valuecheckAttributeValue :: XmlTrees -> XmlTree -> XmlArrow
#

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

valuenormalizeAttributeValue :: Maybe XmlTree -> String -> String
#

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
