I am using an XML feed which unfortunately uses the @ symbol within some of the definitions. Here is an example,

Code:

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [Name] => Cirrus Blue Demo
            [Status] => 0
            [Latitude] => 0.0
            [Longitude] => 0.0
            [Units] => Metric
        )

    [Sensor] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [Name] => Internal Temperature Sensor
                            [Port] => 1
                            [Status] => 0
                        )


Theoretically I should be able to print the name of the sensor using,

Code:
{$xmlMod->Sensor[0]->@attributes->Name}


However, it does not work because the @ symbol breaks the Smarty Compiler.

Syntax Error in template "module_db_tpl:XMLMadeSimple;sensorsLive" on line 11 "{$xmlMod->Sensor[0]->Condition->@attributes->Type}" - Unexpected "@", expected one of: "{" , "$" , "identifier"

Does anyone know how to resolve this?

Thanks

try this:

{assign var=attr value="{@attributes}"}
{$xmlMod->Sensor[0]->$attr->Name}

I'm not sure if Smarty 3 supports in-line syntax, you might also try:

{$xmlMod->Sensor[0]->{@attributes}->Name}

It must be

Code:
{assign var=attr value="@attributes"}
{$xmlMod->Sensor[0]->$attr->Name}


There is no working inline syntax:

Thanks for your suggestions. I have tried all sorts of combinations and nothing seems to work, any other ideas of an approach I could try?

ay be it should be

Code:
{assign var=attr value="@attributes"}
{$xmlMod->Sensor[0]->$attr['Name']}


as 'Name' is an array index and not an object property
