public class FragmentExtractorTransformer
The transformation half of the FragmentExtractor. This transformer recieves an incoming stream of xml and replaces fragments with an fragment extractor locator pointing to the fragments. The extracted fragments are identified by their element name and namespace URI. The default is to extract SVG images ("svg" elements in namespace "http://www.w3.org/2000/svg"), but this can be overriden in the configuration:
<extract-uri>http://my/namespace/uri</extract-uri> <extract-element>my-element</extract-element>Fragment extractor locator format is following:
<fe:fragment xmlns:fe="http://apache.org/cocoon/fragmentextractor/2.0" fragment-id="..."/>
