From 9faa31ce79f1f63ba091a9a8edd8b7c54395ee10 Mon Sep 17 00:00:00 2001 From: Tim Wiederhake Date: Wed, 30 Sep 2020 13:55:02 +0200 Subject: [PATCH] util: Allow validation for single XML node Validation is usually performed on an entire document. If we are only interested in validating a single nested node that can occur in different contexts, this would require writing different schemas for any of those different contexts. By temporarily replacing the document's root node, we can validate the relevant node only.
