Universal.HtmlAgilityPack

CSS selector support for HtmlAgilityPack, bringing familiar CSS selector querying to HTML parsing.

Classes

CssSelectorToXPathConverter

Converts CSS selectors to equivalent XPath expressions for use with HTML parsing libraries.

var converter = new CssSelectorToXPathConverter();
string xpath = converter.Convert("div.main p:first-child");
// Returns: "//div[contains(concat(' ', normalize-space(@class), ' '), ' main ')]//p[position()=1]"

Extension Methods

QuerySelector / QuerySelectorAll

Adds CSS selector support to HtmlDocument and HtmlNode with familiar querySelector and querySelectorAll methods.

var doc = new HtmlDocument();
doc.LoadHtml("<div class='content'><p id='intro'>Hello</p><p>World</p></div>");

// Select single element
HtmlNode intro = doc.QuerySelector("#intro");
HtmlNode firstParagraph = doc.QuerySelector("div.content p");

// Select multiple elements  
IEnumerable<HtmlNode> allParagraphs = doc.QuerySelectorAll("p");
IEnumerable<HtmlNode> contentDivs = doc.QuerySelectorAll("div.content");

// Works on any HtmlNode
HtmlNode contentDiv = doc.QuerySelector(".content");
HtmlNode nestedParagraph = contentDiv.QuerySelector("p:first-child");

This implementation supports most CSS 4 constructs and returns actual HtmlNode references from the document (not copies), enabling direct manipulation of the DOM structure.
