Possibility of concatenation

just a crazy  idea in my car this morning

is it possible ton concatenate string into the xml?

example :

<image image=“Sheet_”&"@@poster" x=“0” y=“107” w=“1133” h=“300”/>

or

  <image image=“Sheet_”+"@@poster" x=“0” y=“107” w=“1133” h=“300”/>

or

 <image image=“Sheet_”||"@@poster" x=“0” y=“107” w=“1133” h=“300”/>

great opportunity to use alternate sheet directly linked with the @@poster

of course difficult to test in my car :wink:

i tried some of these, when i first customised the anodized theme…

It did not work.

Concatenation in xml files can only be done with XSL functions i think.

i wonder if the hub support xsl
