Proton is a simple, "code-less" engine for xml/xhtml templates. Code-less, because it uses 3 types of ID (attribute) in a template file, rather than snippets of code — this moves the complexity out of the template and into the application.

A simple Proton template looks like this:

    

        

            PAGE TITLE

        

        

            
PAGE TITLE


            
LINK ITEM


            


                
LIST ITEMS

            

        

    


And to render this template in Python, you might do something like this:

    from proton import template

    tmp = template.get_template('test.xhtml')

    tmp.set_value('title', 'An Xhtml Page', '*')

    tmp.set_value('link', 'This is a link to Google')

    tmp.set_attribute('link', 'href', 'http://www.google.com')

    tmp.repeat('list-item', 5)

    for x in range(0, 5):

        tmp.set_value('list-item', 'test%s' % x, x)

    print(str(tmp))

    

Resulting in the following output:

    

        

            An Xhtml Page

        

        

            
An Xhtml Page


            
This is a link to Google


            


                
test0

                
test1

                
test2

                
test3

                
test4

            

        

    


Similarly in Haskell, you could do the following:

    tmps <- loadTemplates "templates"

    tmp <- getTemplate tmps "templates/test.xhtml"

    tmp <- setElementValue tmp "title" "An Xhtml Page" 0

    tmp <- setElementValue tmp "link" "This is a link to Google" 0

    tmp <- setAttributeValue tmp "link" "href" "http://www.google.com" 0

    tmp <- setElementValues tmp "list-item" (map (\x -> "test" ++ (show x)) [0..4])

    

    s <- renderTemplate tmp
