Interface | Description |
---|---|
XmlBuilder |
An XmlBuilder is an interface that can be implemented by classes
that convert between XmlElements and some internal
data representation.
|
Class | Description |
---|---|
AbstractXmlBuilder |
An abstract implementation of the XmlBuilder interface that gets
and sets a delegate, leaves the build method abstract, and doesn't
support the generate method.
|
CompositeBuilder |
CompositeBuilder is a non-validating parser that uses other
builders to parse and generate XML files from arbitary collections
of objects.
|
XmlDemo |
A simple program that you can run to illustrate the operation
of the files in this package.
|
XmlDocument |
An XMLDocument is an in-memory representation of an XML document.
|
XmlElement |
An XmlElement is a node of a tree representing an XML file.
|
XmlReader |
An XmlReader reads a character stream and constructs the internal
data of an XmlDocument.
|
XmlUtilities |
A collection of utility methods for XML-related
operations.
|
XmlWriter |
Given a tree of XmlElements, an object of this class generates
the equivalent XML into an output stream.
|
The XmlReader class will parse any legal XML file (containing a reference to its DTD) and produce a parsed tree of XmlElements which it inserts into the document. The application can then traverse the tree to extract data or to build its own internal data structure. Here is an example illustrating a typical use of the XmlReader to process an XML file:
XmlDocument document = new XmlDocument(new URL("file:/...")); XmlReader reader = new XmlReader(); reader.setVerbose(true); reader.parse(document); if (reader.errorCount > 0) { ...do something... return; } XmlElement root = document.getRoot(); for (Iterator i = root.elements(); i.hasNext();) { ... process each child element... }
To create an XML file, the application creates a tree of XmlElements and inserts it into an XmlDocument. It then calls the write() method with a Writer object. Here is an example illustrating a typical use:
XmlElement root = new XmlElement(); ... Add child elements to the root ... XmlDocument document = new XmlDocument("file:/..."); document.setRoot(root); XmlWriter writer = new XmlWriter(); writer.setVerbose(true); writer.write(document);
