Squash all contents of a Document into a single Terminal

squashDocumentOn :: forall a. Monoid a => (Document a -> Bool) -> Document a -> Document a Source #

Squash all contents of a Document which matches the predicate See also squashDocument

Arguments

 :: Text Identifier to search for -> Document a Document to search in -> [Document a]

Looks up nested Documents with a particular identifier. NB: Will not recurse into matching documents.

Similar to lookupDocument, lookupDocument' will find a Document with a particular identifier. This, however, will only find immediate children and will not recurse.
