Code

The following are Java examples that show how to manipulate XML data in a programming environment. All require a few Java archives which can be found in EXIST_HOME/lib.

• SAX and DOM examples. A simple SAX example, and two very simple DOM programs. The SAX examples shows a content handler, and how to use it. The first DOM example serializes a DOM tree (don't use it in a real application!), and the second one modifies an XML document. See the comments. You must add the Xerces.jar archive in your CLASSPATH (look at EXIST_HOME/lib/endorsed).
  • SaxHandler.java, SaxExample.java
  • DomSerializer.java
  • DomPreorder.java
• The Xalan XSLT processor. The following example comes from the Xalan distribution. It shows how to apply an XSLT transformation to an XML document via the Xalan/Java API.
  You must add the xalan.jar, xercesImpl.jar, xml-apis.jar and serializer.jar archives in your classpath.
  • SimpleTransform.java, which applies birds.xsl to birds.xml.
  See the Xalan site for further examples and explanations.
• XML:DB (using eXist) examples. The following sample programs show how to access the eXist XML database. You must add the exist.jar, xmldb.jar, xmlrpc-1.2-patched.jar, and log4j-1.2.14.jar archives in your CLASSPATH. See the book appendix for further explanations, as well as the eXist documentation.
  • ExistAccess.java
  • ExistQuery.java
• Lucene examples.
  • MyLucene.java
  • Simple.java
• Hadoop MapReduce.
  • Authors.java (the map and reduce jobs)
  • AuthorsJob.java
• XProc.
  • skeleton.xpl
