Thanks for noticing this, I see libxml-sax-perl gets pulled by
libxml-simple-perl; one of the packages libxml-libxml-perl or
libxml-sax-expat-perl is supposed to get installed aside, but
for some reason, the PurePerl implementation remains top
priority within an sbuild environment. Under normal
circumstances, there would be a debconf prompt to resolve the
selection of the default parser, but in sbuild context the
default sticks rather hard to the PurePerl implementation.
For some reason, after a successful build, the autopkgtest
environment does not seem to suffer from the inappropriate
choice though; this is independent of the backend, whether it is
schroot or unshare. I'm afraid I'm at loss understanding the
update-perl-sax-parsers behavior.
I took inspiration from David's selection based on environment
variables and this seems to be sufficient to get the package
back on tracks:

I believe it should be good enough to resolve the bug without
further issues and will upload this evening.
Have a nice day, :)
