What problem are you trying to solve?

There is a critical vulnerability in the xmldom package (See GHSA-crh6-fp67-6883)
And the xmldom package won't be updated (see xmldom/xmldom#271), only @xmldom/xmldom is maintained so for future security patches, it would also be better to use @xmldom/xmldom

Describe the solution you'd like

Update to @xmldom/xmldom@~0.7.7, @xmldom/xmldom@~0.8.4 (dist-tag latest) or @xmldom/xmldom@>=0.9.0-beta.4 (dist-tag next).
A PR is currently opened here #1698 but it seems like no one took a look at it and a lot of tests are failing. I have completed the changes in #1711
