Plugins/Packages: add missing format string parameter
Revert "Avoid use of lxml-only getparent()"

This reverts commit 38f55b6257ce51b1cf65ecb3d980d7528c1b53ff.
Client/Frame: avoid use of lxml-only getparent()

getparent is not supported by xml.etree so try to emulate it
with a generated parent_map. This is the only possibility, because
xml.etree does not store references to the parent elements.
