> When trying to find all items of a specific namespace within a parent tag it will stop detecting the children once it comes across a parent tag that does not have any child elements within this namespace. 
> It seems that the code to go up a level again is only triggered once a matching child element has been found. If no elements are found this logic is not triggered, even though the xml tag ends at that level.
> For example having XML:
> {code:xml}
> <?xml version='1.0' encoding='UTF-8'?>
> <greatgrandparent xmlns='urn:g' xmlns:c='urn:c' xmlns:x='urn:x'>
>     <grandparent>
>         <x:uncle>bob</x:uncle>
>         <x:aunt>emma</x:aunt>
>     </grandparent>
>     <grandparent>
>         <c:parent some_attr='1'>
>             <c:child some_attr='a' anotherAttr='a'></c:child>
>             <c:child some_attr='b' anotherAttr='b' />
>         </c:parent>
>         <c:parent some_attr='2'>
>             <c:child some_attr='c' anotherAttr='c'></c:child>
>             <c:child some_attr='d' anotherAttr='d' />
>         </c:parent>
>     </grandparent>
>     <grandparent>
>         <x:uncle>ben</x:uncle>
>         <x:aunt>jenna</x:aunt>
>         <c:parent some_attr='3'>
>             <c:child some_attr='e' anotherAttr='e'></c:child>
>             <c:child some_attr='f' anotherAttr='f' />
>         </c:parent>
>     </grandparent>
> </greatgrandparent>
>  {code}
> And we run the xtokenize expression as following (within test class {{XMLTokenExpressionIteratorTest}}):
> {code:java}
> nsmap.put("X", "urn:x");
> invokeAndVerify("//G:grandparent/X:*",
>         'i', new ByteArrayInputStream(TEST_BODY_MIXED_CHILDREN), RESULTS_AUNT_AND_UNCLE);
> {code}
> As a result we now get:
> {code:xml}
> <x:uncle xmlns=\"urn:g\" xmlns:x=\"urn:x\" xmlns:c=\"urn:c\">bob</x:uncle>
> <x:aunt xmlns=\"urn:g\" xmlns:x=\"urn:x\" xmlns:c=\"urn:c\">emma</x:aunt>
> {code}
> This means it stops processing at the moment it got to the grandparent tag that only has {{<c:child>}} elements.
> The expected result would be:
> {code:xml}
> <x:uncle xmlns=\"urn:g\" xmlns:x=\"urn:x\" xmlns:c=\"urn:c\">bob</x:uncle>
> <x:aunt xmlns=\"urn:g\" xmlns:x=\"urn:x\" xmlns:c=\"urn:c\">emma</x:aunt>
> <x:uncle xmlns=\"urn:g\" xmlns:x=\"urn:x\" xmlns:c=\"urn:c\">ben</x:uncle>
> <x:aunt xmlns=\"urn:g\" xmlns:x=\"urn:x\" xmlns:c=\"urn:c\">jenna</x:aunt>
> {code}
