[Htmlparser-user] Parser once, and filter more tags

[丛林 <con...@gm...>]

Hi, I am a freshman in htmlparser area.

My problem is:
If I want to filter many tags, how can I complete it during one parser
with out reset this parser?

For example:
NodeFilter A = new TagNameFilter("A");
NodeList a = new NodeList();

NodeFilter B = new TagNameFilter("B");
NodeList b = new NodeList();

Now, I have to fetch a and b with parser during two times:

a = Parser.parser(A);
Parser.reset();
b = Parser.parser(B);

Can I complete these once?
[a, b] = Parser.parser(A, B);
As you know, another Parser will consume more resourse.


Thanks for your help :-)

Best Wishes,

-LIn

Depending on what you want to do with the nodes, you should be able to get
both in one pass with an OR filter:

NodeFilter x = new OrFilter (A, B);

This will give one list with both node types and you'll have to handle that
in the subsequent processing.

Dear Oswald,

As you say, if we use OrFilter, the filtered result is mixed with many
node types.

I think the subsequent processing is more complex and more fallible,
such as regex, matching and so on

Is there any Function as,

nodelist[] {NA, NB} = FUNCTION(Filter[] {FA, FB})

or is there any easy subsequent processing?

Best Wishes,
