[RESOLVED] XML Parsing into variables

[PartialReptile]

Hey,

Is there a way I can query multiple tags in a RSS feed with xpath and return them as a variable to loop. That&#8217;s not very well explained, so; this is the code I&#8217;m using to query the title of each <item> in an RSS feed:

$dom = new DomDocument();
$dom -> load( "news.xml" );

$xp = new DomXPath( $dom );

echo( "news items are<br />" );
$title = $xp -> query( "/rss/channel/item/title" );
foreach( $title as $node )
{
echo( "<h1>". $node -> textContent . "</h1>" );
}

The Structure of the RSS feed is:

<item>
<title>First Title</title>
<link>a link</link>
<description>a description</description>
</item>

What I would like to do for the result of the foreach statement would be something like this:

echo( "<h1>". $title . "</h1>" );
echo( "<p>". $description  . "<br />" );
echo( $link . "</p>" );

Basically, what I want to do is load the text content of each of the child elements in <item> into separate specific variables so that I have full control over them, so I can use them however I wish, like:

(assuming the text content between <link> and </link> was loaded into $link, etc.)

echo ( 'a href=&#8220;' . $link . '&#8221;>' . $title .'</a><br />');
echo ( $description ); 

Or

echo( "<h1>". $title . "</h1>" );
echo( "<p>". $description  . "<br />" );
echo( $link . "</p>" );

And then loop the above for every instance that the parent <item> is found in the xml / rss.

Any help would be greatly appreciated. Even if anyone has a link to a tutorial that might deal with the above, I don&#8217;t mind doing some leg work. Just can&#8217;t seem to find anything that deals with what I&#8217;m looking for.

Cheers.

If you're using php5 you could use SimpleXML:

<?php

$xml = simplexml_load_file('news.xml');

foreach($xml->item as $item)
{
    echo '<h1>' . $item->title . '</h1>';
    echo '<p>' . $item->description . '<br />';
    echo '<a href="' . $item->link . '">More ...</a></p>';
}

Something as simple as that in php5 would suffice 😉

I, emm, ehh, Knew that. I was, ehh, just testing. :o

Thank You, Very Much.

One more question, if you don't mind;

instead of the foreach statement, is there a way I can loop this a specific number of times, as example if I just wanted to loop for the first 4 <items> and then ignore the remainder of the xml file?

<?php

$xml = simplexml_load_file('news.xml');

for($i = 0; $i<=3; $i++)
{
    echo '<h1>' . $xml->item[$i]->title . '</h1>';
    echo '<p>' . $xml->item[$i]->description . '<br />';
    echo '<a href="' . $xml->item[$i]->link . '">More ...</a></p>';
} 
?>
