That is because you have an invalid expression, at least in XPath 1.0
which is all that libxml2 supports at this point, you cannot use the
syntax above, you would have to use, say, a node test with a predicate
like in `*[self::one or self::two]` for instance. See the definition
<http://www.w3.org/TR/xpath/#NT-Step>.
