+# Variable Resolvers
+
+The methods on the [XPathEvaluator](#) type can optionally take a variable resolver to resolve 
+variable references in the XPath expression being evaluated.
+
+There are three ways to specify a variable resolver and you can use any one of them depending on which is 
+most suited to your particular situation.
+
+Note that if your variables are in a namespace (e.g. `$myVars:var`), you must use the second or third 
+type as the plain object implementation does not support namespaces.
+
+## Variable values
+
+You can use any of five types of values to specify the values of variables:
+
+- string
+- number
+- boolean
+- single node (will be treated as a node set)
+- array of nodes or array-like collection of nodes (will be treated as a node set)
+
+## Variable Resolver Type 1: Plain object
+
+A plain object with variable names as the keys and variable values as the values.
+
+Example usage:
+
+````
+var evaluator = xpath.parse('concat($character1, ", ", $character2, ", and ", $character3)');
+var mainCharacters = evaluator.evaluateString({
+	variables: {
+		character1: 'Harry',
+        character2: 'Ron',
+        character3: 'Hermione'
+	}
+});
+````
+
+## Variable Resolver Type 2: Function
+
+A function that takes a variable name as its first parameter and an optional namespace URI as its second parameter 
+and returns a value based on the name and namespace.
+
+Example usage:
+
+````
+var evaluator = xpath.parse('concat($hp:character1, ", ", $hp:character2, ", and ", $hp:character3)');
+var mainCharacters = evaluator.evaluateString({
+	variables: function (name, namespace) {
+        if (namespace === 'http://sample.org/harrypotter/') {
+            switch (name) {
+                case 'character1': return 'Harry';
+                case 'character2': return 'Ron';
+                case 'character3': return 'Hermione';
+            }
+        }
+	},
+    namespaces: {
+        hp: 'http://sample.org/harrypotter/'
+    }
+});
+````
+
+## Function Resolver Type 3: Object with `getFunction` method
+
+An object with a method named `getVariable` that works in the same way as the function-based variable resolver 
+described above.
+
+Example usage:
+
+````
+var evaluator = xpath.parse('concat($hp:character1, ", ", $hp:character2, ", and ", $hp:character3)');
+var mainCharacters = evaluator.evaluateString({
+	variables: {
+        getVariable: function (name, namespace) {
+            if (namespace === 'http://sample.org/harrypotter/') {
+                switch (name) {
+                    case 'character1': return 'Harry';
+                    case 'character2': return 'Ron';
+                    case 'character3': return 'Hermione';
+                }
+            }
+	    }
+    },
+    namespaces: {
+        hp: 'http://sample.org/harrypotter/'
+    }
+});
+````
