Non validating xml parser java
Document Builder Factory dbf = Document Builder Instance(); Namespace Aware(true); Validating(true); Document Builder db = Document Builder(); Error Handler(new Error Handler() ); Document dom = db.parse(new Input Source(xml)); is called “to report conditions that are not errors or fatal errors as defined by the XML recommendation.” I'm not entirely certain what those conditions might be, and have never seen this method invoked.The documentation goes on to say that it may be used by other components to report conditions that have nothing to do with the XML being parsed. In the real world an XML document isn't going to contain its own DTD.Parser will use a default Error Handler to print the first 10 errors.Please call the 'set Error Handler' method to fix this.For example, XML generated using simple string output in a Windows environment will probably be encoded in .Normally, this isn't an issue, especially if the XML is both produced and processed within the same organization.
The JDK's XML API predated namespaces, and due to backwards compatibility you must explicitly tell it that you want namespace-aware parsing: , not the parser.
Let validation do what it can, but ultimately your program must explicitly verify that an XML file contains the correct data.
The Document Type Definition is part of the XML specification.
root element name = music So, taking that advice, here's an error handler that will write all messages to the console.
In the real world, this wouldn't be very useful (and gives no more information than the default); generally the first few messages will tell you why the parser got off the rails.
