How to find wsdl version - web-services

Question

Can any one please suggest how can I find wsdl version my web service is exposing -
snippet from wsdl -
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata"
xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex"

xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing"
name="XXXService" targetNamespace="http://tempuri.org/">
I have gone through these web links -
https://coderanch.com/t/502335/certification/determine-wsdl-version
according to above post it's 1.2
whereas looking at this -
https://www.soapui.org/docs/soap-and-wsdl/working-with-wsdls/
SoapUI documentation says "SoapUI supports 1.1 version of the WSDL specification".
Because my wsdl loads successfully in SoapUI - could it be version 1.1?
So, I am not sure which version of wsdl (1.1/1.2/2.0) my web service is exposing.
Any suggestions please.

There are two WSDL versions: 1.1 and 2.0. A history of how these versions got to be can be found on the Wikipedia page for WSDL.
Also on that page it's a useful image of the differences between them and how to recognize the version you are dealing with:
The easiest way is to look at the root element in the XML:
if it's called <definitions> then it's a WSDL 1.1;
if it's called <description> then it's a WSDL 2.0;
Most of the WSDLs you will find out there will be version 1.1, but if the technology is newer, it might also be possible to retrieve a WSDL 2.0. See for example the answer on this post for more details about some conventions of retrieving a SOAP web service's WSDL if it provides one.
