in thread Using HTML::Parser extract text from tables

You might want to add an initialization of @save as well, to avoid trying to der eference an undefined value when you leave a toplevel table. Something like this perhaps:

Actually since @save is only being accesed on an end tag that means a begin tag was involved which pushed a value on save. In case of the first table the values 0,0 will pushed on the save and then poped when that table ends. So I dont think I need to wory about dereferncing an undefined value.

I dont think pushing $tablenr will fix the problem, because when the old value is poped it will think on the next table it should $tablenr++ which will ovewrite the previous data. Have to do something else.

    You are right about that @save and undefined values thing. My brain must have fallen asleep there for a while.

    Pushing tablenr will fix the recursive table though. You still increase $count each time you encounter a table start. You also set $tablenr to $count. Its only on table end that you restore $tablenr, but you do _not_ restore $count. Hence, each table is given a unique, increasing number.

    Have you tried it btw? I haven't. so I'm only speaking theoretically here....
