Bill Venners has posted the final installment of his interview with me about XML and XOM at last year's Software Development West conference. In this piece, I discuss how to handle invalid documents.
Sam Tregar has released XML::Validator::Schema 1.04, a Perl module that validates XML documents against a partial subset of the W3C XML schema language. It is implemented as a SAX filter on top of XML::SAX. 1.04 adds support for minOccurs and maxOccurs with sequence, choice, and all groups.
