jquery - How to place text in the center of an svg path

Question

For rendering SVG I'm using jQuery SVG plugin. And, now I want to add text to each path and polygon. On jsFiddle you can see generated markup by plugin.

For creating text I wrote the following code:

var svgg = $("#rsr").svg('get');
var texts = svgg.createText();
svgg.textpath($("#Layer_x0020_1"),id, texts.string('We go ').
   span('up', { dy: -30, fill: 'red' }).span(',', { dy: 30 }).
   string(' then we go down, then up again'));

In the code on jsFiddle you can see that the textpath tag exists, but it's not visible. How to add text to the center of each path?
Thanks.

To place text in a straight line on top of a shape, in the middle of the boundingbox see:

http://jsfiddle.net/dYuAA/114/

It just adds some javascript to place text.

function addText(p)
{
    var t = document.createElementNS("http://www.w3.org/2000/svg", "text");
    var b = p.getBBox();
    t.setAttribute("transform", "translate(" + (b.x + b.width/2) + " " + (b.y + b.height/2) + ")");
    t.textContent = "a";
    t.setAttribute("fill", "red");
    t.setAttribute("font-size", "14");
    p.parentNode.insertBefore(t, p.nextSibling);
}

var paths = document.querySelectorAll("path");
for (var p in paths)
{
    addText(paths[p])
}

The above only looks at path elements, but you could tweak the selector to include whatever you need.
