Using XML Parser to get and display RSS Data

Cokemonkey11

I'm not sure what's wrong; hoping it's just my syntax/code.

For some reason this just doesn't work.

Any help would be appreciated.


<?php
	function begEleDevBlog($parseDevBlog,$tagNameDevBlog,$attrsDevBlog){
		global $gInnerItemDevBlog,$gTagDevBlog,$gIndexValDevBlog,$gPostNumDevBlog;
   		if($gInnerItemDevBlog){
			$gTagDevBlog=$tagNameDevBlog;
		}
		elseif($tagNameDevBlog=="ITEM"){
       		$gInnerItemDevBlog=true;
   		}
	}

function characterDataDevBlog($parseDevBlog,$dataDevBlog){
	global $gInnerItemDevBlog,$gTagDevBlog,$titleDevBlog,$descriptionDevBlog,$DevBlogkDevBlog,$gIndexValDevBlog,$gPostNumDevBlog;
	switch($gTagDevBlog){
		case "title":
		$titleDevBlog.=$dataDevBlog;
		break;

		case "description":
		$descriptionDevBlog.=$dataDevBlog;
		break;

		case "link":
		$DevBlogkDevBlog.=$dataDevBlog;
		break;
	}
}

function endElementDevBlog($parseDevBlog,$tagNameDevBlog){
	global $gInnerItemDevBlog,$gTagDevBlog,$titleDevBlog,$descriptionDevBlog,$DevBlogkDevBlog,$gIndexValDevBlog,$gPostNumDevBlog;
	echo("<p><b><a href='".$DevBlogkDevBlog."'>".$titleDevBlog."</a></b></p>");
	echo("<p>".$descriptionDevBlog."</p>");
	$titleDevBlog="";
	$descriptionDevBlog="";
	$DevBlogkDevBlog="";
	$gInnerItemDevBlog=false;
}

$xmlParserDevBlog=xml_parser_create();
xml_set_element_handler($xmlParserDevBlog,"begEleDevBlog","endElementDevBlog");
xml_set_character_data_handler($xmlParserDevBlog,"characterDataDevBlog");

$fpDevBlog=fopen("http://forum.wartidegame.com/syndication.php?fid=48&limit=5","r") or die("Error reading RSS data.");

while($dataDevBlog=fread($fpDevBlog,4096)){
	xml_parse($xmlParserDevBlog,$dataDevBlog,feof($fpDevBlog)) 
		or die(sprintf("XML error: %s at DevBlog %d",
	xml_error_string(xml_get_error_code($xmlParserDevBlog)),  
	xml_get_current_DevBloge_number($xmlParserDevBlog)));
}

fclose($fpDevBlog);
xml_parser_free($xmlParserDevBlog);
echo '<hr /> : $gInnerItemDevBlog', $gInnerItemDevBlog,'<hr /> $gTagDevBlog: ', $gTagDevBlog,'<hr /> $titleDevBlog: ', $titleDevBlog,'<hr /> $descriptionDevBlog: ', $descriptionDevBlog,'<hr /> $DevBlogkDevBlog: ', $DevBlogkDevBlog,'<hr /> $gIndexValDevBlog: ', $gIndexValDevBlog,'<hr /> $gPostNumDevBlog: ', $gPostNumDevBlog;
?>

What you're seeing is the output of this line:

echo '<hr /> : $gInnerItemDevBlog', $gInnerItemDevBlog,'<hr /> $gTagDevBlog: ', $gTagDevBlog,'<hr /> $titleDevBlog: ', $titleDevBlog,'<hr /> $descriptionDevBlog: ', $descriptionDevBlog,'<hr /> $DevBlogkDevBlog: ', $DevBlogkDevBlog,'<hr /> $gIndexValDevBlog: ', $gIndexValDevBlog,'<hr /> $gPostNumDevBlog: ', $gPostNumDevBlog;

Change the single-quotes to double-quotes and that should fix your problem.

sorry, nevermind..... just looked a little closer....

Couldn't use your code, but using SimpleXML, here's a short implementation of what you are trying to do (I think):

$data = file_get_contents('http://forum.wartidegame.com/syndication.php?fid=48&limit=5');
if(!$data)
{
        die('Error reading RSS data.');
}

$xml = simplexml_load_string($data);
if($xml->channel->children())
{
        foreach($xml->channel->children() as $child)
        {
                if($child->getName() == 'item')
                {
                        echo '
                        <p>
                                <strong>
                                        <a href="'.(string) $child->link.'">'.(string) $child->title.'</a>
                                </strong>
                        </p>
                        <p>'.(string) $child->description.'</p>';
                }
        }
}

Worked wonderfully, thank you.

Edit: I thought I understood what it was doing, but when I went to edit it I found I was actually retarded.

Could someone explain why this doesn't work?

<?php
$data2=file_get_contents('http://forum.wartidegame.com/syndication.php?fid=5&limit=5');
if(!$data2){
	die('Error reading RSS data.');
}

$xml2=simplexml_load_string($data2);
if($xml2->channel->children()){
	foreach($xml2->channel->children() as $child2){
		if($child2->getName()=='item'){
			echo '
			<p>
				<a href="'.(string) $child2->link.'">'.(string) $child2->title.'</a>
			</p>';
		}
	}
}
?>

I'm gonna take a stab and say because there are no children named "item" in that feed 😉

	<item>
...

Seems like there is

http://forum.wartidegame.com/syndication.php?fid=5&limit=5

I'm gonna say the url you're entering has a different fid than the url you're using. Fid 5 has no items in it when I browse it.

Or perhaps it has to do with maybe being logged in vs. not logged in (i.e. a hidden board)?
