Overview
WWW::OpenSearch::Response is a module designed to encapsulate a response received from an A9 OpenSearch compatible engine. See http://opensearch.a9.com/spec/1.1/response/ for details.
Constructor
new( $response )
Constructs a new instance of WWW::OpenSearch::Response from the WWWW::OpenSearch:Response returned by the search request.
Methods
parse_response( )
Parses the content of the HTTP response using XML::Feed. If successful, parse_feed( ) is also called.
parse_feed( )
Parses the XML::Feed originally parsed from the HTTP response content. Sets the pager object appropriately.
previous_page( ) / next_page( )
Performs another search on the parent object, returning a WWW::OpenSearch::Response instance containing the previous/next page of results. If the current response includes a <link rel="previous/next" href="..." /> tag, the page will simply be the parsed content of the URL specified by the tag's href attribute. However, if the current response does not include the appropriate link, a new query is constructed using the startPage or startIndex query arguments.
_get_link( $type )
Gets the href attribute of the first link whose rel attribute is equal to $type.
Accessors
feed( )
pager( )
