Description of DBMS_XSLPROCESSOR

The Extensible Stylesheet Language Transformation (XSLT), describes rules for transforming a source tree into a result tree. A transformation expressed in XSLT is called a stylesheet. The transformation specified is achieved by associating patterns with templates defined in the stylesheet. A template is instantiated to create part of the result tree. This PL/SQL implementation of the XSL processor followed the W3C XSLT working draft (rev WD-xslt-19990813) and included the required behavior of an XSL processor in terms of how it must read XSLT stylesheets and the transformation it must effect.

The following is the default behavior for this PL/SQL XSL Processor:

• A result tree which can be accessed by DOM APIs is built
• Errors are not recorded unless an error log is specified; however, an application error will be raised if parsing fails
