The SVG <tref> element is used to reference text defined by the <defs> element. This way, you can display the same text multiple times in an SVG image without including the <text> element multiple times.
This is an example:
<svg width="100%" height="100%" viewBox="0 0 1000 300" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink="http: <defs> <text id="ReferencedText"> Referenced character data (oldtoolbag.com) </text> </defs> <text x="100" y="100" font-size="45" > Inline character data (oldtoolbag.com) </text> <text x="100" y="200" font-size="45" fill="red"> <tref xlink:href="#ReferencedText"/> </text> <!-- Use the "rect" element to display the outline of the canvas --> <rect x="1" y="1" width="598" height="198" fill="none" stroke-width="2" /></svg>Test and see‹/›
Image effect after running:
Note how the <text> element (inside the <defs> element) has an id attribute. This id attribute value is referenced from the element's xlink:href attribute to the <tref>.
