It doesn't work, but I'm trying to learn:
JS
function doGet() {
return createHtmlOutputFromFile('KI_SVG_Test');
getContent()
}
HTML
<!DOCTYPE html>
<html>
<head>
<!--1-->
<!--2-->
<!--3-->
<svg class="icon icon-E000-uldf-f"><use xlink:href="#icon-E000-uldf-f"></use></svg>
</head>
<body>
<symbol id="icon-E000-uldf-f" viewBox="0 0 32 32">
