DOM.getelementsbyTagName help needed!

[Riorin]

I'm trying to extract data from certain web sites that keep all data in Javascript generated tables.

I thought getting the content of each Table or TableCell element by using javascript in address line of a browser could do the trick.

However, I failed at the first obstacle!

After putting

javascript: tbls = document.getElementsByTagName("table"); nmbroftables=tbls.length; alert(nmbroftables)

in address line of a browser I get the message that number of tables is 0 although the page of interest is full of tables and Web Developer add-in for Mozilla cleary recognizes them and can outline them!

The page of interest is

http://www ps-kladionica

hr and you can click on Ponedjeljak (Monday), Utorak (Tuesday) and so on to see offers for that day created dynamically and put into HTML tables!

So what should I do to retrieve that content?

Many thanks!

The website page is framed, there are no tables in the outermost frameset. Hence 0.

The frames are named: container, header, main and bottom.

By the way ... You can get the frame map of any page by running this bookmarklet:

javascript:var%20f1Lt="";var%20ma8i=999;var%20ma9j=999;for(i=0;i<ma8i;i++){if(top.frames[i]){f1Lt+=i+"=,"+top.frames[i].name+"==%20"+top.frames[i].location+":\n";for(j=0;j<ma9j;j++){if(top.frames[i].frames[j]){f1Lt+=i+","+j+"=."+top.frames[i].frames[j].name+"==."+top.frames[i].frames[j].location+";\n";}}}}alert(f1Lt);
