ISOBMFF conformance suite issue

[podborski]

This one is similar to #1940

I noticed that the xml dump of file with a CompactSampleGroupBox results in invalid xml where Pattern tags are never closed.

How to reproduce:

curl https://conformance.mpeg.expert/ISOBMFF/under_consideration/compact_sample_groups/samplegroups_defrag_compact.mp4 -O
MP4Box -diso samplegroups_defrag_compact.mp4

run xml validator on samplegroups_defrag_compact_info.xml

Used MP4Box - GPAC version 1.1.0-DEV-rev1632-gf2fddd04-master

btw. is there a way to automate xml validation checks? Could be useful to identify those types of issues when dumping the xml.

Good idea, now possible using:

MP4Box -check-xml -diso source

Works for diso, dnal and dxml, the command will fail if XML parsing fails.
