Thanks for detailed reporting and providing a fix with an unit test.
> Xtokenize does not track a level up again once it detects a non matching

> Key: CAMEL-16865
> URL: https://issues.apache.org/jira/browse/CAMEL-16865
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 3.11.1
> Reporter: Ruben Gerits
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 3.7.6, 3.11.2, 3.12.0

>
> 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}
