-Subject: [PATCH] Work around lxml API abuse
-
-Make xmlNodeDumpOutput and htmlNodeDumpFormatOutput work with corrupted
-parent pointers. This used to work with the old recursive code but the
-non-recursive rewrite required parent pointers to be set correctly.
-
-Unfortunately, lxml relies on the old behavior and passes subtrees with
-a corrupted structure. Fall back to a recursive function call if an
-invalid parent pointer is detected.
-
-Fixes #255.
-
-Upstream-Status: Backport [85b1792e37b131e7a51af98a37f92472e8de5f3f]
