Question about namespaces?

DJ_AM_Juicebox used Ask the Experts™

I'm trying to use "xlink:href" within an html document, but I'm not sure how to use this. I'm trying to display an <svg> element, here's my code:


      <ellipse cx="100" cy="100" rx="20">
         <animateMotion dur="40s" >
                <mpath xlink:href="#curve"/>   // <-- Problem

yeah so my browser won't load the page, saying:

  XML self-closing tag syntax used on <mpath>. The tag will not be closed.

the <svg> element is originally taken from a .svg file, I want to put it into this .html file. What's the right way to reference it?

Oh it looks like the error is telling me I can't use the shorthand close-tag notation. So this is an error:

  <mpath xlink:href="#curve"/>

but this parses fine:

  <mpath xlink:href="#curve"></mpath>

is there a way to tell the browser to expect the shorter-notation? Otherwise I have to always add these extra tags.

There are some ways to have a SVG appear on a HTML page, but under the current standards+compatibilities I do not think it is possible to just insert a <svg>.....</svg> element inside a html/xhtml webpage.

That being said the current methods are documented on this page > , the last method on the page named "I Wish...." is what we all wish were possible.

For your question about the shorthand notation I really have no ideas about that one sorry.
The SVG spec requires rx and ry attributes for ellipse element. You are missing the ry attribute.
