If the data source declares a default namespace (e.g., <OAI-PMH xmlns="http://www.openarchives.org/OAI/2.0/">), this must be assigned a non-empty prefix using registerXPathNamespace() in order for it to be accessible through the xpath() function.

For discussion, see for instance: http://www.perlmonks.org/?node_id=530519.

The attached patch allows setting a prefix to solve this issue.

    These should be somewhere after the constructor and have some documentation.
