+# Namespace Resolvers
+
+The methods on the [XPathEvaluator](XPathEvaluator.md) type can optionally take a namespace resolver to resolve 
+namespace references in the XPath expression being evaluated.
+
+There are three ways to specify a namespace resolver and you can use any one of them depending on which is 
+most suited to your particular situation.
+
+## Namespace Resolver Type 1: Plain object
+
+A plain object with namespace prefixes as the keys and namespace URIs as the values:
+
+Example usage:
+
+```js
+var evaluator = xpath.parse('/bk:book/hp:characters');
+var characters = evaluator.select({
+    node: myBookNode,
+    namespaces: {
+        'bk': 'http://sample.org/books/',
+        'hp': 'http://sample.org/harrypotter/'
+    }
+});
+```
+
+## Namespace Resolver Type 2: Function
+
+A function that takes a namespace prefix as a parameter and returns the corresponding namespace URI. 
+
+Example usage:
+
+```js
+var evaluator = xpath.parse('/bk:book/hp:characters');
+var characters = evaluator.select({
+    node: myBookNode,
+    namespaces: function (prefix) {
+        if (prefix === 'bk') {
+            return 'http://sample.org/books/';
+        }
+        if (prefix === 'hp') {
+            return 'http://sample.org/books/';
+        }
+    }
+});
+```
+
+## Namespace Resolver Type 3: Object with `getNamespace` method
+
+An object with a method named `getNamespace` that works in the same way as the function-based namespace resolver 
+described above.
+
+Example usage:
+
+```js
+var evaluator = xpath.parse('/bk:book/hp:characters');
+var characters = evaluator.select({
+    node: myBookNode,
+    namespaces: {
+        getNamespace: function (prefix) {
+            if (prefix === 'bk') {
+                return 'http://sample.org/books/';
+            }
+            if (prefix === 'hp') {
+                return 'http://sample.org/books/';
+            }
+        }
+    }
+});
+```
