Iterating Through HTML Documents
After you have the HTML document loaded, in addition to just displaying the content inside a
JEditorPane
, you may find it necessary to parse through the content yourself to pull out various
pieces. The
HTMLDocument
supports at least two manners of iteration through the content via
the
HTMLDocument.Iterator
and
ElementIterator
classes.
HTMLDocument.Iterator Class
To use the
HTMLDocument.Iterator
, you ask an
HTMLDocument
to give you the iterator for a specific
HTML.Tag
. Then, for each instance of the tag in the document, you can look at the attributes of
the tag.
The
HTML.Tag
class includes 76 class constants for all the standard HTML tags (which the
HTMLEditorKit
understands), such as
HTML.Tag.H1
for the
<H1>
tag. These constants are listed in
Table 16-7.
