Validating xml SpecBind

I have a link which gives me an xml format output in the web browser. I want to ensure that the data is accurate to what i believe I will see. I am using specbind to conduct the validity tests, and I want to make sure that I will be able to see if the result contains the data I believe.

The data contains various information which remains static as well as a current data/time. This will be what I am going to run my validity tests against. Below is the currents step which I have written:

Then I see
| Field | Contains     |
|       | "IP Address" |
|       |              |

Currently I don't know what these fields will be called as it only gives me the result text. I also would like to know how I can put the current date time in the contains field.

Thanks for your help
