Text.Hquery

This module exports the top level constructors used for building node transformations. For example, if your template is

 <div class="person">
   <div class="name"></div>
   <div class="occupation"></div>
 </div>

and you invoke hquery like this:

 import Text.Hquery
 template = ... -- parse your template here
 people = [ ("Justin Bieber", "Celebrity")
          , ("Jens Kidman", "Musician")
          ]
 bindPerson (n, o) = hq ".name *" n . hq ".occupation *" o
 f = hq ".person *" $ map bindPerson people
 f template

you'll get markup like this:

 <div class="person">
   <div class="name">Justin Bieber</div>
   <div class="occupation">Celebrity</div>
 </div>
 <div class="person">
   <div class="name">Jens Kidman</div>
   <div class="occupation">Musician</div>
 </div>

You can also add, remove, and append to element attributes. For example if we have: <div class="foo"></div> , below are some example transformations:

• hq "div [class+]" "hidden" gives <div class="foo hidden"></div>
• hq ".foo [id]" "bar" gives <div id="bar" class="foo"></div>
• hq "* [class!]" "foo" gives <div></div>

This module exports several constructors for common types of node transformations. These constructors simply give you back a Node -> Node , which you can then apply however you choose.

Constructors

class MakeTransformer a where

Methods

hq :: String -> a -> [Node] -> [Node]

Instances

MakeTransformer String

MakeTransformer Node

MakeTransformer Group

MakeTransformer [[Node] -> [Node]]

MakeTransformer [String]

MakeTransformer [Node]

MakeTransformer a => MakeTransformer (Maybe a)

MakeTransformer ([Node] -> [Node])

data Group

Constructors

Group [Node]

Instances

MakeTransformer Group

Values

nothing is handy for deleting a node from the tree, you cna replace it with nothing, e.g. hq ".foo" nothing

nothing :: [Node]
