Magento – Magento2 Delta Migration Issue

I have already migrated from Magento1 but after completed migration, I've added some more products on Magento1 site & also some customers have been added.

So I want to include those products,categories,customers,orders etc.

For that I'm using "Delta migration" command :-

php bin/magento migrate:delta  vendor/magento/data-migration-tool/etc/opensource-to-opensource/1.9.3.8/config.xml

But getting below error:-

  [Migration\Exception]
  XML file is invalid.

migrate:delta [-r|--reset] [-a|--auto] [--] <config>

Why I'm getting this ?please help me to resolve this issue.

Note:-

1. I'm using Magento2.2.5 & Magento1.9.3.8 version

2. As per my R&D, by using delta migration we can't migrate products,categories again.is this correct or not ?

Here is config.xml file code:-
