Retrieve news from Linux Today
I would love to take the credit for this script but it is fact based on one I found in Beginning PHP 4 from wrox , which is an excellent PHP book.
Here is the code
<?php
if( ! ($fp = fopen("http://linuxtoday.com/backend/biglt.rss" , "r" )) )
die("Couldn't open xml file!");
$item_counter = 0;
$in_item_tag = 0;
$lintod_current_tag_state = '';
$lintod_headline_data = array();
function startElementHandler( $parser, $element_name, $element_attribs )
{
global $item_counter;
global $in_item_tag;
global $lintod_current_tag_state;
global $lintod_headline_data;
if( $element_name == "ITEM" )
{
$in_item_tag = 1;
}
if( $in_item_tag == 1 )
{
$lintod_current_tag_state = $element_name;
}
else
{
$lintod_current_tag_state = '';
}
}
function endElementHandler( $parser, $element_name )
{
global $item_counter;
global $in_item_tag;
global $lintod_current_tag_state;
global $lintod_headline_data;
$lintod_current_tag_state = '';
if( $element_name == "ITEM" )
{
$item_counter++;
$in_item_tag = 0;
}
}
function characterDataHandler( $parser , $data )
{
global $item_counter;
global $in_item_tag;
global $lintod_current_tag_state;
global $lintod_headline_data;
if( $lintod_current_tag_state == '' || $in_item_tag == 0 )
return;
if( $lintod_current_tag_state == "TITLE" ) {
$lintod_headline_data[$item_counter]["title"] = $data;
}
if( $lintod_current_tag_state == "LINK" ) {
$lintod_headline_data[$item_counter]["link"] = $data;
}
if( $lintod_current_tag_state == "DESCRIPTION" ) {
$lintod_headline_data[$item_counter]["description"] = $data;
}
}
if( !($xml_parser = xml_parser_create()) )
die("Couldn't create XML parser!");
xml_set_element_handler($xml_parser, "startElementHandler", "endElementHandler");
xml_set_character_data_handler( $xml_parser , "characterDataHandler" );
while( $data = fread($fp, 4096) )
{
if( !xml_parse($xml_parser, $data, feof($fp)) )
{
break; // get out of while loop if we're done with the file
}
}
xml_parser_free($xml_parser);
