## org.apache.batik.apps.svgbrowser
Class XMLInputHandler

    java.lang.Object
      org.apache.batik.apps.svgbrowser.XMLInputHandler

All Implemented Interfaces:
  SquiggleInputHandler

public class XMLInputHandler
extends java.lang.Object
implements SquiggleInputHandler

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

### getHandledMimeTypes

    public java.lang.String[] getHandledMimeTypes()

  Returns the list of mime types handled by this handler.

  Specified by:
    `getHandledMimeTypes` in interface `SquiggleInputHandler`

### getHandledExtensions

    public java.lang.String[] getHandledExtensions()

  Returns the list of file extensions handled by this handler

  Specified by:
    `getHandledExtensions` in interface `SquiggleInputHandler`

### getDescription

    public java.lang.String getDescription()

  Returns a description for this handler

  Specified by:
    `getDescription` in interface `SquiggleInputHandler`

### accept

    public boolean accept(java.io.File f)

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

  Specified by:
    `accept` in interface `SquiggleInputHandler`

### accept

    public boolean accept(ParsedURL purl)

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

  Specified by:
    `accept` in interface `SquiggleInputHandler`
  Parameters:
    `purl` - URL describing the candidate input

### accept

    public boolean accept(java.lang.String path)

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

### handle

    public void handle(ParsedURL purl,
                       JSVGViewerFrame svgViewerFrame)
                throws java.lang.Exception

  Handles the given input for the given JSVGViewerFrame

  Specified by:
    `handle` in interface `SquiggleInputHandler`
  Throws:
    `java.lang.Exception`

### checkAndPatch

    protected void checkAndPatch(org.w3c.dom.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 java.lang.String extractXSLProcessingInstruction(org.w3c.dom.Document doc)

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