I have both purslane and spurge as weeds and I don’t think you’d readily confuse one for the other. Just check the “sap” for one thing. I still probably wouldn’t eat it without someone knowledgeable showing me just in case.
My sister has eaten it and said she didn’t care for it but perhaps there’s some way to prepare it to mask or alter the flavor.
