XML with comment gets indented incorrectly

[simonschaufi]

The problem is that the HTML comment get's detected as openingTag which is wrong.

<?xml version="1.0"?>
<config>
    <!-- comment -->
    <type>select</type>
</config>

will be printed like this:

<?xml version="1.0"?>
<config>
    <!-- comment -->
        <type>select</type>
    </config>
