Hi,

I am trying to do the following find and replace 

input:
<it>a</it>+2<it>b</it><inf><it>cd</it></inf>
<it>a</it>+2<it>b</it><sup><it>cd</it></sup>

output:
<it>a</it>+2<it>b<inf>cd</inf></it>
<it>a</it>+2<it>b<sup>cd</sup></it>

[download]
this line of code works fine and does the job 
s!</it><inf><it>(.*?)</it></inf>!<inf>$1</inf></it>!g;
s!</it><sup><it>(.*?)</it></sup>!<sup>$1</sup></it>!g;

[download]
but i want to make it dynamic so i changed it as follows and this way it is not working 
s!</it><(.*?)><it>(.*?)</it></$1>!<$1>$2</$1></it>!g;

[download]
please let me know whether i can use $1 in find string and if yes how to use it

In reply to using $1 as find string by texuser74
