Handle closing tag with whitespace

[ashabhasa]

This PR fixes a problem when parsing xml documents that have closing tags with trailing whitespace:

<foo>some-data</foo >

Thank you that was an interesting fix. Could you please try out the following test case?

<foo>DATA</foo   bar >

and help to ensure that it fails :)

Thank you for the feedback, I've added a test that makes sure the parsing fails when a node like the following is present

<foo>DATA</foo   bar >
