Hey all I got this script:

 

$x = new SimpleXmlElement($content);

 

foreach($x->channel->item as $entry) { 

    echo "<a href='$entry->link' title='$entry->title'>" . $entry->title . "</a>"; 

} 

 

This should take an rss xml feed and save the title with a link to the original post as $entry. The problem is that instead of the foreach() function I need a function or a different way to do this that will just take the first item on the list.

 

Please help this is driving me nuts.

<?php
$x = new SimpleXmlElement($content);
$children = $x->children();
$entry = $children[0]; // Child[0] is the first element.
echo "<a href='$entry->link' title='$entry->title'>" . $entry->title . "</a>";  
?>

ok that worked kind of, when i run the script it displays the title of the rss feed. this is the first title xml tag. So I guess what I need is to get the second child, i guess. Is this possible?

[systomic26]

so I guess it can't be done then?

If you mean the second child, then use:

<?php
$x = new SimpleXmlElement($content);
$children = $x->children();
$entry = $children[1]; // Child[1] is the second element.
echo "<a href='$entry->link' title='$entry->title'>" . $entry->title . "</a>";  
?>

 

 

If you mean the first sub-child of the first node, then use:

<?php
$x = new SimpleXmlElement($content);
$level1 = $x->children();
$level2 = $level1->children();
$entry = $level2[0];
echo "<a href='$entry->link' title='$entry->title'>" . $entry->title . "</a>";  
?>
