Class XSLTransformer

java.lang.Object
  extended by org.jdom.transform.XSLTransformer

public class XSLTransformer
extends java.lang.Object

A convenience class to handle simple transformations. The JAXP TrAX classes have more bells and whistles and can be used with JDOMSource and JDOMResult for advanced uses. This class handles the common case and presents a simple interface. XSLTransformer is thread safe and may be used from multiple threads.


 XSLTransformer transformer = new XSLTransformer("file.xsl");

 Document x2 = transformer.transform(x);  // x is a Document
 Document y2 = transformer.transform(y);  // y is a Document
 
JDOM relies on TrAX to perform the transformation. The javax.xml.transform.TransformerFactory Java system property determines which XSLT engine TrAX uses. Its value should be the fully qualified name of the implementation of the abstract javax.xml.transform.TransformerFactory class. Values of this property for popular XSLT processors include:

This property can be set in all the usual ways a Java system property can be set. TrAX picks from them in this order:

  1. Invoking System.setProperty( "javax.xml.transform.TransformerFactory", "classname")
  2. The value specified at the command line using the -Djavax.xml.transform.TransformerFactory=classname option to the java interpreter
  3. The class named in the lib/jaxp.properties properties file in the JRE directory, in a line like this one:
    javax.xml.parsers.DocumentBuilderFactory=classname
  4. The class named in the META-INF/services/javax.xml.transform.TransformerFactory file in the JAR archives available to the runtime
  5. Finally, if all of the above options fail, a default implementation is chosen. In Sun's JDK 1.4, this is Xalan 2.2d10.

Constructor Detail

XSLTransformer

public XSLTransformer(java.lang.String stylesheetSystemId)
               throws XSLTransformException
Creates a transformer for a given stylesheet system id.

Parameters:
stylesheetSystemId - source stylesheet as a Source object
Throws:
XSLTransformException - if there's a problem in the TrAX back-end

XSLTransformer

public XSLTransformer(java.io.InputStream stylesheet)
               throws XSLTransformException

This will create a new XSLTransformer by reading the stylesheet from the specified InputStream.

Parameters:
stylesheet - InputStream from which the stylesheet is read.
Throws:
XSLTransformException - when an IOException, format error, or something else prevents the stylesheet from being compiled

XSLTransformer

public XSLTransformer(java.io.Reader stylesheet)
               throws XSLTransformException

This will create a new XSLTransformer by reading the stylesheet from the specified Reader.

Parameters:
stylesheet - Reader from which the stylesheet is read.
Throws:
XSLTransformException - when an IOException, format error, or something else prevents the stylesheet from being compiled

XSLTransformer

public XSLTransformer(java.io.File stylesheet)
               throws XSLTransformException

This will create a new XSLTransformer by reading the stylesheet from the specified File.

Parameters:
stylesheet - File from which the stylesheet is read.
Throws:
XSLTransformException - when an IOException, format error, or something else prevents the stylesheet from being compiled

XSLTransformer

public XSLTransformer(Document stylesheet)
               throws XSLTransformException

This will create a new XSLTransformer by reading the stylesheet from the specified Document.

Parameters:
stylesheet - Document containing the stylesheet.
Throws:
XSLTransformException - when the supplied Document is not syntactically correct XSLT
