choose by position ???????????

Hi, can anybody tell me if it is possible to have the choose by position change to a different position each time it occurs in a loop and if so how it is done? I am trying to make a facebook friend adder, many thanks in advance, Cheryl

Yes. You should be able to use a variable or other node as the position, not only a hard-coded number.

 

I just tested the following code snippet and it worked just fine.

Thank you for your time Jim, much appreciated, unfortunately I dont understand what any of it means, my ignorance is astounding but I am very grateful that you tried to help me, Cheryl.

here's some comments for that code snippet to explain what I did a little better:

set				// this initializes the #i variable to zero
 #i
 0

/ loop
|
|+ 10				// loop ten times
|
|+ inc				// increment #i. this adds +1 to #i
|  #i
|
|+ choose by position		// choose the #i'th <p> tag
|  P				// so, if #i = 1, get the 1st p tag
|  #i				// if #i = 2, get the 2nd, and so on...
|
|+ change chosen attribute	// this just changes the text of each <p> tag
|  innertext			// to 'lol #i' just so I could test that it was
|  lol {1}			// in fact choosing them properly. you can do 
|    #i				// whatever chosen commands you want to do
|
\ end of loop
