Currently, Flow can only read XML, but we should start looking into saving XML files as well.

There are two libraries that could help us achieve that:

• https://github.com/veewee/xml
• https://github.com/saloonphp/xml-wrangler (this one operate son top of veewee/xml)

Before actual coding, we should first look into converting Rows into XML, we will need to figure out how to determine what should be saved as a value and what should be saved as an attributes.
