Is there any more elegant way to escape SimpleXML attributes to an array?
$result = $xml->xpath( $xpath );
$element = $result[ 0 ];
$attributes = (array) $element->attributes();
$attributes = $attributes[ '@attributes' ];
I don't really want to have to loop through it just to extract the key/value pair. All I need is to get it into an array and then pass it on. I would have thought attributes()
would have done it by default, or at least given the option. But I couldn't even find the above solution anywhere, I had to figure that out on my own. Am I over complicating this or something?
Edit:
I'm still using the above script until I know for sure whether accessing the @attributes array is safe or not.
a more elegant way; it gives you the same results without using $attributes[ '@attributes' ] :
$attributes = current($element->attributes());
Don't directly read the '@attributes'
property, that's for internal use. Anyway, attributes()
can already be used as an array without needing to "convert" to a real array.
For example:
<?php
$xml = '<xml><test><a a="b" r="x" q="v" /></test><b/></xml>';
$x = new SimpleXMLElement($xml);
$attr = $x->test[0]->a[0]->attributes();
echo $attr['a']; // "b"
If you want it to be a "true" array, you're gonna have to loop:
$attrArray = array();
$attr = $x->test[0]->a[0]->attributes();
foreach($attr as $key=>$val){
$attrArray[(string)$key] = (string)$val;
}
You could convert the whole xml document into an array:
$array = json_decode(json_encode((array) simplexml_load_string("<response>{$xml}</response>")), true);

For me below method worked
function xmlToArray(SimpleXMLElement $xml)
{
$parser = function (SimpleXMLElement $xml, array $collection = []) use (&$parser) {
$nodes = $xml->children();
$attributes = $xml->attributes();
if (0 !== count($attributes)) {
foreach ($attributes as $attrName => $attrValue) {
$collection['@attributes'][$attrName] = strval($attrValue);
}
}
if (0 === $nodes->count()) {
if($xml->attributes())
{
$collection['value'] = strval($xml);
}
else
{
$collection = strval($xml);
}
return $collection;
}
foreach ($nodes as $nodeName => $nodeValue) {
if (count($nodeValue->xpath('../' . $nodeName)) < 2) {
$collection[$nodeName] = $parser($nodeValue);
continue;
}
$collection[$nodeName][] = $parser($nodeValue);
}
return $collection;
};
return [
$xml->getName() => $parser($xml)
];
}
This also provides me all the attributes as well, which I didn't get from any other method.
