RSS Feed help pls

[BoarderLine]

Hi all, Please help.  I am using the following code in the attempt to display an RSS Feed on my site that will scroll text (left to right) along the top of the page.  The code works in displaying the feed however I am unsure how to get this to scroll a single line of text??? Any ideas cause im null :-(

 

<?

$MAXLINKCOUNT = 10; // (* 2) if =10, 5 news items will show
$MAX_DESC_CHARS = 120;

$insideitem = false;
$tag = "";
$title = "";
$description = "";
$link = "";
$linkcount = 0;

function startElement($parser, $name, $attrs) {
global $insideitem, $tag, $title, $description, $link;
if ($insideitem) {
$tag = $name;
} elseif ($name == "ITEM") {
$insideitem = true;
}
}

function endElement($parser, $name) {

global $insideitem, $tag, $title, $description, $link, $linkcount, $MAXLINKCOUNT, $MAX_DESC_CHARS;
if ($name == "ITEM" && $linkcount <= $MAXLINKCOUNT) {
if (strlen($description) > $MAX_DESC_CHARS) {
$description = wordwrap($description, $MAX_DESC_CHARS, "-=CUT OFF HERE=-");
$pos = strpos($description, "-=CUT OFF HERE=-");
$description = trim(substr($description, 0, $pos)) . "...";
}
$description = htmlspecialchars(trim($description));
$description = str_replace("&quot;", """, $description);
printf("<dt><b><a href='%s'>%s</a></b></dt>", trim($link),htmlspecialchars(trim($title)));
printf("<dt>%s</dt><br>",$description);
$title = "";
$description = "";
$link = "";
$insideitem = false;
}
}

function characterData($parser, $data) {
global $insideitem, $tag, $title, $description, $link, $linkcount;
if ($insideitem) {
switch ($tag) {
case "TITLE":
$title .= $data;
break;
case "DESCRIPTIon":
$description .= $data;
break;
case "LINK":
$link .= $data;
$linkcount++;
break;
}
}
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
$fp = fopen("--enter url for news feed here--","r")
or die("Error reading rss data.");
while ($data = fread($fp, 2048)) {
xml_parse($xml_parser, $data, feof($fp));
}
fclose($fp);
xml_parser_free($xml_parser);

?>

I believe you will need to use javascript for scrolling or dare I say a marquee tag.

any ideas on how this can be used to display more than one feed?

Really you should be using PHP 5's built in support of XML and RSS stuff.  It will drastically reduce the lines of code you use plus cure any headaches and gray hair you may get from the way you are doing it now.

 

 

I dug up this from back-in-the-day, its way basic, but it will give you a good starting point.  php.net is your friend
