per #1057, use startsWith to optimise the detection of data and svg names

this PR would satisfy two outstanding PRs

Thanks for the PR @iambumblehead and especially for the benchmark which shows that this is in fact an optimization.

The only "downside" to this is that it doesn't work in Internet Explorer. But at this point, I don't think we have to worry about that anymore.
