Cascade is a pure Java implementation of CSS Selectors operating on W3C DOM.
Selector selector = Selector.compile("div p");
Document doc = ... /* doc is an instance of org.w3c.dom.Document */
List<Element> selected = selector.select(doc.getDocumentElement());- Compliant with W3C Selectors Level 3.
- Operating on standard W3C DOM interface defined in
org.w3c.dompackage. - Simple and intuitive API.
- Optimization is performed when selectors are compiled.
- Supports namespace.
- Compatible with documents provided by
javafx.scene.web.WebEngine. - Passed 700+ test cases.
For more detail, please see API documentation
- Java 8 or higher.
