Constructor Detail

LinkTag

public LinkTag(org.htmlparser.tags.data.TagData tagData,
               org.htmlparser.tags.data.CompositeTagData compositeTagData,
               org.htmlparser.tags.data.LinkData linkData)

Constructor creates an HTMLLinkNode object, which basically stores the location where the link points to, and the text it contains.

In order to get the contents of the link tag, use the method linkData(), which returns an enumeration of nodes encapsulated within the link.

The following code will get all the images inside a link tag.

 Node node;
 ImageTag imageTag;
 for (Enumeration e = linkTag.linkData(); e.hasMoreElements();) {
 	node = (Node) e.nextElement();
 	if (node instanceof ImageTag) {
 		imageTag = (ImageTag) node;
 		// Process imageTag
 	}
 }
 

There is another mechanism available that allows for uniform extraction of images. You could do this to get all images from a web page :

 Node node;
 Vector imageCollectionVector = new Vector();
 for (NodeIterator e = parser.elements(); e.hasMoreNode();) {
 	node = e.nextHTMLNode();
 	node.collectInto(imageCollectionVector, ImageTag.IMAGE_FILTER);
 }
 

The link tag processes all its contents in collectInto().
