Hello.

I am currently trying to avoid the output of an XML Block element alltogether if it is empty.

I tried:

{if ne( $node.data_map.positions,'' )}
    {attribute_view_gui attribute=$node.data_map_positions}
{/if}

as well as

{if ne( $node.data_map.positions.output.output_text,'' )}
    {attribute_view_gui attribute=$node.data_map_positions}
{/if}

But to no success.

Anyone?

Best,
Marcus

Hello,

Try this one:

{if eq( $node.data_map.positions.has_content, 1)}
    {attribute_view_gui attribute=$node.data_map_positions}
{/if}

$node.data_map.positions.has_content is a boolean.

That works.

Thank you!

Hi,

Just a little tip: It will work without eq operator:

{if $node.data_map.positions.has_content}
   {attribute_view_gui attribute=$node.data_map_positions}
{/if}
