Hello... I'm trying to get Xerces to validate an xml against a schema. I'm following an example I found on the web. http://www-106.ibm.com/developerworks/xml/library/x-tipsch.html The parser seems to check if the xml is well-formed but not check if the xml follows the related schema. When I modify the XML shouldn't I get an exception saying it no longer follows the schema? Here is the java code.
