The text that you are receiving is nothing more than XML return. To work with PHP , you should parse with simplexml_load_string :

<?php

$xml = <<<XML
<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>  
<checkout>  
    <currency>BRL</currency>  
    <items>  
        <item>  
            <id>0001</id>  
            <description>Notebook Prata</description>  
            <amount>24300.00</amount>  
            <quantity>1</quantity>  
            <weight>1000</weight>  
        </item>  
        <item>  
            <id>0002</id>  
            <description>Notebook Rosa</description>  
            <amount>25600.00</amount>  
            <quantity>2</quantity>  
            <weight>750</weight>  
        </item>  
    </items>  
    <reference>REF1234</reference>  
    <sender>  
        <name>José Comprador</name>  
        <email>[email protected]</email>

            <areacode>11</areacode>

    </sender>  
    <shipping>  
        <type>1</type>  
        <address>  
            <street>Av. Brig. Faria Lima</street>

XML;

$xmlObject = simplexml_load_string($xml);

var_dump($xmlObject);

Will return:
