  Start tag expected, '<' not found
is a parser error, not a validation error. So your callback on validation
error does not catch it.
What you need to do really depends on the kind of use, there are various
ways to catch errors in libxml2 which may or may not be suitable.
Try 
    http://xmlsoft.org/html/libxml-xmlerror.html#xmlSetStructuredErrorFunc
or
    http://xmlsoft.org/html/libxml-xmlerror.html#xmlSetGenericErrorFunc
