public class XMLInputHandler extends java.lang.Object implements SquiggleInputHandler
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.Modifier and Type | Class and Description |

XMLInputHandler.DocumentURIResolver
