Class XMLInputHandler

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.

Nested Class Summary
class	XMLInputHandler.DocumentURIResolver Implements the URIResolver interface so that relative urls used in transformations are resolved properly.

Method Detail

accept

public boolean accept(File f)

Returns true if the input file can be handled by the handler

accept

public boolean accept(ParsedURL purl)

Returns true if the input URI can be handled by the handler

accept

public boolean accept(String path)

Return true if the resource with the given path can be handled.

checkAndPatch

protected void checkAndPatch(Document doc)

This method checks that the generated content is SVG. This method accounts for the fact that the root svg's first child is the result of the transform. It moves all its children under the root and sets the attributes

extractXSLProcessingInstruction

protected String extractXSLProcessingInstruction(Document doc)

Extracts the first XSL processing instruction from the input XML document.

getDescription

public String getDescription()

Returns a description for this handler

getHandledExtensions

public String[] getHandledExtensions()

Returns the list of file extensions handled by this handler

getHandledMimeTypes

public String[] getHandledMimeTypes()

Returns the list of mime types handled by this handler.

handle

public void handle(ParsedURL purl, JSVGViewerFrame svgViewerFrame)

Handles the given input for the given JSVGViewerFrame
