Hello,

Consider this XML:

?<!DOCTYPE math PUBLIC "-//W3C//DTD MathML 3.0//EN" "http://www.w3.org/TR/MathML3/dtd/mathml3.dtd">
<math xmlns="http://www.w3.org/1998/Math/MathML">
<mi>&pi;</mi>
<mo>&InvisibleTimes;</mo>
<msup>
<mi>r</mi>
<mn>2</mn>
</msup>
</math>

I cannot get the value "&pi;" because TXMLReader.ParseRef as far as I can tell will substitute it with an empty string =(

How can I get "&pi;" or at least the Unicode char for Pi? Maybe I should add a field to allow me to define my own ParseRef routine? This way I could in my own code fix this. I guess I could change ParseRef to substitute &pi; with pi, but this could lead to an endless amount of combinations which could be valid.... and all of them need to be added to ParseRef.

thanks,

The &pi; corresponds to a TDOMEntityReference and NodeName contains the "pi".

  for Node in doc.GetEnumeratorAllChildren do begin
    DbgOut(Space(Node.GetLevel*2+2));
    DbgOut(DbgSName(Node));
    if Node is TDOMText then
      DbgOut(':"',TDOMText(Node).TextContent,'"')
    else
      DbgOut(':',Node.NodeName);
    debugln;
  end;

aha, thanks, it works like that.
