Hi,
I'm seeing a problem with using the Factory parse() method corrupting
after it sees malformed XML. For example, I have a web service that
receives XML over an HTTP POST, and uses Xmlbeans to parse the XML. I
use the parse() method that takes a String.
When I send an intentionally invalid XML string to the service, it
produces Error #1 below. The XML I send is:
<?xml verion="1.0" ?>
<request clientId="1234" clientKey="5678">
<message>Test message</message>
</request>
Notice that the XML declaration has "verion" instead of "version"
(missing the "s"). When I correct the XML and send the following, the
parse() method succeeds half the time and fails (with Error #2 below)
half the time. The successes and failures exactly alternate.
<?xml version="1.0" ?>
<request clientId="1234" clientKey="5678">
<message>Test message</message>
</request>
Has anyone seen a similar behavior? Is there any way to tell the
document factory to dispose of it's digesters and create new ones if
there is an error while parsing?
Thanks,
Garth
