How to Extract and Parse XML Responses with PHP cURL?

Extracting XML Responses with PHP cURL

When using PHP's cURL method to retrieve responses from servers, you may encounter situations where the response is in XML format. However, by default, cURL stores the output in a scalar type variable, making it challenging to parse efficiently.

To address this issue, here's a method to convert the XML response into an object, hash, or array for easier parsing:

<code class="php"><?php
function download_page($path) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $path);
    curl_setopt($ch, CURLOPT_FAILONERROR, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 15);
    $retValue = curl_exec($ch);
    curl_close($ch);
    return $retValue;
}

$sXML = download_page('http://alanstorm.com/atom');
$oXML = new SimpleXMLElement($sXML);

foreach ($oXML->entry as $oEntry) {
    echo $oEntry->title . "\n";
}</code>

In this example, we:

1. Use the download_page() function to retrieve the XML response as a string ($sXML).
2. Create a SimpleXMLElement object ($oXML) from the XML string.
3. Loop through the XML elements and access their properties, such as title.
