My restroom floor looked wet, I took off toilet and found the floor flange(metal) is rotten,
Tried to take it off for replace. I took out 2 and 2 screws on the flange, but still it is hanging with the plastic soil pipe, can't take apart flange from pipe. How can I?

White plastic pipe? That would be PVC and normally the flange is glue welded in place. However, that would be a PVC flange too but you say you have metal, right? You have to cut it out. Those screws were the mounting screws that held it to the floor and probably the bolts for the toilet. If you use a Dremel saw and cut from the inside you can insert an Oatey ywist-n-set or similar replacement flange.

Hi Gewjoe:

As Ballengerb1 stated, you have to cut the remaining metal off from the plastic pipe/fitting.

You could use a dremel tool to cut the metal or use a pair of aviation (TIN) snips... see picture.

Then use a repair flange to salvage the old fitting/flange and you should be all set... see picture and click on clam2pdf. Here, this repair flange inserts into the groove around the old flange/pipe and basically makes it like a new flange.

The clamshell flange is usually only found at a local plumbing supply house.

Let us know if need more...
