[jira] Commented: (ODE-663) DOMUtils.cloneNode results in invalid namespace declaration

["Mark Ford (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ODE-663?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865358#action_12865358 ] 

Mark Ford commented on ODE-663:
-------------------------------

Please see my comments above about the Saxon DOM being immutable. The fix is to traverse the dom and copy its nodes over individually. The previous code was fine but was likely missing an edge case. I recommend adding a unit test for the original bug report, stepping through the original code and fixing the issue.

> The DOMUtils.cloneNode code doesn't handle default namespace declarations correctly when processing an XQuery result from Saxon.
> For example:
> <ns1:parent xmlns:ns1="abc">
>    <ns1:child xmlns="def">
>       <ns2:nestedChild xmlns:ns2="def"/>
>    </ns1:child>
> </ns1:parent>
> results in:
> <ns1:parent xmlns:ns1="abc">
>    <ns1:child xmlns:xmlns="def">
>       <ns2:nestedChild xmlns:ns2="def"/>
>    </ns1:child>
> </ns1:parent>
> Notice that the default namespace has been rewritten as xmlns:xmlns which is invalid. 
> Granted the above example is a bit odd, but strange things can happen when passing nodes in and out of XSLT and XQuery with respect to namespace declarations.
