I feel pretty stupid posting this but I just can't sort it. I have a very short and simple piece of XML and I can't parse it, I have parsed xml in the past without issue but this I just can't sort for some reason.
The XML:
<?xml version="1.0" encoding="UTF-8"?>
<RegionalFcst xmlns="www.metoffice.gov.uk/xml/metoRegionalFcst"
issuedAt="2014-01-18T04:00:00"></RegionalFcst>
A print_r of the simplexml object it is loaded into:
(
[@attributes] => Array
(
[issuedAt] => 2014-01-18T04:00:00
)
)
All I want is that"issuedAt" time stamp, but it's an attribute not an element. I have tried a foreach through @attributes and got nothing. I am even thinking of streaming it through an awk script (hosted on linux). I really would like to avoid that and stay within PHP.
Any help appreciated.
Rob

The manual is not very clear on this. I think the problem you are
having is that everything you access is returned as a SimpleXMLElement
object and you want a PHP string.

print_r((string)$xml['issuedAt']);

Rob,
You're close, your simplexml object is but it is an object, not an
array. You have to call the attributes() function to get the array
of attributes, i.e.
foreach ($xml->attributes() as $name => $value)
echo $name . '="' . $value ."\"\n";
You can access just the 'issuedAt' attribute with
$name = 'issuedAt';
$value = $xml->attributes()->$name;
(Note: when using a non-default namespace you will have to specify the
namespace you're using, i.e.
$xml->RegionalFcst[0]->attributes....
Don't try to just cast the object as a string; you will get all kinds of
extra stuff if other attributes are added to your xml object.

Thanks for the help, it's simple once you know how, isn't that always the case. Anyway I now have what I need and can dump my external call to awk.
Thank you both for the tips and help.
