Class Transform

java.lang.Object
  net.sf.saxon.Transform

Direct Known Subclasses:

DOMTransform, JDOMTransform, Transform

public class Transform
extends Object

This Transform class is the entry point to the Saxon XSLT Processor. This class is provided to control the processor from the command line.

The XSLT syntax supported conforms to the W3C XSLT 1.0 and XPath 1.0 recommendation. Only the transformation language is implemented (not the formatting objects). Saxon extensions are documented in the file extensions.html

Method Detail

main

public static void main(String[] args)
                 throws Exception

Main program, can be used directly from the command line.

The format is:

java net.sf.saxon.Transform [options] source-file style-file >output-file

followed by any number of parameters in the form {keyword=value}... which can be referenced from within the stylesheet.

This program applies the XSL style sheet in style-file to the source XML document in source-file.

Parameters:

args - List of arguments supplied on operating system command line

Throws:

Exception - Indicates that a compile-time or run-time error occurred

setFactoryConfiguration

public void setFactoryConfiguration(boolean schemaAware,
                                    String className)
                             throws RuntimeException

Set the configuration in the TransformerFactory. This is designed to be overridden in a subclass

Parameters:

schemaAware - True if the transformation is to be schema-aware

className - Name of the schema-aware Configuration class to be loaded. Designed for use by .NET; can normally be null.

Throws:

RuntimeException

doTransform

public void doTransform(String[] args,
                        String command)

Support method for main program. This support method can also be invoked from subclasses that support the same command line interface

Parameters:

args - the command-line arguments

command - the form of the command as written by the user, to be used in error messages

preprocess

public List preprocess(List sources)
                throws XPathException

Preprocess the list of sources. This method exists so that it can be overridden in a subclass

Parameters:

sources - the list of Source objects

Returns:

a revised list of Source objects

Throws:

XPathException

loadDocuments

public static Object loadDocuments(String sourceFileName,
                                   boolean useURLs,
                                   Configuration config,
                                   boolean useSAXSource)
                            throws TransformerException

Load a document, or all the documents in a directory, given a filename or URL

Parameters:

sourceFileName - the name of the source file or directory

useURLs - true if the filename argument is to be treated as a URI

config - the Saxon configuration

useSAXSource - true if the method should use a SAXSource rather than a StreamSource

Returns:

if sourceFileName represents a single source document, return a Source object representing that document. If sourceFileName represents a directory, return a List containing multiple Source objects, one for each file in the directory.

Throws:

TransformerException

processDirectoryAssoc

public void processDirectoryAssoc(List sources,
                                  File outputDir,
                                  ArrayList parameterList,
                                  String initialMode)
                           throws Exception

Process each file in the source directory using its own associated stylesheet

Parameters:

sources - The sources in the directory to be processed

outputDir - The directory in which output files are to be created

parameterList - List of parameters to be supplied to each transformation

initialMode - Initial mode for executing each transformation

Throws:

Exception - when any error occurs during a transformation

processFileAssoc

public void processFileAssoc(Source sourceInput,
                             String localName,
                             File outputFile,
                             ArrayList parameterList,
                             String initialMode)
                      throws TransformerException

Process a single source file using its associated stylesheet(s)

Parameters:

sourceInput - Identifies the source file to be transformed

localName - The local name of the file within the directory, excluding the file type suffix

outputFile - The output file to contain the results of the transformation

parameterList - List of parameters to be supplied to the transformation

initialMode - Initial mode for executing the transformation

Throws:

XPathException - If the transformation fails

TransformerException

now

public static long now()

Get current time in milliseconds

Returns:

processDirectory

public void processDirectory(List sources,
                             Templates sheet,
                             File outputDir,
                             ArrayList parameterList,
                             String initialTemplate,

                      throws TransformerException

Process each file in the source directory using the same supplied stylesheet

Parameters:
