+=head2 Loltree Functions
+
+A loltree is an arrayref consisting of arrayrefs which is used by 
+C<< new_from__lol >> in L<HTML::Element> to produce HTML trees.
+The CPAN distro L<XML::Element::Tolol> creates such XML trees by parsing XML files,
+analagous to L<XML::Toolkit>. The purpose of the functions in this section is to allow 
+you manipulate a loltree programmatically. 
 
-=item * L<HTML::Tree>
+These could not be methods because if you bless a loltree, then HTML::Tree will barf.
 
-A perl package for creating and manipulating HTML trees
+=head3 HTML::Element::replace_node($lol, $node_label, $new_node)
 
-=item * L<HTML::ElementTable>
+Given this initial loltree:
+
+    my $initial_lol = [ note => [ shopping => [ item => 'sample' ] ] ];
+
+This code:
+
+    sub shopping_items {
+      my @shopping_items = map { [ item => _ ] } qw(bread butter beans) ;
+      \@shopping_items;
+    }
+
+    my $new_lol = HTML::Element::newnode($initial_lol, item => shopping_items());
+
+ will replace the single sample with a list of shopping items:
+
+
+     [
+          'note',
+          [
+            'shopping',
+            [
+              [
+                'item',
+                'bread'
+              ],
+              [
+                'item',
+                'butter'
+              ],
+              [
+                'item',
+                'beans'
+              ]
