The 1st and 3rd questions are along the same lines, but have slightly
different solutions.
Question 1 is "How do I show an automatic counter in a text-like cell?"
Question 3 is "How do I show an automatic counter in a input-like (i.e.
StandardForm) cell?"
Because different mechanisms are used for the 2 kinds of cells, the
solution is slightly different. First, get the notebook as a NotebookObject
or Notebook expression. A simple way to do this is to extract the
NotebookObject out of the list of open nbs.
In[1]:=
nb=Notebooks[][[2]]
For input-like cells the default counter value is used when generating
GIFs. We need a way to tell the fe to change the default for the counter.
In[2]:=
setnumeq[num_] :=
SetOptions[$FrontEnd, CounterAssignments->{{"NumberedEquation",num}}]
Then, we can use "MarkupRules" to specify what to wrap around each cell.
For text-like cells, we insert the number. For input-like cells, we reset
the counter at each cell. Note, :> is used to make the counter increment
each time the rule is used (-> will only increment the first time it's
used). Finally, we reset the default counters so that the numbering is
correct in the fe.
In[3]:=
section1counter=1;
numeqcounter=0;
Export["file.html",nb,
ConversionOptions->{"MarkupRules"->{
"Section1":>{"<h2>"<>ToString[section1counter++]<>"."</h2>"},
"NumberedEquation":>{setnumeq[numeqcounter++];"<p>", "</p>"}
}}];
SetOptions[$FrontEnd, CounterAssignments->{}]
For Question 2, there are several ways to represent typesetting in HTML.
This is done through the "MathOutput" ConversionOption. The default is
"GIF" which uses graphics. If you want text in your HTML, you can try
InputForm and DisplayForm. But since HTML is very limited in it's
typesetting, these may not be what you want. There is also "MathML", which
uses an XML syntax to represent typesetting. MathML is gaining acceptance
as the standard for representing math on the web and support for it is
growing rapidly.
