Example 1 with StylesheetPIHandler

use of org.apache.xml.utils.StylesheetPIHandler in project robovm by robovm.

the class TransformerFactoryImpl method getAssociatedStylesheet.

   * the given criteria.  Note that it is possible to return several stylesheets
   * that match the criteria, in which case they are applied as if they were
   * a list of imports or cascades.
   *
   * <p>Note that DOM2 has it's own mechanism for discovering stylesheets.
