Fatal error: Call to a member function attributes() on a non...

Hi. I'm using your script on a server where php5 is not available...which by the way is probably going to save me on my project...so thank you!!
But I'm having problems that I don't have when using the SimpleXMLElement functionality in php5.
I'll show you where the script has problems and returns a fatal error. On the following xml data, it does fine.

[2] => SimpleXMLObject Object
(
[receipt_time] => 2009-02-21T13:46:29Z
[observation_time] => 2009-02-21T13:36:00Z
[aircraft_ref] => C182
[latitude] => 41.7833
[longitude] => -107.2
[altitude_ft_msl] => 9000
[turbulence_condition] => SimpleXMLObject Object
(
[@attributes] => SimpleXMLObject Object
(
[turbulence_intensity] => LGT
[turbulence_base_ft_msl] => 8000
)

)

[pirep_type] => PIREP
[raw_text] => RWL UA /OV RWL /TM 1336 /FL090 /TP C182 /TB LGT 080 /RM PATCHY MTN OBSC SE SMOOTH AT 090
)

But when there are two elements in [turbulence_condition], my script returns the following error: Fatal error: Call to a member function attributes() on a non-object in C:\perl-scripts\west_pirep_xml_php4.php on line 53.

Here's the xml that its hanging up on...note that [turbulence_condition] is now an array and I think that is what's causing problems:
[3] => SimpleXMLObject Object
(
[receipt_time] => 2009-02-21T13:40:10Z
[observation_time] => 2009-02-21T13:34:00Z
[quality_control_flags] => SimpleXMLObject Object
(
[no_flt_lvl] => TRUE
)

[aircraft_ref] => DC6
[latitude] => 61.1742
[longitude] => -149.996
[altitude_ft_msl] => 3000
[sky_condition] => SimpleXMLObject Object
(
[@attributes] => SimpleXMLObject Object
(
[sky_cover] => SKC
[cloud_base_ft_msl] => 3000
[cloud_top_ft_msl] => 60000
)

)

[turbulence_condition] => Array
(
[0] => SimpleXMLObject Object
(
[@attributes] => SimpleXMLObject Object
(
[turbulence_intensity] => LGT
[turbulence_base_ft_msl] => 0
[turbulence_top_ft_msl] => 6000
)

)

[1] => SimpleXMLObject Object
(
[@attributes] => SimpleXMLObject Object
(
[turbulence_intensity] => NEG
)

)

)

[icing_condition] => SimpleXMLObject Object
(
[@attributes] => SimpleXMLObject Object
(
[icing_intensity] => NEGclr
[icing_base_ft_msl] => 3000
[icing_top_ft_msl] => 60000
)

)

[visibility_statute_mi] => 10
[pirep_type] => PIREP
[raw_text] => ANC UA /OV ANC /TM 1334 /FLUNKN /TP DC6 /SK SKC /WX FV10SM /TB LGT SFC-060/SMOOTH O70 /RM DURGC W BND
)

Do you have suggestions on how I can handle this type of situation, and prevent the script from stopping when encountering this array? Thanks for your time,

Here's my script if it helps...

try using

$var = $xml->item->attributes();
$var2 = $var->item2;

instead of

$var2 = $xml->item->attributes()->item2;

this will solve your problem.
