How to ignore a part of request

I have mock-server for SOAP in Postman and my service, which send POST requests(text/xml) and get responses(text/xml) from this server. Also I have a Collection with requests for this server. Each request have a lot of examples. I activate “x-mock-match-request-body” header with “true” value.

And when my service send request for mock-server, mock-server matching request from my service and request from my example to give me mock response. But request from my service contains a tag with datetime.

And it’s a trouble, because I need to mock a response, but every time datetime is different. And I want to skip/ignore this tag. It is possible? I heard that wildcards can help with this, but my attempts are unseccessful. Or maybe some manipulation with variables.
