Hi,
I made a quick implementation of the <svg:handler> and <ev:listener>
elements as proposed for SVG Tiny 1.2 to the extend allowed by the not
so good Working Draft <http://www.w3.org/TR/SVGMobile12/script.html>...
A simple example would be
<!DOCTYPE svg [ <!ATTLIST handler id ID #IMPLIED> ]>
<svg
xmlns = "http://www.w3.org/2000/svg";
xmlns:xlink = 'http://www.w3.org/1999/xlink'
xmlns:ev = "http://www.w3.org/2001/xml-events";
>
<defs>
<handler id="test">
evt.target.setAttributeNS(null, 'fill', 'green');
</handler>
</defs>
<rect id="obs1" height="100" width="100" x="0"/>
<a xlink:href="http://www.w3.org";>
<rect id="obs2" height="100" width="100" x="100"/>
</a>
<rect id="obs3" height="100" width="100" x="200"/>
<ev:listener observer="#obs1" event="click" handler='#test' />
<ev:listener observer="#obs2" event="click" defaultAction='cancel' />
<ev:listener observer="#obs3" event="click" handler='#test' />
</svg>
This is at http://www.bjoernsworld.de/temp/xml-events-01.svg which uses
http://www.bjoernsworld.de/temp/svg+xml-events.es to enable use of these
elements in non-compliant SVG 1.0/1.1 viewers like Opera9, Firefox 1.5
and ASV6. In compliant viewers like Batik it won't work (unless you use
only the ev:listener element).
There is some code to handle mutations of the elements and the document
(including listener registration during progressive download) but it
turns out that there are too many problems with existing implementations
and specifications that this is not really feasible, so some of the code
is missing and/or not used as intended.
The code also has an implementation of the DOM Level 3 Core Node method
lookupNamespaceURI if you are into namespaces that might be of interest.
The code is available under the GPL and might eventually end up in the
SVG QA project <http://sf.net/projects/svg-qa>. I am not likely to main-
tain this code, if you'd like to, please drop me a mail.
regards,
