XSL select where element has two attributes

Question

How do I select elements that have two attributes?

I can do

@name | @area

which is "name or area", but how do I do "name and area"?

Answer 1

Well, don't use @name | @area - it's not 'or', it's a join which happens to work incidentally.

For 'or', do foo[@name or @area]. For 'and', do foo[@name and @area].

Answer 2

XPath does provide you with an and operator which can be used to evaluate multiple conditions using predicates:

Possibles:

//MyElement[@name][@area]
//MyElement[@name and @area]
