Need help on split-function

[Arjen]

Hi All,

What I want to is using a string as PATTERN in a split function. This makes
it possible for me to change the PATTERN on one place in my script...

For example:
$separator = ";";
$line = "field1;value1";
local($field, $value) = split(/$separator/, $line);

How can I make this work ?

In what sense exactly does that not work?

I dont know why this will fail. But you can also quote the
meta-characters in your PATTERN using \Q and \E if they have any.

$separator = "++";
$line = "field1++value1";
local($field, $value) = split(/\Q$separator\E/, $line);

Hi Matthew,

You are right. I will give an example:

Code:
$line = "field1|value1";
$separator = "|";
local($field, $value) = split(/$separator/, $line);

Gives back:
$field = f
$value= v

Code:
$line = "field1^value1";
$separator = "^";
local($field, $value) = split(/$separator/, $line);

Gives back:
$field = field1^value1
$value=

Code:
$line = "field1;value1";
$separator = ";";
local($field, $value) = split(/$separator/, $line);

Gives back:
$field = field1
$value= value1

The last example is working right. The others are not. Even not when i'm
using "\|" instead of "|" for the seperator.

You won't believe it but a namesake of yours just posted exactly the same
question in CLP where I just happened to answer it.
You may want to check there.

And you also may want to read the nettiquette why multiposting will put you
on the fast path into many killfiles.

I'm really sorry, I didn't know that I should not post this message in more
then one newsgroup. Or is it because comp.lang.perl and comp.lang.perl.misc
are related that I shouldn't post in both ?!

Comp.lang.perl is extinct. It doesn't exist except on
misconfigured servers. You should never ever post
to it.

Cross-posting is OK, but in moderation and only
with very good cause. Multi-posting is a definite
no-no.

Having a regular posting on comp.lang.perl to warn people that it
doesn't really exist (and with an authoritative link to the original
control message which should have rmgroup-ed it) would seem to be a
self-contradictory thing to do, but I'm not sure how else the message
is ever going to get out. :-{
