问题
I can't succeed in build an svg with angularjs when tspan are load from ng-bind-html attribute, Firefox and IE do not display them.
My controler look like that :
$scope.titlenotok="svg not ok";
var content = '<tspan dy="20" x="0" xml:space="preserve">line1 not ok</tspan><tspan dy="30" x="0" xml:space="preserve">line 2 not ok</tspan>'
$scope.notok = $sce.trustAsHtml(content);
I create a fiddle to illustrate
http://jsfiddle.net/3WNhT/
For chrome it's OK.

Robert was right.
Here is my solution. The secret was to use createElementNS. so that, The browser understand that it is a svg element and not a html element.
Here is the directive
app.directive('multilinesvgtext', function () {
var xmlns = "http://www.w3.org/2000/svg";
var myLink = function (scope, elem, attrs) {
attrs.$observe('contenu', function (val) {
var data = val;
var generateTSpan = function (lineOftext) {
var tspanElement = document.createElementNS(xmlns, 'tspan');
tspanElement.setAttribute('x', attrs.x);
tspanElement.setAttribute('dy', attrs.dy);
tspanElement.setAttribute('class', attrs.class);
tspanElement.setAttribute('xml:space', 'preserve');
var tspanContent = document.createTextNode(lineOftext);
tspanElement.appendChild(tspanContent);
return tspanElement;
};
// We delete the old children
while (elem[0].firstChild) {
elem[0].removeChild(elem[0].firstChild);
}
var lines = data.split('\n');
for(var i= 0; i < lines.length; i++)
{
var textContent = lines[i]!=='' ? lines[i] : ' ';
var newTspanElement = generateTSpan(textContent);
elem[0].appendChild(newTspanElement);
}
});
};
return {
restrict: 'A',
link: myLink
};
}
);
Which can be uses like that :
<text multilinesvgtext x="30" y="168" fill="#FFFFFF" data-dy="13" class="myclass" data-contenu="{{mydata}}"></text>
My directive add tspan children for each line of text in mydata and use data-dy attribute as dy attribute for this tspan.
