php -- rss tutorial

[hyster]

i followed the guide on this site for the rss tutorial.

i altered it to what i wanted but i can not get it to loop. it will only display the first line.

the tutorial says to use echo <<<EOF but they caused the script to not work.

 

any help would be gratefull.

 

<?php
$xml = new SimpleXMLElement('http://api.wot-blackdeath.ru/wot-news/eu/wot-news.xml', null, true);

echo "<table border='1'>" ;	  

foreach($xml as $data){
// loop through our xml	   
?>			   
<tr><td> <?php echo $data->title ?></td></tr>			  
<tr><td> <?php echo $data->description ?></td></tr>			  
<tr><td> <?php echo $data->link ?></td></tr>		  
<tr><td> <?php echo $data->pubDate ?></td></tr>					 
<?php
}
echo "</table>";
?>

foreach($xml as $data){

foreach what part of the $xml?

The xml looks like it could contain any number of <channel> entries. Each of these channels has its own title, description etc. as well as any number of <item> entries which also have their own title, description etc.

 

So, going by the code you have so far, it might read better as:

 

<?php foreach ($xml as $channel) : ?>

 

Then you could access the CHANNEL info like this:

 

<?php echo $channel->title; ?>
<?php echo $channel->description; ?>
etc...

 

You could then cycle through each $channel's <item> entries:

 

<?php foreach ($channel->item as $item) : ?>

 

After which you could access the ITEM info like this:

 

<?php echo $item->title; ?>
<?php echo $item->description; ?>
etc...

 

Hope that clears things up a little.

i carnt get my head round this lol.

 

the xml im reading is laid out like this

 

<channel>
 <item>
	 <title>data</title>
	 <description>data</description>
	 <link>data</link>
	 <pubDate>data</pubDate>
	 <guid>data</guid>
 </item>


 <item>
	 <title>data</title>
	 <description>data</description>
	 <link>data</link>
	 <pubDate>data</pubDate>
	 <guid>data</guid>
</item>
<channel>

 

using following code i get the php to loop the correct amount of times ( but the echo'd value is "item"

<?php
$xml = new SimpleXMLElement('http://api.wot-blackdeath.ru/wot-news/eu/wot-news.xml', null, true);
echo "<table border='1'>" ;	
foreach($xml->channel->item as $data => $value){

?>			
<tr><td>1</td><td><b> <?php echo $data ?></b></td></tr>			
<tr><td>2</td><td> <?php echo $data ?></td></tr>			
<tr><td>3</td><td> <?php echo $data ?></td></tr>		
<tr><td>4</td><td> <?php echo $data ?></td></tr>					
<tr><td>5</td><td> <?php echo $data ?></td></tr>
<?php
}
echo "</table>";
?>

Well... yeah. That's the key of the "array" you're looping over. The name of the node. You don't want the name.

foreach ($xml->channel->item as $item) {
   echo '<p>' . $item->description . '</p>';
   // etc
}
