checkAttributeValue :: XmlTrees -> XmlTree -> XmlFilter

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

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
