Create Internal Links

To link from one location in a document to another location in the same document:

For example, you can include an About the Author link to a heading with the title Author's Biography.

import mlreportgen.dom.*
import mlreportgen.utils.*
d = Document('mydoc','pdf');

% Append a link target to a heading
h = Heading(1,'Author''s Biography');
h.Style = {PageBreakBefore(true)};
linkID = normalizeLinkID('bio');
append(h,LinkTarget(linkID));

% Link to the target
append(d,InternalLink(linkID,'About the Author'));

% Append the heading 
append(d,h);

close(d);
rptview(d);

Create External Links

Use an mlreportgen.dom.ExternalLink object to create an external link, specifying the link target and the link text.

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

append(d,ExternalLink('https://www.mathworks.com/','MathWorks'));

close(d);
rptview('mydoc','html');

Add Text or Images to Links

To add text or an image to an ExternalLink or InternalLink object, use the append method with that object. Append a Text, Image, or CustomElement object.

Create Page References

You can create a numeric reference to the page where a link target resides. For example, you can create a page reference in the form “See page 15,” where the target you are referencing is on an object on page 15. For example:

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

% Add target to heading object and append heading and 
% para text to document
h = Heading1(LinkTarget('mytarget'));
append(h,'Referenced Head');
p = Paragraph('Here is some paragraph text.');
append(d,h);
append(d,p);

% Add another page and insert the page reference 
% to the target
p1 = Paragraph('The following paragraph contains the page reference.');
p1.Style = {PageBreakBefore(true)};
p2 = Paragraph('See Page ');
p2.WhiteSpace = 'preserve';
ref = PageRef('mytarget');
append(p2,ref);
append(p2,'.');
append(d,p1);
append(d,p2);

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

In your PDF template, you can use a <pageref> element to create this kind of reference. Your DOM API program must set the link target that the element uses. The <pageref> uses one argument: <pageref target="nameoftarget">.
