Where basic filters are based mainly on the type of node or its position in the result set, content filters are based on node value or surrounding hierarchical structure.
- a:contains(“About Us"); selects all a nodes where the node value contains the substring “About Us".
- img:empty selects all img nodes that contain no child nodes (including text nodes).
- li:has(a:contains(“About Us")) selects all li nodes that contain an a node with the substring “About Us" in its node value.
- li:parent selects all li nodes that contain child nodes (including text nodes).
