In this respect i am unsure how you can create a general validating mechanism unless you keep a map of known JAXB class to Schema instance. We have resolved this issue without needing to maintain a map of JAXB classes.

You will have to create the Schema instances from the correspondingly available XSD, more info can be found here [1]. We implemented a Validation Event Collector, and set this to handle validation events coming from the unmarshaller.

The two most common types of nodes in XML document are element nodes and text nodes.

With Java DOM API we can create nodes, remove nodes, change their contents, and traverse the node hierarchy.

*/ try catch (Unsupported Operation Exception e) catch (No Such Method Error e) { /* This is OK; older versions of the parser do not support XInclude at * all.

I've dealt with a few XML APIs in Java, but I don't have a good understanding of all the frameworks available in Java for dealing with XML for whatever purpose (e.g. Can anyone highlight the most popular Java XML APIs and give a quick description of what they're intended to be used for?Let's dive right into code: "); Document Builder Factory dbf = Document Builder Instance(); Document Builder db = Document Builder(); Document dom = db.parse(new Input Source(xml)); println("root element name = " Document Element()Node Name()); And that's all you need to parse a simple XML string.However, chances are good that you're not parsing simple literal strings, so read on …Useful if you're unmarshalling JAXB objects or extracting data from a large file, not so useful if you're exploring a data structure.The downside of DOM, of course, is that it's all in memory, and the DOM implementation adds quite a bit to the memory footprint of the data.
