All,

I am writing a conversion program and in that, I want to convert all the <s1> to <section1> except if they are appearing within <sb>...</sb>. The text I need to convert will look like follows: 

<s1>King of England
JAMES, by the Grace of God, King of England, Scotland, France and Irel
+and, Defender of the Faith...
...
This first selection was written in England to establish the colony of
+ Virginia
<sb><s1>Rights of Landowners
We, greatly commending, and graciously accepting of, their Desires for
+ the Furtherance</sb>

The first <s1> should be converted to <section1>. This is not a problem. But the second <s1>, because it is appearing inside <sb>...</sb>, it needs to be tagged as <h1>.

I used the following code to do this. 

$_ =~ s/<s1>/<section1>/g;
if ($_ =~ /<sb>/)
{
   while($_ =~ /<\/sb>/)
   {
      $_ =~ s/<s1>/<h1>/g;
   }
}

There is something incorrect in the usage of while statement. Can someone help me on this?
