Parsing text in the Enamex data format. Each node is enclosed between opening and closing tags with tag name representing the label and contents representing children of the node. Both leaf and label values should be escaped by prepending the \ character before special >, <, \ and space characters.
Example:
>>>
:m Data.Tree Data.Text Text.Named.Enamex
>>>
let drawIt = putStr . drawForest . fmap (fmap unpack) . parseForest
>>>
drawIt $ pack "<x>w1.1\\ w1.2</x> <y><z>w2</z> w3</y>"
x | `- w1.1 w1.2 , y | +- z | | | `- w2 | `- w3
- parseForest :: Text -> Forest
- parseEnamex :: Text -> [Forest]
- mapTwo :: (a -> b) -> (a -> c) -> Tree a -> Tree (Either b c)
