Agustín BonilloSubject: User-Defined Functions
Author: Agustín Bonillo

Hi, I speak english not very well, so I write only my question:

How I can create a User-Defined Function in Stylus Studio?

I try to create it so:

define function get-name($doc) string*

and Stylus Studio says me:

Error: Unrecognized character 'f' (0x66)
in file://c:\get-name-countries.xquery, line 17, column 8.

I have the book: "Addison Wesley - XQuery from the Experts.
A Guide to the W3C XML Query Language" and it explains that
user-defined functions are:

(example in the book)

define function books-by-author($last,$first)
as element()*
for $b in doc("books.xml")/bib/book
where some $ba in $b/author satisfies

The XQuery spec draft has been changed since that book has been printed.
According to the latest draft, you should define your user defined function as:

declare function local:books-by-author($last,$first) as string*

Note the change from "define" to "declare"; and the fact that now user defined functions must have a namespace prefix.

See http://www.w3.org/TR/xquery/ (section 4.12) for more details.

Hope this helps,

Also, you had just 'string' instead of 'as string' as the return type.
