##About
The cornet is a brass instrument very similar to the trumpet, distinguished by its conical bore, compact shape, and mellower tone quality. - Wikipedia
This project is demonstrating how to use a couple of my libraries to replace substack/node-trumpet
in just a couple of LOC.
Even better, there are some advantages over trumpet
:
- The ammount of usable CSS selectors is increased dramatically thanks to
fb55/CSSselect
. cornet
usesfb55/htmlparser2
, which is probably the fastest HTML parser currently available for node. And it's much less strict than thesax
module used bytrumpet
.- By using the great
MatthewMueller/cheerio
module, you can do everything with your document that would be possible with jQuery.
##Example
var Parser = require("htmlparser2").WritableStream,
Cornet = require("cornet"),
minreq = require("minreq"),
$ = require("cheerio");
var cornet = new Cornet();
minreq.get("http://github.com/fb55").pipe(new Parser(cornet));
cornet.remove("script"); //remove all scripts
//show all repos
cornet.select(".repo_list", function(elem){
$(elem).find("h3").each(function(i){
console.log("repo %d: %s", i, $(this).text());
});
});
