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
