Class FlyingSaucerMetadataCreationListener

java.lang.Object

org.xhtmlrenderer.pdf.DefaultPDFCreationListener

er.pdf.builder.FlyingSaucerMetadataCreationListener

All Implemented Interfaces:

org.xhtmlrenderer.pdf.PDFCreationListener

public class FlyingSaucerMetadataCreationListener
extends org.xhtmlrenderer.pdf.DefaultPDFCreationListener

Implements PDFCreationListener to extract metadata values from the input XHTML, and inserts those values into the resulting PDF. Specifically, XHTML meta tags with the following name attributes will have their content attributes inserted as the corresponding PDF metadata keys:

• title
• author
• subject
• creator
• descriptions
• keywords

For example, the following XHTML fragment would set the title, author and subject metadata keys in the PDF output:

 
 <meta name="title" content="Foo Sales" />
 <meta name="author" content="John Doe" />
 <meta name="subject" content="Monthly sales of Foo" />
 
 

Further, in the absence of a "title" meta element, the content of the title element will be used instead. That is, the following fragment would produce the same output:

 
 <title>Foo Sales</title>
 <meta name="author" content="John Doe" />
 <meta name="subject" content="Monthly sales of Foo" />
 
 

This class is based on code posted to the Flying Saucer project wiki, and is assumed to be in the public domain.
