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 (rowencnext) {
        row[1] = row[1].toString();
        console.log(row);
        next();
    }))
;

this html:

<table>

  <tr><td>there</td></tr>
  <tr><td>it</td></tr>
  <tr><td>is</td></tr>
</table>

methods

var tokenize = require('html-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.
