gerits opened a new pull request #5955:
URL: https://github.com/apache/camel/pull/5955
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:
```
<?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>
```
And we run the xtokenize expression as following (within test class
`XMLTokenExpressionIteratorTest`):
```
nsmap.put("X", "urn:x");
invokeAndVerify("//G:grandparent/X:*",
'i', new ByteArrayInputStream(TEST_BODY_MIXED_CHILDREN),
RESULTS_AUNT_AND_UNCLE);
```
As a result we now get:
```
<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>
```
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:
```
<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>
```
- [x] Make sure there is a [JIRA
issue](https://issues.apache.org/jira/browse/CAMEL) filed for the change
(usually before you start working on it). Trivial changes like typos do not
require a JIRA issue. Your pull request should address just this issue,
without pulling in other changes.
- [x] Each commit in the pull request should have a meaningful subject line
and body.
- [x] If you're unsure, you can format the pull request title like
`[CAMEL-XXX] Fixes bug in camel-file component`, where you replace `CAMEL-XXX`
with the appropriate JIRA issue.
- [x] Write a pull request description that is detailed enough to understand
what the pull request does, how, and why.
- [x] Run `mvn clean install -Psourcecheck` in your module with source check
enabled to make sure basic checks pass and there are no checkstyle violations.
A more thorough check will be performed on your pull request automatically.
