Looking for an item in the php XML file

Question

I have an xml file, and I would like to bring to the page only one item of that file, in case I can bring all the items of a view only through the code

<?php
    $feed = file_get_contents('https://brasil.elpais.com/rss/brasil/portada_completo.xml');
    $rss = new SimpleXmlElement($feed);

     //echo "<pre>"; print_r($rss);
    foreach($rss->channel->item as $noticia) {
        echo '<p><a href="'.$noticia->link.'" title="'. $noticia->title .'">'.$noticia->title.''.$noticia->description.'</a></p>';
    }       

?> 

In case I don’t want to present all the items, I just want a specific part of XML, which is in the middle of the generated array, the print of the generated array is this:

in case I want to bring the [item][6] array, only I am not able to do this location, and I would also like to ask some way to integrate xmls, in case I have more than 1 I would like to insert the selected tags on the page. If you can help me I’m grateful.

In case show the first item tag of the first xml file, then show the first item tag of the second xml file, dps show the fourth item tag of the first xml file and so on.

Simply do this (remember the Dice starts counting from scratch, then 0 is the first item, 1 is the second, etc):

$rss->channel->item[6];

Example to catch the title:

<?php
$feed = file_get_contents('https://brasil.elpais.com/rss/brasil/portada_completo.xml');
$rss = new SimpleXmlElement($feed);

$item_especifico = $rss->channel->item[6];

echo 'Titulo:', $item_especifico->title;

Note that to catch @attributes Simplexml must use the method ->attributes(), thus:

<?php
$feed = file_get_contents('https://brasil.elpais.com/rss/brasil/portada_completo.xml');
$rss = new SimpleXmlElement($feed);

$item_especifico = $rss->channel->item[6];
$enclosure = $item_especifico->enclosure->attributes();

echo 'Titulo:', $item_especifico->title, '<br>';
echo 'Imagem:', $enclosure->url, '<br>';
echo 'Peso da imagem:', $enclosure->length, '<br>';
