public class HTMLEventLinkTransformer
extends AbstractCopletTransformer

This transformer transforms html actions into events. The transformer listens for the element a and form. Links that only contain an anchor are ignored. In addition if a link has the attribute "external" with the value "true", the link is also ignored. TODO: Support target attribute

Method Detail

setup

public void setup(SourceResolver resolver,
                  Map objectModel,
                  String src,
                  Parameters par)
           throws ProcessingException,
                  SAXException,
                  IOException

Description copied from interface: SitemapModelComponent

Set the SourceResolver, objectModel Map, the source and sitemap Parameters used to process the request.

Specified by:

setup in interface SitemapModelComponent

Overrides:

setup in class AbstractSAXTransformer

Throws:

ProcessingException

SAXException

IOException

See Also:

SitemapModelComponent.setup(org.apache.cocoon.environment.SourceResolver, java.util.Map, java.lang.String, org.apache.avalon.framework.parameters.Parameters)

startElement

public void startElement(String uri,
                         String name,
                         String raw,
                         Attributes attr)
                  throws SAXException

Description copied from class: AbstractSAXTransformer

Process the SAX event. The namespace of the event is checked. If it is the defined namespace for this transformer, the AbstractSAXTransformer.startTransformingElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes) hook is called.

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class AbstractSAXTransformer

Parameters:

uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

name - The local name (without prefix), or the empty string if Namespace processing is not being performed.

raw - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

attr - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.

Throws:

SAXException

See Also:

ContentHandler.startElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes)

endElement

public void endElement(String uri,
                       String name,
                       String raw)
                throws SAXException

Description copied from class: AbstractSAXTransformer

Process the SAX event. The namespace of the event is checked. If it is the defined namespace for this transformer, the AbstractSAXTransformer.endTransformingElement(java.lang.String, java.lang.String, java.lang.String) hook is called.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class AbstractSAXTransformer

Parameters:

uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

name - The local name (without prefix), or the empty string if Namespace processing is not being performed.

raw - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

Throws:

SAXException

protected void createFormEvent(Attributes attributes)
                        throws SAXException

Throws:

SAXException

getLink

protected String getLink(String base,
                         String link)

isRemoteAnchor

protected boolean isRemoteAnchor(Attributes attributes)

Determine if the element is an url and if the url points to some remote source.

Parameters:

attributes - the attributes of the element

Returns:

true if the href url is an anchor pointing to a remote source
