name :: Traversal' (UNode t) t

Traverses the name of an Element. This is as an Affine, or 0-or-1 target, Traversal. In regex terms, you can think of it like the ? suffix modifier.

attributes :: Traversal' (UNode t) (UAttributes t)

Traverses to the list of attributes of an Element. This is as an Affine, or 0-or-1 target, Traversal. In regex terms, you can think of it like the ? suffix modifier.

children :: Traversal' (UNode t) [UNode t]

Traverses the children of an Element. This is as an Affine, or 0-or-1 target, Traversal. In regex terms, you can think of it like the ? suffix modifier.

text :: Prism' (UNode t) t

Prismatic access to the text of a Text node. This is more powerful than name, children, and attributes since it can be Reviewed.

allNodes :: UNode t -> [UNode t]

Produces a list of all UNodes in a XML tree. Synonym for universe.

named :: (Choice p, Applicative f, Eq t) => t -> Overloaded' p f (UNode t) (UNode t)

Traverses Elements which have a particular name.

parameterized :: (Choice p, Applicative f, Eq t, GenericXMLString t) => t -> t -> Overloaded' p f (UNode t) (UNode t)

parameterized k v traverses Elements which match the value v at the key k in their attributes.
