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.

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