Subject: Returning documents from XPath extension functions
Date: Fri, 6 Dec 2019 16:24:17 +0100
To: bug-XML-LibXSLT [...] rt.cpan.org
From: Nick Wellnhofer <wellnhofer [...] aevum.de>
The code in LibXSLT__function which handles XPath extension functions wraps returned nodes in another document for memory management reasons. If one of the returned nodes happens to be a document node, the document will be wrapped inside another document. This violates libxml2's assumption that document nodes can only be at the root of a tree and can lead to issues like https://gitlab.gnome.org/GNOME/libxml2/issues/132 The cleanest solution is to copy the document's children to the RVT and return the RVT in the result node list.
