How to display only the second item from XML with this PHP script?

<xml>

        <name>Examplename</name>
        <amount>0000</amount>
    </item>
    <item>

<?

// DOMElement->getElementsByTagName() -- Gets elements by tagname
// nodeValue : The value of this node, depending on its type.
// Load XML File. You can use loadXML if you wish to load XML data from a string

$objDOM = new DOMDocument();
$objDOM->load("feed.xml"); //make sure path is correct


$note = $objDOM->getElementsByTagName("item");

// for each note tag, parse the document and get values for

You need to exploit XPath

Using SimpleXML:

<?php
$str = <<<STR
<?xml version="1.0" encoding="utf-8"?>
<XmlDoc>
    <item>
        text
    </item>
    <item>
        text2
    </item>
</XmlDoc>
STR;
$xml = simplexml_load_string($str);
$second_item = $xml->xpath('//item[2]'); // notice [2]!
var_export($second_item);

Using DOMDocument and DOMXPath:

<?php
$str = <<<STR
<?xml version="1.0" encoding="utf-8"?>
<xml>
    <item>
        <name>Examplename</name>
        <amount>0000</amount>
    </item>
    <item>
        <name>Examplename</name>
        <amount>0000</amount>
    </item>
    <item>
        <name>Examplename</name>
        <amount >0000</amount>
    </item>
    <item>
        <name>DExamplename</name>
        <amount>0000</amount>
    </item>
</xml>
STR;

$xml = DOMDocument::loadXML($str);

$xpath = new DOMXpath($xml);
$x = $xpath->query('//item[2]');
var_export($x->item(0)->nodeValue);
