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
- checkAttributeValue :: XmlTrees -> XmlTree -> XmlArrow
- normalizeAttributeValue :: Maybe XmlTree -> String -> String
Documentation
checkAttributeValue :: XmlTrees -> XmlTree -> XmlArrowSource
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 -> StringSource
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
