Create a large file for a BulkProcess test in SoapUI Pro

Hello,

I would like to know how to do the following in SoapUI pro. I want to process a bulkorder that looks like this:

<XML>
 <request 1> 
  <field a></field a> 
  <field b></field a>
  <field c></field a>
 </request 1> 

 <request 2>
  <field a></field a>
  <field b></field a>
  <field c></field a>
 </request 2>

  <request 3>
  <field a></field a>
  <field b></field a>
  <field c></field a>
 </request 3>
</XML>

But not just 3 but several thousands so writing it is not an option.

So i made it data driven with an excel sheet with 1000 of records but i realised that is not what i want to achieve because it just processes the file 1 at a time with different data. Just doing 1 request at a time until EOF.

Also a load test is not what i need. Because the client will want to process one single large file. There not 1000 of users wanting to process these files at once.

So in short i just want to have one huge file with tons of records processed as 1 requests. Not tons of 1 request in sequence.

Can anyone give me some advice?

Many thanks
