[Htmlparser-user] Re: HTML TABLE PARSER

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

Hi Rohit,
    For including your own scanner type, you would need to do something like
this :
[1] HTMLTableTag - the tag that stores the data of the table tags
[2] HTMLTableScanner - the class which does the scanning -
implement the two template methods :
(i) evaluate() - returns true if the tag name is "TABLE". false otherwise
(ii) scan() - returns the HTMLTableTag object from the available text data.
Here, you will be having the tag contents, and you will need to extract the
relevant data out, construct the table object appropriately and return it.

Finally, you need to register this scanner. Thats it - after this, table
object will be identified. All the scanners in the library were written with
this architecture in mind. Check out the entire scanners package, in
particular, HTMLLinkScanner. Check out the corresponding test cases (in
scannersTests package), and you should get a clear idea of the usage.

Also - could you subscribe to the HTMLParser User's list, and mail your
queries to that single mail id.

Cheers
Somik
