_aggregator_parse_opml($opml)

Parse an OPML file.

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

Parameters

$opml The complete contents of an OPML document.

Return value

An array of feeds, each an associative array with a <em>title</em> and a <em>url</em> 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.
