Usage example
=============

[](#usage-example)

```
use alcamo\xpointer\Pointer;

$doc = new \DOMDocument();

```

... load something into the document ...

```
$urlFragment = 'xmlns(f=http://foo.example.org) xpointer(/*/f:bar[42])';

$pointer = new Pointer($urlFragment);

```

The following evaluates the XPath `/*/f:bar[42]` on the document, where the prefix `f` is registered as the namespace `http://foo.example.org`:

```
$bar = $pointer->process($doc);

```

Supplied interfaces and classes
===============================

[](#supplied-interfaces-and-classes)

Interface `PointerInterface`
----------------------------

[](#interface-pointerinterface)

Simple interface for classes that implement a [Pointer](https://www.w3.org/TR/xptr-framework/#dt-pointer). Requires a static factory method to create a Pointer from an URL fragment string and a method to process the pointer on a DOM document.

Class `Pointer`
---------------

[](#class-pointer)

Implementation of `PointerInterface` supporting [Shorthand Pointers](https://www.w3.org/TR/xptr-framework/#shorthand) as well as the [XPointer xmlns() Scheme](https://www.w3.org/TR/xptr-xmlns/) and [XPointer xpointer() Scheme](https://www.w3.org/TR/xptr-xpointer/).

Interface `PartInterface`
-------------------------

[](#interface-partinterface)

Simple interface for classes that implement a [Pointer part](https://www.w3.org/TR/xptr-framework/#dt-pointerpart). Requires just a `process()` method to process the [Scheme data](https://www.w3.org/TR/xptr-framework/#syntax). Processing of parts stops as soon as this method return a non-`null` value.

Class `XmlnsPart`
-----------------

[](#class-xmlnspart)

Implementation of `PartInterface` for the [XPointer xmlns() Scheme](https://www.w3.org/TR/xptr-xmlns/). The `process()` method modifies the namespace bindings as described in the specification.

Class `XpointerPart`
--------------------

[](#class-xpointerpart)

Implementation of `PartInterface` for the [XPointer xpointer() Scheme](https://www.w3.org/TR/xptr-xpointer/). The `process()` method returns the result of XPath evaluation, if successful.

Extending this package
======================

[](#extending-this-package)

To add other XPointer schemes:

1. Write a new pointer part class that implements `PartInterface`.
2. Write a class derived from `Pointer` and add your new pointer part class to the class constant `SCHEME_MAP`.
