[SOLVED] simplexml_load_string

[SchweppesAle]

hi, I'm trying to parse an xml string in the following format

 

$response = "
<system>
  <status>success</status>
  <resultlist>
    <resultlist id='1'>
      <result id='{field_name}'>{field_value}</result>
      ...
    </resultlist>
    <resultlist id='2'>
      <result id='{field_name}'>{field_value}</result>
      ...
    </resultlist>
    ...
  </resultlist>
</system>";

 

I've tried running

$xml[] = simplexml_load_string($response); //each resulting xml

 

foreach($xml as $entry)
	{
		$result[] = $entry->resultlist->result[4];
	}

 

The result array returns NULL.

You are missing the xml document definition:

 

<?xml version='1.0'?>

I don't think they include that within the return string.

The function returns an object. Why store in an array?

$xml = simplexml_load_string($response);
// debug object
/*
print "<pre>";
print_r($xml);
print "</pre>";
exit();
*/
foreach($xml->system as $child) {

}

ok,  I'm no longer storing it within an array since it wasn't necessary.

 

retrieves the return xml string

public function list_users($config)
{
$login = $config->get_username();
$password = $config->get_password();
$listid = $config->get_listid();

$request = "<system>".
  "<action>getsubscribers</action>".
  "<authorization>".
    "<username>".$login."</username>".
    "<password>".$password."</password>".
  "</authorization>".
  "<parameterlist>".
"<parameter id='List ID'><value>".$listid."</value></parameter>".
"<parameter id='Search Relation'><value>and</value></parameter>".
    "<parameterarr>".
    "</parameterarr>".
  "</parameterlist>".
"</system>";


return $this->_xml = $request;
}

public function query($entry)
{
		// Configuration
		$user_agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";
		$url = "http://server1.streamsend.com/streamsend/api.php";

		// Build Parameters
		$params['xmldata'] = $entry;

		// Open Connection Handle
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
		curl_setopt($ch, CURLOPT_HEADER, 0);
		curl_setopt($ch, CURLOPT_POST,1);
		curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
		curl_setopt($ch, CURLOPT_URL,$url);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

		curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
		// Send Request
		$response = curl_exec ($ch);

		// Close Connection Handle
		curl_close ($ch);

		$xml = simplexml_load_string($response);





	return $this->_result = $xml;
}

 

bit of code which should be parsing the xml string

//$list == the resulting xml from the above code

foreach($list->resultlist as $item)
{
echo '<pre>';
echo var_dump($item);
echo '</pre>';

}

This returns every user who met the search criteria

How would I reference each one of them uniquely though? 

 

You'll see from reading the streamsend API documentation that the string will return a number of <result> tags; each one made unique by an "id" property value. 

 

foreach($list->resultlist->result as $item) still returns a blank page.  Maybe I need to reference each of the result tags based on property value?

doh...alright nevermind.  This solved the problem

 

foreach($list->resultlist->resultlist->result as $item)
{
//do something
}
