[Laszlo-dev] escaped code in live examples

[Lou Iorio]

What is the purpose of the escaped code in live examples?

In the debug chapter (example 50.2) we have this:


<<example role="live-example">
    <title>Runtime exceptions printed once per line</title>
    <programlisting language="lzx">
    <textobject><textdata fileref="programs/debugging-$3.lzx"/></ 
textobject>
    </programlisting>
</example>
<?informalexample role="live-example"><programlisting role="lzx- 
embednew"><filename>debugging-$3.lzx</filename><parameter/><code>
&lt;canvas debug="true" height="150"&gt;
   &lt;handler name="oninit"&gt;&lt;![CDATA[
     for (var i = 0; i &gt; 10; i ++) {
       canvas.width();
     }
   ]]&gt;&lt;/handler&gt;
&lt;/canvas&gt;
</code></programlisting><programlisting>
&lt;canvas debug="true" height="150"&gt;
   &lt;handler name="oninit"&gt;&lt;![CDATA[
     for (var i = 0; i &gt; 10; i ++) {
       canvas.width();
     }
   ]]&gt;&lt;/handler&gt;
&lt;/canvas&gt;
</programlisting><?lzx-edit programs/debugging-$3.lzx></ 
informalexample?>

As far as I can tell, this does exactly the same thing:

<example role="live-example">
    <title>Runtime exceptions printed once per line</title>
    <programlisting language="lzx">
    <textobject><textdata fileref="programs/debugging-$3.lzx"/></ 
textobject>
    </programlisting>
</example>
<?informalexample role="live-example"><programlisting role="lzx- 
embednew"><filename>debugging-$3.lzx</filename><parameter/><code>
</programlisting><?lzx-edit programs/debugging-$3.lzx></ 
informalexample?>
