javax.swing.text.html.HTMLDocument: how do I find a html image map in a document?

Question

I'm trying to find a html map in a HTMLDocument:

<html>
<map name="imagemap"></map>
</html>

With hdoc my HTMLDocument, I tried the following to get the map but it keeps returning null:

hdoc.getElement(hdoc.getDefaultRootElement(), HTML.Attribute.NAME, "imagemap")

Am I doing something wrong? How do I get the map?

1) For better help sooner, [edit] to add a [MCVE] or [Short, Self Contained, Correct Example](http://www.sscce.org/). 2) A smart HTML interpreter would entirely remove empty elements. — Andrew Thompson, Mar 30 '20 at 11:39
@AndrewThompson I don't think a SSCE would help. Either I am calling the method correctly, or I am not. — Guillaume F., Mar 30 '20 at 11:55

You can't get the <map> nodes with getElement. They all get deleted by the HTML interpreter, even those in use.

Instead, use

((Hashtable) hdoc.getDocumentProperties().get("__MAP__")).get("#imagemap");

Unfortunately, the Map you get from this is a package-private class, so you can't use the data unless you do some reflection.
