Text.XML.HXT.DTDValidation.AttributeValueValidation

Description

This module provides functions for validating attributes.

The main functions are:

- Check if the attribute value meets the lexical constraints of its type
- Normalization of an attribute value

Synopsis

- checkAttributeValue :: XmlTrees -> XmlTree -> XmlArrow
- normalizeAttributeValue :: Maybe XmlTree -> String -> String

# Documentation

checkAttributeValue :: XmlTrees -> XmlTree -> XmlArrow Source #

Checks if the attribute value meets the lexical constraints of its type.

- 1.parameter dtdPart : the children of the `DOCTYPE` node
- 2.parameter attrDecl : the declaration of the attribute from the DTD
- returns : a function which takes an element (XTag or XDTD ATTLIST), checks if the attribute value meets the lexical constraints of its type and returns a list of errors

normalizeAttributeValue :: Maybe XmlTree -> String -> String Source #

Normalizes an attribute value with respect to its type. (3.3.3 / p.29 in Spec)

- 1.parameter attrDecl : the declaration of the attribute from the DTD. Expected is a list. If the list is empty, no declaration exists.
- 2.parameter value : the attribute value to be normalized
- returns : the normalized value
