SimpleXML tags with – in the name

Posted on by

Sometimes a xml file will have tags with “-“s in the name.
It is not to hard to parse this using simplexml, just use the tagname inside curly brackets like: “{tag-name}”

<?xml version="1.0" encoding="utf-8"?>
<medprod xmlns:npl="urn:schemas-instance" version="129">
  <statuses>
    <mpa_status xmlns:mpa="urn:schemas-mpa" datastatus="valid" procstatus="reviewed"/>
  </statuses>
  <mpa_pharmaceutical-form-group-lx xmlns:mpa="urn:schemas-mpa" v="OSD"/>
</medprod>

Let’s assume we load the above in a SimpleXML object called $simplemedprodXml

$simplemedprodXml= simplexml_load_string($xmlString);
echo (string)$simplemedprodXml['version'];
echo (string)$simplemedprodXml->statuses->mpa_status['datastatus'];
echo (string)$simplemedprodXml->statuses->mpa_status['procstatus'];
echo (string)$simplemedprodXml->{'mpa_pharmaceutical-form-group-lx'}['v'];

PHP: casting stdClass Object to a array

Posted on by

When using Soapclient to access a webservice the returned object will be of a stdClass Object.

If you don’t wish to access this as an object, but would find it easier to use it as an array then a quick cast solves this.

/*As an object*/
print_r($soapResult->contents);
/*cast to an array*/
$soapResult = (array)$soapResult;
print_r($soapResult['contents']);

PHP5: Quick on exceptions

Very quick (&dirty):

try{
	doStuff();
}
catch (Exception $e){
	echo 'Error on line '. $e->getLine().' in '. $e->getFile() . $e->getMessage();
	//Or if you are working inside an object, you could use.
	echo 'Error on line '.$this->getLine().' in '.$this->getFile() . $e->getMessage();
}

Now to catch a specific kind of exception (in this case CustomException), and say woups, but to re-throw all other Exceptions.

try{
	doStuffThatCanGiveCustomException();
}
catch (Exception $e){
	//echo get_class($e) . "<br/>";
	if (get_class($e) == "CustomException" && $e->getMessage() === "My custom exception message."){
		echo "woups";
	}
	else
		throw $e;
}

To throw a custom exception:

 throw new Exception('My exception message');
