public static class HTMLEditorKit.InsertHTMLTextAction

extends HTMLEditorKit.HTMLTextAction

InsertHTMLTextAction can be used to insert an arbitrary string of HTML into an existing HTML document. At least two HTML.Tags need to be supplied. The first Tag, parentTag, identifies the parent in the document to add the elements to. The second tag, addTag, identifies the first tag that should be added to the document as seen in the HTML string. One important thing to remember, is that the parser is going to generate all the appropriate tags, even if they aren't in the HTML string passed in.

For example, lets say you wanted to create an action to insert a table into the body. The parentTag would be HTML.Tag.BODY, addTag would be HTML.Tag.TABLE, and the string could be something like <table><tr><td></td></tr></table>.

There is also an option to supply an alternate parentTag and addTag. These will be checked for if there is no parentTag at offset.
