Dear Peter Otten,
Incidentally, you have discovered a fault in that there is an erroneous
difference in my code of 'ecologicalpyramid.html' and that given in the text,
in the first few lines re:
----------------------------------------------------------------------------
<html>
<body>
<div class="ecopyramid">
<ul id= "producers">
<li class="producers">
<li class="producerlist">
<div class="name">plants</div>
<div class="number">100000</div>
</li>
<li class="producerlist">
<div class="name">algae</div>
<div class="number">100000</div>
</li>
</ul>
----------------------------------------------------------------------------
<html>
<body>
<div class="ecopyramid">
<ul id= "producers">
<li class="producerlist">
<div class="name">plants</div>
<div class="number">100000</div>
</li>
<li class="producerlist">
<div class="name">algae</div>
<div class="number">100000</div>
</li>
</ul>
----------------------------------------------------------------------------
I have removed the line <li class="producers"> to the right html code of the
lower
version. Now there is a string ("plants") between the <"li class producerlist">
and </li>
Sorry about that.
However as you said, the input code as quoted in the text, still won't return
'plants'
