parsing data

how would i go about parsing data off of a webpage with java script?

if it isn't possible then just say so.

or html if that can do it

(like pictures and text)

 

Please be more specific about what you're trying to do.

 

There are only so many ways one can say "parsing data."

I doubt you could do it without a more advanced language like PHP, which unlike JavaScript was made for preprocessing such things. HTML is a markup-language which your browser interprets to display content on a webpage, therefore it certainly can't do what you want, and JavaScript is made for the dynamic display of content (such as rollover menus and whatnot) on a webpage. I'm not sure about JavaScript, but I have an educated guess that you can't.

 

^^ I doubt that he's referring to the "parsing data" that we were thinking of.

It seems like he's asking about pulling images and text out of web pages, but he's not being clear enough with his post.

 

to be more specific, say i dont like that the rs DB is all cluttered and it loads slow. i want to parse only max/lowest price and the pic of the item.

then put this data somewhere els (idc where really)

 

So you want to grab the price on an item basicly and put it on your own site?

 

Requires to be able to pull the entire webpage in to a string, and either split or use RegEx to gather the data. PHP is your best bet, but you need a server with support for PHP to do that.

 

would apache on my computer work or do i NEED a server

 

you just need to install php and it will work fine.

 

If you want the site/script/page/whatever to be publicly released, then you need a server to host the PHP scripts on, yes.

 

I'm actualy developing a program to do just this in ASP Classic/JScript.

You have to learn the HTML ID system Jagex uses in their generation pages, and create a RegXP parser that pulls the info out that way.

Once you have the ItemID, you can pull the images and graphs directly from the server.

See my RS ItemID Viewer in the RS Cheating section for an example.

 

This can be done with cURL and SubString in PHP

 

So you would like to grab the max & lowest price & pic (hotlinking....) and put that on your own site?

 

a faster way would be file_get_contents(); and the use of my favorite function ss_between();

PHP:

function ss_between($string,$start,$end) {
   $string=" ".$string; //The string.
   $startpos=strpos($string,$start); //Find the position of the start string.
   //Check if $startpos equals zero.
   if ($startpos == 0) {
      //If $startpos does equal zero, do this:
      return false; //Return false.
   }
   else {
      //If $startpos doesn't equal zero, do this:
      $startpos+=strlen($start); //Add the string length of $start to $startpos.
      $endpos=strpos($string,$end,$startpos)-$startpos; //Find the string position of $end.
      return substr($string,$startpos,$endpos); //Return the new value.
   }
}
