match a tokenized html stream with css selectors
var select = require('html-select');
var tokenize = require('html-tokenize');
var fs = require('fs');
fs.createReadStream(__dirname + '/page.html')
.pipe(tokenize())
.pipe(select('.content span', function (e) {
console.log('matched:', e);
}))
;with this html input:
<html>
<body>
<h1>whoa</h1>
<div class="content">
<span class="greeting">beep boop</span>
<span class="name">robot</div>
</div>
</body>
</html>
produces this output:
matched: { name: 'span', attributes: { class: 'greeting' } }
matched: { name: 'span', attributes: { class: 'name' } }
var select = require('html-select')Return a writable stream w that expects an object stream of
html-tokenize records as input.
cb(tag) fires on the same tick for each tag matching the css selector
selector. tag looks like:
{ name: 'input', attributes: { type: 'text', 'name': 'user', value: 'beep' } }The records are of the form:
$ echo -e '<html><body><h1>beep boop</h1></body></html>' | html-tokenize
["open","<html>"]
["open","<body>"]
["open","<h1>"]
["text","beep boop"]
["close","</h1>"]
["close","</body>"]
["close","</html>"]
["text","\n"]
except the second item in each record will be a Buffer if you get the results from html-tokenize directly.
