Whenever I try to use EvaluateXPathExpression, I wind up with a SIGSEGV. I
have done my homework and there is a similar report from 2007, [
http://community.freepascal.org:10000/bboards/message?message_id=242871&forum_id=24082

Are there some examples of its use out there? Googling has not shown any.
I don't mind some other libraries if they are more uptodate. The dates in
the xpath source go back to 2003, but I can't be sure if there have been
some updates over the years.

procedure TutilitiesInterfaceForm.btnTestXPathClick(Sender: TObject);
var
  XML: TXMLDocument;
  pathString: string;
  xpathValue: TXPathVariable;
  strStream: TStringStream;
begin
  strStream := TStringStream.Create(mmoXML.Text);
  ReadXMLFile(XML, strStream);
  pathString := edtXPath.Text;
  //xpathValue := TXPathVariable.Create;
  xpathValue := EvaluateXPathExpression(pathString, XML);
  edtXPathResult.Text := xpathValue.AsText;
end;
