Below is my code for parsing a remote .rss file. I have uploaded this to my server I get zero errors but the data is not displayed. I cant find the misconfiguration that is eluding me, perhaps another pair of eyes will help, having a fresh view of it. Any help is appreciated, thank you.
Here is the code:
<?php
mysql_connect ("localhost", "techa_admin", "reaper") or die ('I cannot connect to the database.');
mysql_select_db ("techa_");
class xItem {
var $xTitle;
var $xLink;
var $xDescription;
}
// general vars
$sTitle = "";
$sLink = "";
$sDescription = "";
$arItems = array();
$itemCount = 0;
// ****** Start User-Defined Vars ******
// rss url goes here
$uFile = "http://www.camelotherald.com/xml/news.rss";
// descriptions (true or false) goes here
$bDesc = true;
// font goes here
$uFont = "Verdana, Arial, Helvetica, sans-serif";
$uFontSize = "2";
// *** End User-Defined Vars ***********
function startElement($parser, $name, $attrs) {
global $curTag;
$curTag .= "$name";
}
function endElement($parser, $name) {
global $curTag;
$caret_pos = strrpos($curTag,'');
$curTag = substr($curTag,0,$caret_pos);
}
function characterData($parser, $data) { global $curTag; // get the Channel information first
global $sTitle, $sLink, $sDescription;
$titleKey = "RSSCHANNELTITLE";
$linkKey = "RSSCHANNELLINK";
$descKey = "RSSCHANNELDESCRIPTION";
if ($curTag == $titleKey) {
$sTitle = $data;
}
elseif ($curTag == $linkKey) {
$sLink = $data;
}
elseif ($curTag == $descKey) {
$sDescription = $data;
}
// now get the items
global $arItems, $itemCount;
$itemTitleKey = "RSSCHANNELITEMTITLE";
$itemLinkKey = "RSSCHANNELITEMLINK";
$itemDescKey = "RSSCHANNELITEMDESCRIPTION";
if ($curTag == $itemTitleKey) {
// make new xItem
$arItems[$itemCount] = new xItem();
// set new item object's properties
$arItems[$itemCount]->xTitle = $data;
}
elseif ($curTag == $itemLinkKey) {
$arItems[$itemCount]->xLink = $data;
}
elseif ($curTag == $itemDescKey) {
$arItems[$itemCount]->xDescription = $data;
// increment item counter
$itemCount++;
}
}
// main loop
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
