error: failed to prepare transaction (could not satisfy dependencies)
:: installing libxml2 (2.14.2-2) breaks dependency 'libxml2.so=2-64' required by rest

rest should be an old package that has not been in the repos for a long time and on which no other package depends. You can safely remove it:

sudo pacman -R rest
