Answer 1

If anyone is targeting yahoo rss feed may benefit from this snippet

<?php
    $rssUrl="http://news.yahoo.com/rss/topstories";
    //====================================================
    $xml=simplexml_load_file($rssUrl) or die("Error: Cannot create object");
    //====================================================
    $featureRss =  array_slice(json_decode(json_encode((array) $xml ),  true ), 0 );
 /*Just to see what is in it 
use this function PrettyPrintArray() 
instead of var_dump($featureRss);*/

    function PrettyPrintArray($rssData, $level) {
    foreach($rssData as $key => $Items) {
    for($i = 0; $i < $level; $i++)
    echo("&nbsp;");
    /*if content more than one*/
    if(!is_array($Items)){
    //$Items=htmlentities($Items); 
    $Items=htmlspecialchars($Items);
    echo("Item " .$key . " => " . $Items . "<br/><br/>");
    }
    else 
    {
    echo($key . " => <br/><br/>");
    PrettyPrintArray($Items, $level+1);
    }
    }
    }
    PrettyPrintArray($featureRss, 0);
?>

You may want to run it in your browser first to see what is there and before looping and style it up pretty simple

To grab the first item description

<?php
    echo($featureRss['channel']['item'][0]['description']);
?>

Answer 2

You can use the asXML method

echo $xml->asXML();

You can also give it a filename

$xml->asXML('filename.xml');

Answer 3

This worked for me:

echo(header('content-type: text/xml'));

Answer 4

To display the html/xml "as is" (i.e. all entities and elements), simply escape the characters <, &, and enclose the result with <pre>:

$XML = '<?xml version="1.0" encoding="UTF-8"?>
<root>
    <foo>ó</foo>
    <bar>&#xF3;</bar>
</root>';

$XML = str_replace('&', '&amp;', $XML);
$XML = str_replace('<', '&lt;', $XML);
echo '<pre>' . $XML . '</pre>';

Prints:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <foo>ó</foo>
    <bar>&#xF3;</bar>
</root>
