The tool works as follows:

Step 1: In the uploaded Document it searches for headings equal to:

* `6\tVNFD TOSCA model`
* `7\tNSD TOSCA model`
* `8\tPNFD TOSCA model`,
* `9\tCommon Definitions`,

Step 2: For each of the section after the heading (and until the next heading is found), the tool searches for tables with the following properties:

* It contains only one cell (i.e. one row and one column) and
* the content matches the regular expression `^tosca\.[a-zA-Z\.:0-9\s]*$`, i.e. the text starts with `tosca.` and contains letters, numbers, `:` or white space.

Step 3: The four sets of generated definitions are written to files named:

* `generated_etsi_nfv_sol001_vnfd_types.yaml`
* `generated_etsi_nfv_sol001_nsd_types.yaml`
* `generated_etsi_nfv_sol001_pnfd_types.yaml`
* `generated_etsi_nfv_sol001_common_types.yaml`

Step 4: The files are archived in a zip file named `tosca_defs.zip` which is served as a response.
