DOMNormalizerpublic class DOMNormalizer extends Object implements org.apache.xerces.xni.XMLDocumentHandler| This class adds implementation for normalizeDocument method.
It acts as if the document was going through a save and load cycle, putting
the document in a "normal" form. The actual result depends on the features being set
and governing what operations actually take place. See setNormalizationFeature for details.
Noticeably this method normalizes Text nodes, makes the document "namespace wellformed",
according to the algorithm described below in pseudo code, by adding missing namespace
declaration attributes and adding or changing namespace prefixes, updates the replacement
tree of EntityReference nodes, normalizes attribute values, etc.
Mutation events, when supported, are generated to reflect the changes occuring on the
document.
See Namespace normalization for details on how namespace declaration attributes and prefixes
are normalized.
NOTE: There is an initial support for DOM revalidation with XML Schema as a grammar.
The tree might not be validated correctly if entityReferences, CDATA sections are
present in the tree. The PSVI information is not exposed, normalized data (including element
default content is not available). |
