The following selectors are supported: * AST node type: ForStatement * wildcard: * * attribute existence: [attr] * attribute value: [attr="foo"] or [attr=123] * attribute regex: [attr=/foo.*/] or (with flags) [attr=/foo.*/is] * attribute conditions: [attr!="foo"], [attr>2], [attr<3], [attr>=2], or [attr<=3] * nested attribute: [attr.level2="foo"] * field: FunctionDeclaration > Identifier.id * First or last child: :first-child or :last-child * nth-child (no ax+b support): :nth-child(2) * nth-last-child (no ax+b support): :nth-last-child(1) * descendant: ancestor descendant * child: parent > child * following sibling: node ~ sibling * adjacent sibling: node + adjacent * negation: :not(ForStatement) * has: :has(ForStatement) * matches-any: :matches([attr] > :first-child, :last-child) * subject indicator: !IfStatement > [name="foo"] * class of AST node: :statement, :expression, :declaration, :function, or :pattern
