Hi, I have tag, which needs to be sequentially numbered. The text goes like this...

<exm>This is example 1
<exm>This is example 2
<exm>This is example 3
<exm>This is example 4

I need to number the <exm> element sequentially until they are sequential.

<exm num="1">This is example 1
<exm num="2">This is example 2
<exm num="3">This is example 3
<exm num="4">This is example 4

If the same set of elements appear in a different part of the text, the number needs to restart.

The code I wrote to achieve is:

$_ =~ s/<exm>/'<exm num="'.$exmno++.'">'/egs;
if ($_ != /<exm>/g) {$exmno=0}

I have the content stored in $_. I don't know why, but I am not able to get the numbers reset if the line does not encounter a <exm> tag. Can anyone help me out?
