ZF2 Xpath validator

This is a simple ZF2 componente that will validate that an Xpath expression is valid, not that it will return certain data. Checkout the test cases to see how to use it.

Or, look here:

$validator = new \Magium\Validate\Xpath\XpathValidator();
$validator->isValid('//div'); // returns true

or

$validator = new \Magium\Validate\Xpath\XpathValidator();
$validator->isValid('invalid xpath'); // returns false
