That would be a solution for this problem. My previous comments on the
minimalistic approach of the implementation suggest a different approach:
scan the source string once and replace html entities as you find them (with
a look up table for example). This would scale much better when implementing
iso-8859-1 or '#entity-number;' unescaping .
For every html entity you need a dictionary, and that's makes your program
with more fat.
converting number entity can be done, but you need to know what is the code
page you wish to convert from/to.

You should not unescape recursively.
Input to EscapeHTML: 'lt;' Output: 'amp;lt;' : Correct
UnescapeHTML: input 'amp;lt;' Output '' Wrong.
This is because you replace 'amp;' with '' resulting in 'lt;' which is
translated to ' ' in the next line.
So you suggest to place the amp; translation last.

Un/escapeHTML parsing must be in one go, specially the amp one. Test
against:
amp;lt;
I'm not sure what you mean here.
If you have already html entities you should not escape them. If you do
not have html entities you should escape them.
The Escaping and unescaping works well, I already tested them before I
sent them.
Right unescape lt;, your code .
