If you use SVG symbols within QGIS you can use params like these so you can adjust properties interactively in QGIS:
fill = param(fill) fill-opacity = param(fill-opacity) stroke = param(outline) stroke-width = param(outline-width) stroke-opacity = param(outline-opacity)
I would like to do the same with text within an SVG-image: Use (text-)placeholders in the SVG and fill in the actual text stored as QGIS variables within the print composer:
Is this already possible?
You can display SVG with HTML like :
<!DOCTYPE html>
<html>
<body>
<svg width="100" height="100">
<circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
</svg>
</body>
</html>

In a print composer, create a text label and check Render as HTML, you can place variables in placeholders :
<svg width="100" height="100">
<circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="[%@color%]" />
</svg>
