All Implemented Interfaces:
SquiggleInputHandler
public class XMLInputHandler extends Object implements SquiggleInputHandler
A SquiggleInputHandler that handles XSLT transformable XML documents. This implementation of the SquiggleInputHandler class handles XML files by looking for the first <?xml-stylesheet ... ?> processing instruction referencing an xsl document. In case there is one, the transform is applied to the input XML file and the handler checks that the result is an SVG document with an SVG root.
