Do you plan to implement this? What about selectors like 'ul > li' to grab immediate children?

I took a look at this earlier - this should be addressed in cheerio-soupselect. I'm hoping to close this bug this weekend.
Here's where the discussion will be: matthewmueller/cheerio-soupselect#7

I'm not understanding the feature/bug here. I thought that .children() was supposed to return only the immediate descendants (see here). Could you perhaps provide a code example?
Currently it seems as thought:
var cheerio = require("cheerio"),
$ = cheerio.load('<p><h1></h1><div><anotherd></anotherd></div></p>');
console.log($("p").children());Returns the appropriate result:
{ '0':
{ type: 'tag',
name: 'h1',
attribs: {},
parent:
{ type: 'tag',
name: 'p',
children: [Object],
attribs: {},
parent: [Object],
prev: null,
next: null },
prev: null,
next:
{ type: 'tag',
name: 'div',
children: [Object],
attribs: {},
parent: [Object],
prev: [Circular],
next: null },
children: [] },
'1':
{ type: 'tag',
name: 'div',
children: [ [Object] ],
attribs: {},
parent:
{ type: 'tag',
name: 'p',
children: [Object],
attribs: {},
parent: [Object],
prev: null,
next: null },
prev:
{ type: 'tag',
name: 'h1',
attribs: {},
parent: [Object],
prev: null,
next: [Circular],
children: [] },
next: null },
length: 2 }

It's the selector that looks through the children when it shouldn't. Try:
var $ = cheerio.load('<html><body><h2 class = "header">Header</h2></body></html>')
$('html').children('.header');
I think this is best managed by adding a depth parameter in cheerio-soupselect. Anything else seems like a hack in the .find() function.

high fives for whoever implements depth + more css3-style selectors ("ul > li")

You should be able to use Array.prototype.filter with the method you get from CSSselect as the only argument. (That should also be the most performant way.)

This was indirectly resolved by commit 0464dd8, and an regression test was added in commit 024ac31.
