Hi Monks,

I have an HTML text file in this kind of format:

<html>
...etc...
<pre>
Line 1
Line 2
...etc...
Line n
</pre>
...etc...
</html>

[download]

I'd like to put a <p> tag at the end of each line which appears between the <pre> & </pre> tags, and finally remove the <pre> & </pre> tags, to give me this: 

<html>
...etc...
Line 1<p>
Line 2<p>
...etc...<p>
Line n<p>
...etc...
</html>

[download]

I guess the simple and efficient way to do that would be to process the file line-by-line (and I might end up using such code), but first I'd like to see how it could be done treating the whole file as a single line. Here's the code I tried: 

perl -0 -pe '1 while (s/(<pre>\n.*?)\n(.*<\/pre>)/$1<p>$2/ms);s/<\/?pr
+e>//g' htmlfile

[download]
That works, except it strips the \n chars out like this of course: 
<html>
...etc...
<pre>
Line 1<p>Line 2<p>...etc...<p>Line n<p></pre>
...etc...
</html>

[download]

So I tried this: 

perl -0 -pe '1 while (s/(<pre>\n.*?)\n(.*<\/pre>)/$1<p>\n$2/ms);s/<\/?
+pre>//g' htmlfile

[download]
But that loops infintely because it keeps on matching "Line 1", which becomes "Line 1<p><p><p>...".

How can I concisely write such code, processing htmlfile as a single line?

Thanks...Terry
