RE: [Htmlparser-user] Link Extraction from Tables w/ ver. 1.3

Hi Randall,

I faced very similar problems when I migrated to 1.3. Basically I
believe the structure now returned has more of a DOM face than a SAX one
as earlier. Earlier all nodes were available at the base level. Today
they are buried within other nodes. Hence your <A> is buried in the
<TABLE> tag and has to be extracted as a child of the <TABLE> tag.

Code for extracing link tag is given in documentation of node.
Reproducing it here for u:

NodeList collectionList =3D new NodeList();=20
 Node node;=20
 for (NodeIterator e =3D parser.elements(); e.hasMoreNodes();) {
 		node =3D e.nextNode();
 		node.collectInto (collectionVector, LinkTag.class);
 }
=20
This will get link nodes at all levels.
