Import multiple xml via Web from cloud based software

Hi PowerBI Community,

I am loading data from my cloud-based invoice software (https://invoiceocean.com/). I use Web as the data source and paste XML url with token provided by software. Unfortunately, the software has limitation. It allows fetching max up to 100 rows at once in one link (max_rows =100)

My solution is as follows: 

Every time when I reach next hundred rows I need to make copy of table, change xml string and append the final table.

Additionally, I am not able to create the table when at least one document is not created. I.e. I created table 601 -700. Total rows in software is 550, so I receive the error message: 

Questions: 

1. Is there any solution  (maybe advanced editor) to combine multiple XML links into one table without creating Data Warehouse or other additional storage?

2.  Is it possible to use the condition which checks if XML link is empty? If yes it stops, else it loads data?

Thanks,

Radek
