Re: [ptp-dev] Problem with XML input to JAXB parser for PE resource mana

["Albert L. Rossi" <arossi@xxxxxxxxxxxxx>]

You know, the more I think of this, the more I think something else is fishy.  Technically the validator should consider
<x></x>
and
<x/>
equivalent.

What platform are you using?  Windows, perhaps?

There is no easy way to do this in the validator except by catching the exception, checking the message and then turning it into a warning if it matches the message concerning empty children.  However, this message is used indiscriminately for cases where there are empty strings, non-empty strings and actual child elements where there shouldn't be, so if I did this, I'd be throwing out the baby with the bath and not throwing legitimate validation exceptions in the other cases.
