Moving back one line

[SomeGuy]

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,

<img src=up.gif><br>
<font size=3>Main name</font>

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

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

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

[arcane]

Code: Select all

incr current_index -1

Code: Select all

[expr $current_index - 1]

or just use

Code: Select all

$lines($current_index - 1)

[demond]

Code: Select all

$lines($current_index - 1)

that won't work

here's what I had in mind:

Code: Select all

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

ah yeah, you were talking about lists and not arrays...
my fault.
anyway, i gave him 1 not working solution and 2 working, that's 67% - not too bad
