SVG is written in XML.
SVG Example
The following example is an example of a simple SVG file. SVG files must be saved with an .svg extension:
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
xmlns="http://www.w3.org/2000/svg">
stroke-width="2" fill="red"/>
(To view the SVG source, open the example and right-click in the example window. Select "View Source".)
Code explanation:
The first line contains the XML declaration. Notice the standalone attribute! This attribute specifies whether the SVG file "stands alone", or contains a reference to an external file.
standalone="no" means that the SVG document has a reference to an external file - in this case, the DTD.
The second and the third line refer to the external SVG DTD. The DTD is located at "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd". The DTD resides at the W3C and it contains all allowable SVG elements.
The SVG code begins with the
tag closes the root SVG element and the document.
Note: All opening tags must have closing tags!
