DevOps, CI/CD and Automation

Another problem:

I have characters such as:
- "<", ">", "&"

in my titles. These I code as:
- &lt; , &gt;, &amp;

As you can see below:
..
<tocitem text="The &lt;helpbook&gt; Tag">
<tocitem text="The &lt;helpbook&gt; Tag" target="Helpbook3N109_htm"/>
<tocitem text="The &lt;cprojstyle&gt; Tag" target="Helpbook3N110_htm"/>

...

However, they then get displayed as &lt; and &gt; rather than converted.
If I instead use <,>, and &, and try to use HelpSetDemo, I get:
..
C:\ohelp\bin>helpsetdemo
