In this section, you will learn about the XML Style Sheet Translation(XSLT)APIs.In this section, you will learn about the XML Style Sheet Translation(XSLT)APIs.
The XSLT APIs are defined in the following packages:
|javax.xml.transform||Defines the TransformerFactory and Transformer classes. These classes are used to get a object for doing transformations. After creating a transformer object, its transform() method is invoked. This method provides an input (source) and output (result).|
|javax.xml.transform.dom||Defines classes used to create input and output objects from a DOM.|
|javax.xml.transform.sax||Defines classes used to create input from a SAX parser and output objects from a SAX event handler.|
|javax.xml.transform.stream||Defines classes used to create input and output objects from an I/O stream.|
The diagram shows the working of the XSLT APIs .
A TransformerFactory object is instantiated, and used to create a Transformer. The source (input) object acts as the input to the transformation process. This object is created from SAX reader, from a DOM, or from an input stream.
The output (result) object is the result of this transformation process. This object can be a SAX event handler, a DOM, or an output stream. Transformer is created from a set of transformation instructions. If it is created without any specific instructions, then the transformer object simply copies the source to the result.
