Class OAXMLReader

java.lang.Object

com.viaoa.xml.OAXMLReader

public class OAXMLReader
extends Object

OAXMLReader using a SAXParser to parse and automatically create OAObjects from an XML file. This will do the following to find the existing object: 1: if OAProperty.importMatch, then it will search to find a matching object 2: if objectId props, then it will search to find a matching object 3: use guid if not found, then a new object will be created. NOTE: 20230917 Use OAXml instead (based on OAJson that uses jackson)
