methods

var trumpet = require('trumpet')

var tr = trumpet(fn)

Create a new trumpet stream. This stream is readable and writable. Pipe an html stream into tr and get back a transformed html stream.

Optionally supply a function fn(node) that will get raw parsing events.

node is an object with these keys:

type - 'open', 'close', or 'text'
source - source string of the present parse event from the input stream
name - name of the html element (div, span, ...)
attributes - attributes from the html element
write(s) - write text to the output stream
parser - the raw sax parser object

These nodes are different from the higher-level nodes you get with .select().

tr.select(selector, fn)

Fire fn(node) for every element in the html stream that matches the css selector.

The nodes are described in the nodes section of this document.

nodes

node.name

The name of the html element node, such as 'div' or 'span'.

node.attributes

An object with all the html attributes.

For example,

<img src="/beep.png" width="32" height="32">

has an attribute object of:

{ src : 'beep.png', width : '32', height : '32' }

node.html(cb)

Get the inner text and html for the element, which may not have arrived yet.

cb(text) fires when the inner contents are ready.
