Re: SimpleXML returning Object names with hyphens

Hey all, I've run into a snag trying to use some XML output from NOAA.

what NOAA when its at home?

The problem is that some of the fields it sends to me have a hyphen in the name. Simple XML then creates objects with hyphens in their name. So here's the object I am having issues with: object(SimpleXMLElement)#7 (2) { wind-speed => object(SimpleXMLElement)#9 (2) {

    name => string(10) Wind Speed
    value => array(37) {
      0 => string(1) 4
      1 => string(1) 4

...

      33 => string(3) 328
      34 => string(3) 338
      35 => string(3) 350
      36 => string(3) 350

you could have trimmed that down a bit.

    }

} } And here's my code issues: $xmlobj->data->parameters->direction access works fine. $xmlobj->data->parameters->direction->value works fine. Gives me the array.

first turn up error reporting to full error_reporting( E_ALL | E_STRICT );

$xmlobj->data->parameters->wind-speed returns an int value of 0. $xmlobj->data->parameters->wind-speed->value gives me an error:

then try something like (I'm guessing this might work, then again the behaviour of simpleXML [especially auto/magic casting] is greek to me): $xmlobj->data->parameters->{'wind-speed'} $xmlobj->data->parameters->{'wind-speed'}->value

Parse error: parse error, unexpected T_OBJECT_OPERATOR in noaa.php on line 59 So, what am I doing wrong? The only thing I can think of is the - in the wind-speed object name. Any help would be appreciated! -Charlie
