Re: [bdbxml] Beginners question with Perl

Peter,

The error indicates that the problem is not in the query, but in
the parsing of a document during the query.

Do your documents reference external entities/DTDs?
In your function that creates the XmlManager, add the
flag, DBXML_ALLOW_EXTERNAL_ACCESS to the
constructor, and see if that helps.

A way to avoid pathname/directory issues in queries
is to add aliases for containers once they are opened.
See XmlContainer::addAlias() for usage.  Aliases
can then be used in query expressions.  This feature isn't
your direct issue, but it sounds like you could use it.

Regards,

George
