For example, to make it easier to identify where an issue occurred during document generation, you can specify your own tag value.

Examples

Create Three Levels of Headings

This example shows how to add three levels of headings, each formatted according to its level. This example inserts three heading objects into a document: a Heading1, a Heading2, and a Heading3.

import mlreportgen.dom.*;
d = Document('mydoc','docx');
open(d);

title = append(d, Paragraph('Document Title'));
title.Bold = true;
title.FontSize = '28pt';

h1 = append(d,Heading1('Chapter 1'));
h1.Style = {PageBreakBefore(true)};
p1 = append(d,Paragraph('Hello World'));

h2 = append(d,Heading2('Section 1.1'));
p2 = append(d,Paragraph('Text for this section.'));

h3 = append(d,Heading3('My Subsection 1.1.a'));
p3 = append(d,Paragraph('Text for this subsection'));

close(d);
rptview(d.OutputPath);
