathNavigator all the time, you can create an alias for it. Just put this under the other using statements at the top of the file:

using XPN = System.Xml.XPath.XPathNavigator;

Now you can use

XPN root = MainDataSource.CreateNavigator();

Also, it's not actually necessary to type MainDataSource here. All you need is CreateNavigator(), so now you're down to this:

XPN root = CreateNavigator();

Also, you can add a function like this:

XPathNavigator GetNode(XPathNavigator start, string path)
{
return start.SelectSingleNode(path, NamespaceManager);
}

And thanks to that, you can replace that second line you have there with:

string RegionName = GetNode(root, xpathRegName).Value;

Is that any better?

const, string and other variables

I have been using a bunch of c#, in order to keep the code clean and neat I have started pulling out my xpaths and declaring as const string. One addition item I am using over and over again is converting this

string RegionName = MainDataSource.CreateNavigator().SelectSingleNode(xpathRegName, NamespaceManager).Value;

to this

XPathNavigator root = MainDataSource.CreateNavigator();
string RegionName = root.SelectSingleNode(xpathRegName, NamespaceManager).Value;

the problem is I have to write the XPathNavigator in every function. is there a way to write this once and use it many times?

XPathNavigator root = MainDataSource.CreateNavigator();
