ah yeah, you were talking about lists and not arrays...

Code:

$lines($current_index - 1)

that won't work

here's what I had in mind:

Code:

set status [lindex $lines [expr [lsearch $lines "*Main name*"] - 1]]

incr current_index -1

Code:

[expr $current_index - 1]

or just use

Code:

$lines($current_index - 1)

Can you just post an example on how I would use index to dynamically choose lines?

read the webpage line by line in a list; then you can access any line by index

I'm trying to parse a webpage, and basically the main name is on the second line, while the status is on the previous line.

Now my script parses the webpage, finds the main name, but now i need to move up one line to catch the status.

ie,

Main name

Now, my script allows for adding and deleting of different names, so it needs to do this in the while loop, now, I'm pretty sure I can handle everything except this one part, never done anything like this before.

Thanks
