transform stream to tokenize html

example

var fs = require('fs');
var tokenize = require('html-tokenize');
var through = require('through2');

fs.createReadStream(__dirname + '/table.html')
    .pipe(tokenize())
    .pipe(through.obj(function (row, enc, next) {
        row[1] = row[1].toString();
        console.log(row);
        next();

;

this html:

[ 'open', '<tbody>' ]
[ 'text', 'blah blah blah' ]
[ 'close', '</tbody>' ]
[ 'text', '\n  ' ]
[ 'open', '<tr>' ]
[ 'open', '<td>' ]
[ 'text', 'there' ]
[ 'close', '</td>' ]
[ 'close', '</tr>' ]
[ 'text', '\n  ' ]
[ 'open', '<tr>' ]
[ 'open', '<td>' ]
[ 'text', 'it' ]
[ 'close', '</td>' ]
[ 'close', '</tr>' ]
[ 'text', '\n  ' ]
[ 'open', '<tr>' ]
[ 'open', '<td>' ]
[ 'text', 'is' ]
[ 'close', '</td>' ]
[ 'close', '</tr>' ]
[ 'text', '\n' ]

methods

var tokenize = require('html-tokenize');

var t = tokenize()

Return a tokenize transform stream t that takes html input and produces rows of output. The output rows are of the form:

[ name, buffer ]

The input stream maps completely onto the buffers from the object stream.

The types of names are:

open
close
text

cdata, comments, and scripts all use 'open' with their contents appearing in subsequent 'text' rows.
