The subject line may not correctly describe the problem but that is probably
because I don't really understand the problem myself. Here's a brief
rundown of what I am trying to do:
I have a string that is delimited by pipes ( | )
Within each subset of the string there are one or more other value pairs
Each of those pairs is separated from the others by a semi-colon ( ; )
The name and value in each pair may be split by a colon ( : ) or an
equals sign ( = )
I want to create one array that contains all the data parsed out into
individual pieces
Here is the code:
1) $t =
"content-type:image/gif;name=clip3.gif|content-transfer-encoding:base64|cont
ent-disposition:attachment;filename=clip3.gif|";
2) @tt = split(/\|/,$t); # split the string on the pipe character
3) $counter = 0; # initialize the counter
4) foreach $e(@tt) # loop through each element of the array tt
5) {
6) @tt[$counter] = split(/\;/,$e); # split the value of $e
and re-assign the value of $tt[$counter] to the resulting array
7) foreach $f(0..$#{$tt[$counter]}) # loop through each
element just assigned
8) {
9) print "$f is $tt[$counter][$f]\n"; # print the
index of the current iteration and the value associated with it
10) }
11) $counter++; # increment the counter
12) }
What happens is not what I expected. I expected to get an array that
would look something like this:
$tt[0][0] = "content-type:image.gif"
$tt[0][1] = "name=clip3.gif"
$tt[1][0] = "content-transfer-encoding:base64"
$tt[2][0] = "content-disposition:attachment"
$tt[2][1] = "filename=clip3.gif"
What I seem to end up with a single dimensional array that only contains
the values for the zero indices of the second dimension.
$tt[0] = "content-type:image.gif"
$tt[1] = "content-transfer-encoding:base64"
$tt[2] = "content-disposition:attachment"
Another thing I noticed is that $e gets re-assigned after the execution
line #6. Is $e treated more like a pointer in the context of line #4?
If anyone has any comments or advice, I would appreciate it.
Thanks,
Chris
