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. At this time, the library is BETA quality.

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

Examples

// 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 = htmlDocument.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");
