How to enable animation in svg when embeded in ppt

I have embeded an svg in ppt, svg is in XML format only i.e. no javascript but has animation in it using animate tags
But when i inserted it in ppt animations are not displyed
I inserted svg to a ppt using control box ->Tools-> svg document, as insert object was not working. But animations are not shown while running the slide show

In fact some times it shows the animation i guess sometimes when we run the slideshow for the first time but it not the case always .

How do i make the animation to be run every time

<text startOffset="0" text-anchor="start" fill="black">
8
<animate restart="always" calcMode="linear" dditive="replace" accumulate="none" fill="freeze" begin="5s" dur="5s" to="225" from="365" attributeName="x"/>

<animate restart="always" calcMode="linear" additive="replace" accumulate="none" fill="freeze" begin="5s" dur="5s" to="100" from="50" attributeName="y"/>
</text>

the animate tags are like this in the svg

please help me

I think that your problem come from timeline in PowerPoint.

Try to add in main svg :
onload="evt.target.ownerDocument.rootElement.setCurrentTim e(0)"

or to begin animation by script using beginElement() and with begin="indefinite" in animate element.
