Removing commas from string

I have a string like this

<place xpos=74 ypos=86>,<place xpos=135 ypos=159>,<place xpos=236 ypos=214>,<place xpos=264 ypos=137>

and I want to make it like this

<place xpos=74 ypos=86><place xpos=135 ypos=159><place xpos=236 ypos=214><place xpos=264 ypos=137>

How to do it? Can you help me.

Thanks in advance.
