function _aggregator_parse_opml

Parses an OPML file.

Feeds are recognized as <outline> elements with the attributes "text" and "xmlurl" set.

Parameters

$opml: The complete contents of an OPML document.

Return value

An array of feeds, each an associative array with a "title" and a "url" element, or NULL if the OPML document failed to be parsed. An empty array will be returned if the document is valid but contains no feeds, as some OPML documents do.
