I can't get the children from the svg fragment pre-entered in the string.
Need return content <g> element from source string;
Example:
has dom:
<svg>
<g class="parent"> <rect ... /> </g>
<svg>
let strNewContent = '<g class="draggable-group" data-id-device="Light-X[room-1549613406671][0]"> <rect height="75" width="184" x="8" y="0" fill="#DDD" rx="6" ry="6" /> </g>'; // created svg string using handlebars.js
// need replace old content in new content
// need extrude `<rect ... /> & etc...` from string and put (innerSVG)
$('.parent').html($(strNewContent).html()) // I understand it won't work. (It's just to understand what I mean.)
d3.select(svgElem).html(d3.select(svgElem).html()); // костыль для обновления svg документа
ps:Thank you for your patience and understanding for my English
need extrude <rect ... /> & etc... from string and put (innerSVG)
I understand that this can be done in 2 ways (as I can see): by a regular expression, cut the content or convert it to a fragment and try to squeeze out the content and add it to a new element as content (helped by #altocumulus). But I really already tried, many times to convert to a fragment and to squeeze out contents, nothing turns out (only now came to the decision, with a regular expression)(now I will experiment).
ps: What's best to correct (title) the issue for everyone to deal with this problem to solve it?

I'd like to use MathJax to write various equations that include SVG shapes along the lines of the following:
(2 * [red box]) + [red box] = [three red boxes]
Where each item in brackets would be a custom SVG element defined in the HTML ranging from simple (a single box) to more complex (multiple shapes). The reason for needing this is that I want to use MathJax's ability to format math equations while replacing some symbols with SVG shapes. I may need to specify other HTML as well.
I suspect this can be achieved by using MathJax's HTML snippets but I don't know how to take the sample code they provide and make it work for any given equation.
Any help would be greatly appreciated.
If you are using MathML input, you can use the <mglyph> element to include an svg image into your expression, as in:
<math>
<mglyph src="dice.svg" height="42px" width="42px" valign="-14px" alt="Dice showing five dots"></mglyph>
</math>
or even
<math>
<mglyph src='data:image/svg+xml,
<svg xmlns="http://www.w3.org/2000/svg" height="42px" width="42px">
<rect stroke="black" fill="none" x="1px" y="1px" stroke-width="2px" rx="5px" width="40px" height="40px"></rect>
<circle stroke="black" fill="black" cy="30px" cx="30px" r="5px"></circle>
<circle stroke="black" fill="black" cy="30px" cx="10px" r="5px"></circle>
<circle stroke="black" fill="black" cy="20px" cx="20px" r="5px"></circle>
<circle stroke="black" fill="black" cy="10px" cx="30px" r="5px"></circle>
<circle stroke="black" fill="black" cy="10px" cx="10px" r="5px"></circle>
</svg>'
valign="-14px"
alt="Dice showing five dots">
</mglyph>
</math>
If you are using TeX input, you can create the mglyph using the \mmlToken macro:
\mmlToken{mglyph}[src="dice.svg" width="42px" height="42px" valign="-14px" alt="Dice showing five dots"]{}
You can also use the "img" extension from the third-party extension library. This defines an \img macro that makes loading the image a bit easier:
\img[-14px][42px][42px]{dice.svg}
I think you should be able to do what you want using one of those.
(This is my response to the cross-post on the MathJax User's Forum)
I would like to do "complex" animation with gsap and svgs.
but I don't know what is the best approach to this.
it is better to create and to import an unique svg with all the elements or maybe it is better 4 different svgs?
I have 4 different characters: a tree, a lamp, a desk and a man.
basically my animation is move the objects on the x, and appearing and to disappearing stuff.
If the elements of the animation are part of one complex animation, you can use one single SVG for this.
To control the DOM of the SVG via CSS and JavaScript you need to add the SVG directly inline into your HTML page. Not embed via img tag or object tag or similar.
<body>
<h1>My SVG Animation</h1>
<svg width="100" height="100" viewBox="0 0 300 100">
<circle class="animation-element-01" cx="50" cy="50" r="40"/>
<rect class="animation-element-01" x="150" y="20" width="150" height="150"/>
<!-- etc -->
</svg>
</body>
Another advantage of this method is, that there is no additional html requests.
Plus the whole animation can be made responsive via the viewBox.
The idea is pretty simple:
I have an SVG path and an Rect,
I need to make the path carve through the Rect, the resulting "hole" should be see-through.
Here's jsfiddle with a copy of how it's looking right now:

</div>
Here's an image of what it would probably look like if we can carve that hole:
http://i.stack.imgur.com/5fjBR.png
The Path is dynamically generated and can be quite complex, so I can't really eyeball the result.
It has to be done in javascript (or with some very clever usage of styles).
I need the result to be a DOM node that I can eventually move between z-indexes (could be grouped? a resulting "difference" path calculated in js?).
Performance and experimental features are not an issue, this is aimed at nwjs app.
Some other notes:
I'm already using jQuery, svg.js and a bunch of other libraries, so adding
new libraries is not a problem.
The rect could also be replaced by just a color filled div, if that helps solve the problem.
Ive already tried masks and clips but couldnt come to a working solution.
Any help appreciated, Thank you in advance.
A mask is what you need. I'm not sure what you tried before, but it should do what you want.
Just create a mask like so:
<defs>
<mask id="theMask">
<rect width="100%" height="100%" fill="white"/>
<path id="thePath" d="..." fill="#000000"></path>
</mask>
</defs>
Either move the original path into the mask, or copy it and hide the original.
Then apply the mask to the rect
#theRect {
mask: url(#theMask);
}

I'm trying to create an SVG-based menu. I'm completely new to SVG, and have been searching for 1.5 days for a simple example of interaction between JS and SVG. My document structure is:
/LOCAL_FOLDER (not on a server yet)
+index.html
/CSS
+global.css
/JS
+navigation.js
/IMAGES
+navigation.svg
I have a simple html body
<body>
<div id="outer-container">
<div id="navigation-container" onclick="javascript:changeColor();" >
<object id="navigation" type="image/svg+xml" data="images/test.svg" >Your browser does not support SVG</object>
</div>
</div>
</body>
My SVG looks like this (for now)
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<circle id="test" cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/>
</svg>
This is the general structure I want to use. As you can see, it has JS from the html head (linked) interacting with my SVG #test. For now, I'd deal with having it change opacity on load just so I can start figuring out HOW to interact.
I've tried JQuerySVG, Raphael, straight JS, JS within SVG, etc, and I can't seem to connect. What I'm looking for (and can't seem to find an operational snippet of) is a super basic example that I can then learn from...
From what I've tried, I rarely had success using data="", however using something like container.load(your.svg), I could then modify to my hearts content.
another issue is to make sure that the svg data was standard.
from there (I used jQuery) jQuery('#test').attr('style','stroke:#ff0000') should change the stroke to red.
I would like to know if there is a way to get a better rendering of svg rotated text?
<?xml version="1.0" encoding="UTF-8"?>
<svg version="1.1" width="900" height="400" xmlns="http://www.w3.org/2000/svg">
<text x="50" y="50" id="text_0" transform="rotate(17, 50, 50)">
SVG text test
</text>
</svg>
You can test the render of this code here: http://jsfiddle.net/vbzTd/2/
It seems like characters are not following the baseline and I don't understand why.
Thanks a lot for your help.
I had similar problem. When the text is rotated all the letters twitching. And it happens in all browsers. Fortunately, I had not so many text for rotating and I just converted text to path. After that it works perfectly. But if you have to rotate a lot of text - size of svg will increase dramatically.
