Python: Convert quote in HTML content not HTML tags

Python: Convert quote in HTML content not HTML tags

I have a piece of HTML like this:
<pre class="script">template("main/GlobalShared");</pre>
<pre class="script">
var link = '/Draft/Tracker_1.1';
if (wiki.pageexists(link)) {
&lt;div class="version"&gt; web.link(wiki.uri(link), 'Version 1.1')
&lt;/div&gt;
}
</pre>
I need to convert it like this:
<pre class="script">template(&quot;main/GlobalShared&quot;);</pre>
<pre class="script">
var link = '/Draft/Tracker_1.1';
if (wiki.pageexists(link)) {
&lt;div class=&quot;version&quot;&gt; web.link(wiki.uri(link),
'Version 1.1') &lt;/div&gt;
}
</pre>
I have been fiddling with regular expressions but I can't seem to get even
close. I think my choice is completely wrong.
Can anyone point me in the right direction if this is even possible?
