PHP How to link Soap XML with XML Schema(.xsd) - php

Question

I have two urls.
http://www.labs.skanetrafiken.se/v2.2/GetStartEndPoint.xsd
http://www.labs.skanetrafiken.se/v2.2/querypage.asp?inpPointFr=lund&inpPointTo=ystad
How do I get these two to collaborate so I can extract the information via PHP?
How does one extract all the information out of the XML file into a PHP object or array.

Answer 1

I just answered my own question with this code:
/**
* convert xml string to php array - useful to get a serializable value
*
* #param string $xmlstr
* #return array
* #author Adrien aka Gaarf
*/
function xmlstr_to_array($xmlstr) {
$doc = new DOMDocument();
$doc->loadXML($xmlstr);
return domnode_to_array($doc->documentElement);
}
function domnode_to_array($node) {
$output = array();
switch ($node->nodeType) {
case XML_CDATA_SECTION_NODE:
case XML_TEXT_NODE:
$output = trim($node->textContent);
break;
case XML_ELEMENT_NODE:
for ($i=0, $m=$node->childNodes->length; $i<$m; $i++) {
$child = $node->childNodes->item($i);
$v = domnode_to_array($child);
if(isset($child->tagName)) {
$t = $child->tagName;
if(!isset($output[$t])) {
$output[$t] = array();
}
$output[$t][] = $v;
}
elseif($v) {
$output = (string) $v;
}
}
if(is_array($output)) {
if($node->attributes->length) {
$a = array();
foreach($node->attributes as $attrName => $attrNode) {
$a[$attrName] = (string) $attrNode->value;
}
$output['#attributes'] = $a;
}
foreach ($output as $t => $v) {
if(is_array($v) && count($v)==1 && $t!='#attributes') {
$output[$t] = $v[0];
}
}
}
break;
}
return $output;
}
$xml = 'http://www.labs.skanetrafiken.se/v2.2/querypage.asp?inpPointFr=lund&inpPointTo=ystad';
$xmlstr = new SimpleXMLElement($xml, null, true);
$array = xmlstr_to_array($xmlstr->asXML());
print_r($array);
This returns an array with the XML, exactly what I want to be able to work with.
