setAttribute in tinymce not working for sitePublisher components

Vishu1

My requirement is, if author inputs content with anchor tags in the textarea field(tinymce), when i click on the plugin button, the postprocessor should add some custom parameters to the tags only.

So if i enter below content in the HTML view of the Textarea and update it:

GO

For this I have created a custom plugin. This custom plugin is working for DCT's.

But the same is not working for SitePublisher components.

The "editor_plugin_src.js" file of the plugin is getting called. I verified by putting some alerts.

To set the the parameters I am using below code:

if (o.get) {

tinymce.each(ed.dom.select('a', o.node), function(n) {

n.setAttribute('parameters','[\'$CONTEXT{thisComponent.name}\']');

n.setAttribute('analyticclass','analyseLink');

});

}

The "setAttribute" is not working for SP components.
