Remove empty tag from XML

Hi!

Im trying to remove tag from XML file if data is empty using your code as example:

function my_output_param_color( $value ) {
	$xml = '';
	if ( ! empty( $value ) ) {
		$xml .= '**LT**ProductColor**GT**' . $value . '**LT**/ProductColor**GT**';
	}
	return $xml;
}

Example usage in the XML template:
[my_output_param_color({Product Color})]

Everything is working fine, if i only use one function, than tag, one function, than tag ..

Example:

[my_output_param_color({Product Color})]
<Title>{Title}</Title>
[my_output_param_bluetooth({Product BLUETOOTH})]
<ShortDescription>{Short Description}</ShortDescription>

but im getting an “An unknown error occurred” if i try to use one function after another

Example:

[my_output_param_color({Product Color})]
[my_output_param_bluetooth({Product BLUETOOTH})]

CDATA is turned off.

Thank you for your help!
