Late last week, Mac DevCenter Blog’s feeds went a little screwy. Mea culpa. I used an uppercase closing tag to match a lowercase opening tag.
Some feeds (in particular Atom 1.0) depend on valid xhtml so news readers will parse them correctly. Unfortunately MT does have any kind of HTML fixer/checker. So I ask our readers will the OS X command line xmllint –html work properly and consistently as a validator to help this problem?
