Constructor Detail

CssSelector

public CssSelector(List<ICssSelectorItem> selectorItems)

Creates a new CssSelector instance.

Parameters:

selectorItems - the selector items

CssSelector

public CssSelector(String selector)

Method Detail

matches

public boolean matches(INode element)

Description copied from interface: ICssSelector

Checks if a node matches the selector.

Parameters:

element - the node

Returns:

true, if the selector is a match for the node

matchesWithinScope

public boolean matchesWithinScope(INode element,
                                  INode scope)

Checks if the node matches this selector, but limits ancestor traversal so that it never goes above the provided scope node.

This is primarily used to implement :has(...) correctly: when matching a candidate descendant against an argument selector, ancestor combinators must not escape the :has() scope element.

Parameters:

element - the element to match

scope - the scope boundary (inclusive). If null, behaves like matches(INode).

Returns:

true if the element matches within the given scope, false otherwise

notMatches

public boolean notMatches(INode element)

Checks if the node not matches all the selectors.

Parameters:

element - the node

Returns:

true, if node doesn't match all the selectors
