I'm wondering if there's a jQuery-like css selector that can be used in C#.
Currently, I'm parsing some html strings using regex and thought it would be much nicer to have something like the css selector in jQuery to match my desired elements.
Update 10/18/2012
CsQuery is now in release 1.3. The latest release incorporates a C# port of the validator.nu HTML5 parser. As a result CsQuery will now produce a DOM that uses the HTML5 spec for invalid markup handling and is completely standards compliant.
Original Answer
Old question but new answer. I've recently released version 1.1 of CsQuery, a jQuery port for .NET 4 written in C# that I've been working on for about a year. Also on NuGet as "CsQuery"
The current release implements all CSS2 & CSS3 selectors, all jQuery extensions, and all jQuery DOM manipulation methods. It's got extensive test coverage including all the tests from jQuery and sizzle (the jQuery CSS selection engine). I've also included some performance tests for direct comparisons with Fizzler; for the most part CsQuery dramatically outperforms it. The exception is actually loading the HTML in the first place where Fizzler is faster; I assume this is because fizzler doesn't build an index. You get that time back after your first selection, though.
There's documentation on the github site, but at a basic level it works like this:
Create from a string of HTML
CQ dom = CQ.Create(htmlString);
Load synchronously from the web
CQ dom = CQ.CreateFromUrl("http://www.jquery.com");
Load asynchronously (non-blocking)
CQ.CreateFromUrlAsync("http://www.jquery.com", responseSuccess => {
Dom = response.Dom;
}, responseFail => {
..
});
Run selectors & do jQuery stuff
var childSpans = dom["div > span"];
childSpans.AddClass("myclass");
the CQ
object is like thejQuery object. The property indexer used above is the default method (like $(...)
.
Output:
string html = dom.Render();
