|
||||
* rssparse.php3 is a small PHP script for parsing RDF/RSS XML data. It has been
|
||||
* tested with a number of popular web news and information sites such as
|
||||
* slashdot.org, lwn.net, and freshmeat.net. This is not meant to be exhaustive
|
||||
* but merely to provide the basic necessities. It will grow in capabilities with
|
||||
* time, I'm sure.
|
||||
*
|
||||
* This is code I wrote for Nerds WithOut Wires, http://nwow.org.
|
||||
*
|
||||
*
|
||||
* USAGE:
|
||||
* In your PHP script, simply do something akin to this:
|
||||
*
|
||||
* include("rssparse.php3");
|
||||
* $fp = fopen("file", "r");
|
||||
* $rss = rssparse($fp);
|
||||
*
|
||||
* if (!$rss) {
|
||||
* ERROR;
|
||||
* }
|
||||
*
|
||||
* while (list(,$item) = each($rss->items)) {
|
||||
* printf("Title: %s\n", $item["title"]);
|
||||
* printf("Link: %s\n", $item["link"]);
|
||||
* printf("Description: %s\n", $item["desc"]);
|
||||
* }
|
||||
*
|
||||
* printf("Channel Title: %s\n", $rss->title);
|
||||
* printf("Channel Description: %s\n", $rss->desc);
|
||||
* printf("Channel Link: %s\n", $rss->link);
|
||||
*
|
||||
* printf("Image Title: %s\n", $rss->image["title"]);
|
||||
* printf("Image URL: %s\n", $rss->image["url"]);
|
||||
* printf("Image Description: %s\n", $rss->image["desc"]);
|
||||
* printf("Image Link: %s\n", $rss->image["link"]);
|
||||
*
|
||||
*
|
||||
* CHANGES:
|
||||
* 0.4 - rssparse.php3 now supports the channel image tag and correctly supports
|
||||
* RSS-style channels.
|
||||
*
|
||||
*
|
||||
* BUGS:
|
||||
* Width and height tags in image not supported, some other tags not supported
|
||||
* yet.
|
||||
*
|
||||
*
|
||||
* IMPORTANT NOTE:
|
||||
* This requires PHP's XML routines. You must configure PHP with --with-xml.
