XPath "//" doesn't work on cloned nodes

[yegor256]

This test doesn't work:

final XML xml = new XMLDocument("<t6><z9 a='433'/></t6>");
final XML root = xml.nodes("/t6").get(0);
MatcherAssert.assertThat(
  root.xpath("//z9/@a").get(0),
  Matchers.equalTo("433")
);

@yegor256 right, I added the bug tag

@yegor256 thanks for tis bug, I topped your account for 15 mins, transaction 000-6df0335a

@suseika please go ahead, it's your task now, keep this in mind, and don't hesitate to ask any technical questions you may have... The cost of this task is 30 mins (this is exactly how much will be paid, not less not more), when the task is done

[gvlasov]

@yegor256 Can you please clarify what exactly is the undesired behavior? In the test you pushed, an h9 node doesn't seem to be appended to a document.

[yegor256]

@Suseika see this test: 1bc7fc1 It fails, but it shouldn't, as I understand

[yegor256]

@Suseika this test works fine if we get rid of cloning. But we need cloning to preserve immutability

[gvlasov]

@yegor256 This issue's title speaks about XML#node() method, there is no XML#node() call in 1bc7fc1. I still don't see a way to reproduce the problem I'm assigned to, to me 1bc7fc1 looks like another problem.

[yegor256]

@Suseika you're right, I updated the description of the ticket and its title

[gvlasov]

@yegor256 Will you please check the PR?
