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.
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.
DTDs and XSD were normally accessed as configuration options in Simple API for XML (SAX), Document Object Model (DOM), and Java™ API for XML Processing (JAXP). Schematron might use the Transformations API for XML(Tr AX); and still other schema languages required programmers to learn still more APIs, even though they were performing essentially the same operation.
Java 5 introduced the package to provide a schema-language-independent interface to validation services.
Note that only whitespace which is directly contained within element content that has an element only content model (see XML Rec 3.2.1) will be eliminated. Just before we start parsing the XML document, we specify the XML Schema file by using the set Attribute(JAXP_SCHEMA_SOURCE,...) of the factory. * */ public class XMLSchema Validator What we do here is simply parsing an XML document. We request the Document Builder Factory to validate a given XML document against a given XML Schema document by invoking the set Validate() method of the factory. It enables you to quickly check that input is roughly in the form you expect and quickly reject any document that is too far away from what your process can handle.If there's a problem with the data, it's better to find out earlier than later.
