PHP: read a php url as xml and parse it - php

Question

i got a url like this one http://somedomain.com/frieventexport.php and the content of this url is a plain XML structure if I check out the source-code of the site:
How can I parse this URL and use it in PHP?
This script gives me an error… "Error loading XML".
<?php
$xml_url = "http://somedomain.com/frieventexport.php";
if (($response_xml_data = file_get_contents($xml_url))===false){
echo "Error fetching XML\n";
} else {
libxml_use_internal_errors(true);
$data = simplexml_load_string($response_xml_data);
if (!$data) {
echo "Error loading XML\n";
foreach(libxml_get_errors() as $error) {
echo "\t", $error->message;
}
} else {
print_r($data);
}
}
?>

One of the best options in my opinion is to use CURL to get the raw XML data from the url:
$curl = curl_init();
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $curl, CURLOPT_URL, "http://somedomain.com/frieventexport.php" );
$xml = curl_exec( $curl );
curl_close( $curl );
You can then use DOMDocument to parse the xml:
$document = new DOMDocument;
$document->loadXML( $xml );
I would also recommend using <![CDATA[]> tags in your XML. Please read the following:
What does <![CDATA[]]> in XML mean?

file_get_contents() is usually disabled if this is shared hosting, if not you can set allow_url_fopen in php.ini (however beware of the security risks). You can check the setting of this using php_info() or var_dump(ini_get('allow_url_fopen')) to show if it's allowed or not.
If you cannot do the above, you can use CURL to fetch external content

Try the following:
$url = 'xml-file.xml';
$xml = simplexml_load_file($url);
print_r($xml);

Answer 4

Try this :
$livescore_data = new SimpleXMLElement($file);
