Hello,
I use the parser in non-validating mode and want it to continue after
an IOException is thrown during attempt to open an external entity (
check for its reachability). Parser should recover from such state in
non-validating mode even if scanning of external entities is enabled.
An attached patch fixes the behaviour by reporting a warning.
It means that parser throws IOException (that moves parsing to
unrecoverable state) only if it can not fetch data from already
opened entity stream.
Does it make sense? I hope so.
Is there a better solution? I do not know.
Cc.
