Text.XML.HXT.DTDValidation.DocTransformation
Description
This module provides functions for transforming XML documents represented as XmlTree with respect to its DTD.
Transforming an XML document with respect to its DTD means:
- add all attributes with default values
- normalize all attribute values
- sort all attributes in lexical order
Note: Transformation should be started after validation.
Before the document is validated, a lookup-table is build on the basis of the DTD which maps element names to their transformation functions. After this initialization phase the whole document is traversed in preorder and every element is transformed by the XmlFilter from the lookup-table.
