How to substitute brackets in the beginning of string in perl?
Hi,
I have a string like this user can specify different query sets that is why "or" is mentioned:
Code:
$string="[[:<:]](";
or
$string="[[:<:]]((";
or
$string="[[:<:]](((";
or
$string="[[:>:]](((((";
What i have to do is substitute these brackets in the beginning.
I tried like this:
Code:
if($string=~/\[\[:<:\]\]\(/)
{
$string=~s/\[\[:<:\]\]\(/\(\[\[:<:\]\]/g;
}
elsif($string=~/[[:<:]]\(\(/)
{
#same here
}
elsif($string=~/[[:<:]]\(\(\(/)
{
#same here
}
elsif($string=~/[[:<:]]\(\(\(\(/)
{
#same here
}
elsif($string=~/[[:<:]]\(\(\(\(\(/)
{
#same here
}
If statement i can use but i will be not be sure how many brackets will be there to substitute in the beginning?
I have to avoid this if loop!!
The output should be like this.
Code:
$string="\([[:<:]]";
or
$string="\(\([[:<:]]";
or
$string="\(\(\([[:<:]]";
etc like this all these different string examples are based on the users query sets that is why i just mentioned or such that user can give either like first string ( [[:<:]]\( ) or like second string ( [[:<:]]\(\( ).
How can i put or substitute brackets in the beginning of the sting?
