I've put together an incredibly basic module with only the functionality needed for what you have asked in this question.

I have added the view change (that snippet) into an xml file in a subdirectory called 'views' to organise it properly. Fundamentally you just need an __init__.py file, an __openerp__.py file with your dependencies (in this case website_sale, etc.), and your view definition (in this case /views/B2B_Add_To_Cart.xml).

Inside this XML file you just need to place your <template> tags nested inside the opening and closing <openerp> and <data> tags. Remember that you are working with XHTML/XML, and therefore opening and closing tags must be properly nested or you will run into problems.

In regards to the t-if statements, you are simply stating in Qweb that it should use this tag only if the user id in the database in the database (not user_id.partner_id.name)  is equal to (==) the name 'Public user'.

Therefore whatever nested tags are inside that <a> tag there, they will only be displayed to users if there user id is not 'Public user'.
