Method Detail

parseQuery

org.w3c.dom.Node parseQuery(org.w3c.dom.Node inputNode)
                      throws QueryException

Queries are re-structured according to de Morgan's rules, and are checked for overall structure (do this with a schema in future?). Any text nodes are removed, apart from the ones containing the attributes and terms, which have leading and trailing whitespace trimmed. Attribute values used are not checked here, or in ZSession, only in QueryBuilder.
