creating arrays in xslt

Question

can array\'s be created and used in xslt? If so are there suitable examples online to study? If not is there a way to store values in a way that mimics an array?

Answer 1

With XSLT 2.0 you can model any data type you want to.

As example:

    
    
        A
        B
        C
    
    
        
    

With any input, output:

B

In XSLT 1.0 there is not Temporaly Result Tree data type. There is a Result Tree Fragment data type that does not allow node-set operator. So, the only way to go is with extensions functions: in this case node-set() from EXSLT (MSXSL has a built-in node-set() extension, also).

So, in XSLT 1.0 without extensions you can have only inline data model, or by params or by external document. As example:

    
    
        A
        B
        C
    
    
    
        
    

Result, with any input:

B

Only if you want to, I can provide you a XSLT 1.0 plus extensions example (It's not standar...)
