Hi,  
I’m going to communicate with a medical device with TCP/IP using a UR3e, and will recieve the response in:

_ **"XML fragments sent using the ASCII character set. A command consists** _  
_ **of a “command” element followed by a name attribute and one or more parameter attributes:** _

Example:  
\<response command=“AssumeControl” code=“0” message=“Success” /\>

I assume I should use **socket\_read\_ascii\_float();** to recieve the data. I then want to read the “0” to find out if the command was successful. How do I handle the data read in the UR program?

You’ll probably have to use **socket\_read\_string**

read ascii float requires data to be formatted a specific way:

You’ll probably have to use the URScript string parsing functions to seperate out your value. Some combinations of these should do it:
