[Metafacture] Metamorph: compare two values

[Prongué Nicolas (HES)]

Dear list,

I am working on the transformation of swiss bibliographic data with the Metamorph language (Swissbib project). Here is my question:

Is it possible to compare 2 values in the source fields (in this case MARC/XML-subfields) and then to apply a rule only if these values are equal (or not) ?
Example: I have a language code in field 008, I have another language code in field 041. I would like to use both of them only if they are not the same…

Do you have an idea of how to do that?

Thanks for your help

Nicolas Prongué
