Examples of XUpdateProcessor

org.exist.xupdate.XUpdateProcessor
Main class to pre-process an XUpdate request. XUpdateProcessor will parse the request via SAX and compile it into a set of {@link Modification} objects as returned by the {@link #parse(org.xml.sax.InputSource)}method. The modifications can then be executed via {@link Modification#process(org.exist.storage.txn.Txn)}. @author Wolfgang Meier
