OpmlFeedAdd::parseOpml

protected OpmlFeedAdd::parseOpml($opml)

Parses an OPML file.

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

@todo Move this to a parser in https://www.drupal.org/node/1963540.

Parameters

string $opml: The complete contents of an OPML document.

Return value

array 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.
