如何为svg提供背景图片？

Question

I have 2 .svg 's:

1. map.svg - https://github.com/djaiss/mapsicon/blob/master/all/ad/vector.svg
2. flag.svg - https://github.com/hjnilsson/country-flags/blob/master/svg/ad.svg

I want to inject the flag.svg as a background-image into the map.svg

What's the way to do it? Is there's an attribute for the svg or a sub element which is right for this kind of task?

Here's my snippet:

Answer 1

Use the image element and reference your SVG file.

<svg>
  <image href="flag.svg"/>
</svg>

then set the map.svg as the background image.
