svg-sprite: symbol conversion to single svg icon


I have a svg sprite like the following:

<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg" style="width:0;height:0;visibility:hidden;">
    <symbol viewBox="0 0 500 500" id="test-icon"><title>test</title><ellipse class="background" id="test-background" fill="#fff" cx="248.8" cy="251.4" rx="246.2" ry="244.8"/>

    </symbol>
</svg>

Now my question is: can I just make a svg out of the symbol, just by extracting the symbol and then replacing the symbol-tag with an svg-tag? Or how can I achieve this conversion to separate svg?

I thought of a little script, that can inject several svg icons from an svg-sprite like above, so the icons can be style by css better/individually.

The thing here is that in the sprite there are symbols, which (as far as I read) can only be used with <use xlink:href>. But then the icon can't be styled individually like inline svg could be (as it is a clone).

Edit: I found open-iconic svgIncetor that uses an img-src and single svgs to inject into the html. Also to mention is that I alread read following articles by Chris Coyier:

Basically I want to combine the technics used there to have an icon system, that can have multi-color icons based on css and icon-sprite (with inline svg through js-inject). The open-iconic injector can only inject sinlge svgs and not from sprites afaik.


Solution

  • There isn't a lot you need to change (see http://jsfiddle.net/yo8bhxfu/):

    You might be on the safe side if you additionally remove the class attributes, the id attributes and the title.

    <svg xmlns="http://www.w3.org/2000/svg" style="width:500px; height:500px;">
        <g viewBox="0 0 500 500" id="test-icon">
            <title>test</title>
            <ellipse class="background" id="test-background" fill="#fff" cx="248.8" cy="251.4" rx="246.2" ry="244.8"/>
