li in linktag

[srikanth]

Hello ,

I am using linktag to extract data from link elements.I do alright when I get linkText and link information . But in cases where i have a <li> tag enclosing my linkText i cannot extract the link. How would i get the link text when i have li tags?

Thanks

It seems you aren't using a filter, because it would then come for free:

NodeList links = parser.extractAllNodesThatMatch (
  new NodeNameFilter ("A"));

This will put all the <A>xxx</A> tags in the page into the links list.

Hello Derrick,

Thanks for your reply. I couldn't find any NodeNameFilter  class. Anyway here is the code I am using to extract links. Using this code the links which have <li>tags don't show any text. How could i modify this?

Parser lt = new Parser();
                    lt.setInputHTML(answer);
                    NodeFilter linkFilter = new NodeClassFilter (LinkTag.class);
NodeList links = new NodeList ();
                    for (NodeIterator e = nt.elements (); e.hasMoreNodes (); )
                    e.nextNode ().collectInto (links, linkFilter);
for (int i = 0; n=links.size (); i<n;i++)
                    {   
                        LinkTag linkTag = (LinkTag)links.elementAt (i);
                        if(linkTag.isHTTPLikeLink()){
   

                            System.out.println ("link text   "+linkTag.getLinkText());
                            System.out.println (" link tag  "+linkTag.getLink ());
                        }
                    }

thank you

Sorry, it's TagNameFilter, in the filters package.

I can't see why you aren't getting the text. The getLinkText() method is just calling asString() on the getChildren() NodeList, which uses toPlainTextString(). If you can't debug it, perhaps just use:
    linkTag.getChildren ().toHtml ();
If that shows the "<li>text</li>" you expect, then you should log a bug.
