Package com.day.cq.wcm.designimporter.parser.taghandlers

Class StyleTagHandler

java.lang.Object

com.day.cq.wcm.designimporter.parser.taghandlers.StyleTagHandler

All Implemented Interfaces:

EntryTagHandler, HTMLContentProvider, TagHandler

public class StyleTagHandler
extends Object
implements TagHandler, EntryTagHandler, HTMLContentProvider

The style tag handler is used to pull out the inline page styles defined within the style tag of the input HTML document.

This tag handler is registered against the markup of type invalid input: '<' style >. That implies this tag handler will come into action whenever the design importer framework encounters an HTML tag matching the rule this handler is defined against.
