Re: [Htmlparser-user] Not all image tags are returned

[Somik R. <so...@ya...>]

Hi Annette,
    Thanks for the report, I wrote a functional testcase, to do a raw =
check IMG tags, and with the parser, and could reproduce the bug. I dont =
think its a problem with the image scanner code - bcos the unit tests =
are passing with the same yahoo tags.
    Here's a quick solution for you : Dont use registerScanners() for =
now. Since your app specifically needs to check only image scanners, =
replace the line :

parser.registerScanners();=20

with
parser.addScanner(new HTMLImageScanner("-i"));=20

    I checked that all the yahoo image tags come fine with this change. =
The functional test has been checked into CVS (FunctionalTests.java), =
and the one with registerScanners() fails. The corresponding unit test =
in HTMLImageScanner passes.

    Meanwhile, I am trying to find out which scanner is messing up..
    Thanks again for your report.

Cheers,
Somik

  Is there any known problem about not all image tags being returned? I =
did the following code:

  =20

                         HTMLParser parser =3D new =
HTMLParser(htmlOriginalFileLoc);

                           // Registering all the common scanners

                           parser.registerScanners();=20

                           for (Enumeration e =3D =
parser.elements();e.hasMoreElements();) {

                              HTMLNode node =3D =
(HTMLNode)e.nextElement();

                              if (node instanceof HTMLImageTag)

                              {

                                   System.out.println();

                                  =
System.out.println(((HTMLImageTag)node).getTagLine());

                                  System.out.println();

                                 =20

                                  =
//imageTagsUrl.addElement(((HTMLImageTag)node).getImageLocation());

                              }

                           }

  =20

  I was testing with another html parser and it found all the image =
tags.  Attached is the source from www.yahoo.com when I ran the code =
above.
