Get value from XML to ASP variable

In my ASP I request data with XML over HTTP post. The returned result is also in XML. Based on the returned value in my ASP I need to run different functions. However I cant get the value in to an ASP variable.

After I do HTTP Post I do the following:
Response.Write xml.responseText

Which then displays this on the scrren:
<?xml version="1.0" encoding="UTF-8" ?>
- <connector_ret>
- <function name="sql_get_int" id="iEmailExist">
  <ret_val name="rv" type="integer">2076</ret_val>
  </function>
  </connector_ret>

Now I want the integer "2076" that was returned in a variable.

So I can do:

If Myvalue = '' Then
  RUN Function
Else
   Run another function
End If
