Question

For example:

def list = {
    books = Book.findAll(...)
    render(contentType: 'text/xml') {
        books(count: books.size()) {
            for(book in books) {
                book(id: book.id) {
                    title(book.title)
                }
            }
        }
    }
}

Using books and book as nodes cause naming conflicts. I understand I can rename everything to prevent the issue but is there a way to escape the nodes to prevent the issue and keep a clean naming convention?

Answer 1

Quote the conflicting node-generating terms:

 'books'(count: books.size()) {

or use a different local variable name.
