A .NET library to select items from a node tree based on a CSS selector. The default implementation is based on HTMLAgilityPack and selects from HTML documents. There over 140 unit tests - see below for more information. The tests are based on the jQuery selector engine tests.
Fizzler supports .NET 2.0, 3.0, 3.5 and Mono.
Contributions are welcome in forms of:
- Increased selector support
- Implementation over an HTML-like hierarchical document model
- Re-factorings
- Improved tests
// Load the document using HTMLAgilityPack as normal
var html = new HtmlDocument();
html.LoadHtml(@"
<html>
<head></head>
<body>
<div>
<p class='content'>Fizzler</p>
<p>CSS Selector Engine</p></div>
</body>
</html>");
// Fizzler for HtmlAgilityPack is implemented as the
// QuerySelectorAll extension method on HtmlNode
var document = html.DocumentNode;
// yields: [<p class="content">Fizzler</p>]
document.QuerySelectorAll(".content");
// yields: [<p class="content">Fizzler</p>,<p>CSS Selector Engine</p>]
document.QuerySelectorAll("p");
// yields empty sequence
document.QuerySelectorAll("body>p");
// yields [<p class="content">Fizzler</p>,<p>CSS Selector Engine</p>]
document.QuerySelectorAll("body p");
// yields [<p class="content">Fizzler</p>]
document.QuerySelectorAll("p:first-child");View them here (Fizzler.Tests):
