Description
This module provides functions for validating XML documents represented as XmlTree. Unlike other popular XML validation tools the validation functions return a list of errors instead of aborting after the first error was found. Note: The validation process has been split into validation and transformation! If `validate` did not report any errors, `transform` should be called, to change the document the way a validating parser is expected to do.
Synopsis
getDTDSubset :: XmlArrow
validate :: XmlArrow
validateDTD :: XmlArrow
validateDoc :: XmlArrow
removeDoublicateDefs :: XmlArrow
transform :: XmlArrow
Documentation
getDTDSubset :: XmlArrow | Source
validate :: XmlArrow | Source
Main validation filter. Check if the DTD and the document are valid. returns : a function which expects a complete document as XmlTree input and returns a list of all errors found.
validateDTD :: XmlArrow | Source
Check if the DTD is valid. returns : a function which expects an XmlTree from the parser as input and returns a list of all errors found in the DTD.
validateDoc :: XmlArrow | Source
Check if the document corresponds to the given DTD. returns : a function which expects a complete document as XmlTree input and returns a list of all errors found in the content part.
removeDoublicateDefs :: XmlArrow | Source
Removes doublicate declarations from the DTD which first declaration is binding. This is the case for ATTLIST and ENTITY declarations. returns : A function that replaces the children of DOCTYPE nodes by a list where all multiple declarations are removed.
transform :: XmlArrow | Source
filter for transforming a document with respect to the given DTD. Validating parsers are expected to normalize attribute values and add default values. This function should be called after a successful validation. returns : a function which expects a complete XML document tree and returns the transformed XmlTree
