The position should be counted for each nodeset but the previous
implementation counts position for union-ed nodeset.
For example, "/a/*/*[1]" should be matched to "<c1/>" and "<c2/>" with
the following XML.
<a>
<b>
<c1/>
</b>
<b>
<c2/>
</b>
</a>
But the previous implementation just returns only "<c1/>".
* lib/rexml/element.rb (REXML::Attributes#each_attribute):
Support Enumerator for no block use.
* lib/rexml/element.rb (REXML::Attributes#each):
Support Enumerator for no block use.
* lib/rexml/functions.rb (REXML::Functions.string):
Support NaN again.
* lib/rexml/xpath_parser.rb: Re-implement "Step" evaluator.
It should evaluate "AxisSpecifier", "NodeTest" and "Predicate" in one
step to respect position for each nodeset.
* test/rexml/test_jaxen.rb: Enable more tests. Remained tests should
be also enabled but it'll not be near future.
* test/rexml/xpath/test_base.rb: Fix expected value.
