DOMXPath::query(): Undefined namespace prefix

[peter279k]

Test branch: develop.
Please consider the following error output:

PhpOffice\Common\Tests\XMLReaderTest::testShouldThrowExceptionIfNamespaceIsNotKnown
DOMXPath::query(): Undefined namespace prefix

And it seems that this test will be broken when executing the $this->xpath->query($path);.
Please see more details about this Travis build log.

Thanks.

That's strange, the test indeed checks that an exception is thrown.

expecting the following works, at least for php 7.2.

    /**
     * @expectedException PHPUnit_Framework_Error
     */

I'm not sure about other versions though
