Support alternative XML parsers besides SimpleXMLElement

[caseyamcl]

There are other ways of parsing XML responses from service providers. Make the response item handler optional (use raw output), or allow specifying a callback / handler interface to handle each record.

Since we are going to model the PHP OAI-PMH responses in v4, we'll push this to v4.

Would be great to have an iterator returning XML strings instead of SimpleXMLElements.

I have also a similair question. We are importing an RDF formatted and the $xml is not returning the full metadata. How can we solve this problem?

FWIW, I've found the sabre xml parser to be easy to work with: https://sabre.io/xml/

Just sharing one problem that I had, which is somehow related to this issue, at this point:

phpoaipmh/src/RecordIterator.php

Line 198 in 89b38d8

$this->currItem = clone $item;

A single node is being cloned and retrieved, but the whole XML context is kept alive/carried on. Therefore, a generic XPath query such as //dc:date will bring nodes from all records.
