Automatic resubmission with unique ID incrementation

Good day everybody,

All I do in Soap UI opensource is manually submit requests to API endpoint. Then maually update the body of the call and submit again. I'd like to start changing that.

Lets assume I have an API call of following body:

<appId>001</appId>
<date>25 Nov 2019</date>
<text>hello forums</text>

submitted to API endpoint:

https://apiendpoint.com/hello

I'd like to ask if it's possible, and maybe if there's a tutorial, to achieve the following:

1. I want above XML body to be submitted to above endpoint 100 times, one after another.

2. I want API response to be written to a log file, along with the body of the call that produced it.

3. For each new submission of above call I want:

<appId>001</appId>

to be automatically incremented by +1.

I'll appreciate any advice,

thanks.
