[Htmlparser-user] Excluding some tags

[Manish K. <ma...@we...>]

This indeed is a newbie question. I could not find a work around to exclude
some tags (<script> in my case) while parsing.

I tried using the NotFilter as underneath, but it didn't work as I got all
the <script> tags in my NodeList -

> NotFilter noScriptFilter = new NotFilter();
> noScriptFilter.setPredicate(new NodeFilter(){
>   public boolean accept(Node currNode){
>     if(currNode instanceof TagNode){
>       if(((TagNode)currNode).getRawTagName().equalsIgnoreCase("script")){
>          return true;
>       }
>     }
>     return false;
>   }
> });
> NodeList allNodes = this.parser.parse(noScriptFilter);
>

Would appreciate if someone can guide me throgh this.

Thanks
Manish

Although the filter is correct, the tag enclosing the <script> tag is
accepted, and with it it's child tags - including the <script> tag.
Maybe a way to do it is to override the ScriptTag class with MyScriptTag so
that it prints nothing in the toHtml () call.
Add the overridden class to the PrototypicalNodeFactory as described here:
http://htmlparser.sourceforge.net/faq.html#composite, and then get all tags
and print the whole thing with System.out.println
(this.parser.parse(null).toHtml
());

Re: [Htmlparser-user] Excluding some tags

[Manish K. <ma...@we...>]

Thanks for the revert Derrick. So, here's the real problem -
I do want to retain the script tag. At the same time, I want to override all
the links in the page. The parser doesn't play nice. Consider the scenario
underneath for an html

<script>
>  document.write("<a href='/jslink'>JS Link</a>")
> </script>
> <a href="/somelink">Some link</a>
>

To me the string literal inside script tag above is not a link at all.
However, when I try to fetch all the <a> using the parser it would give me
both of the above. Is there a way to not get the <a>s which are not in the
<script> tag?

Thanks
Manish

Tgat's not valid HTML. You'll want  to turn strict script scanning off then.
