Parse the XML files via `xmlschema` and the XSD definitions #5

Closed alexamici closed 3 years ago

alexamici commented 3 years ago

Most metadata are distributed in XML files (e.g. manifest.safe, product/swath and calibration files) and the product zip file contains part of the XSD definition to use.

As the XSD schemas are required when using xmlschema we need a way to always have a set of files. Strategy is:

  1. allow the user to specify a set of XSD files as a mapping from namespace to path to the schema file
  2. look for the distributed schema files based on a predefined product folder structure e.g. top_dir/support/s1-level-1-product.xsd
  3. use a mapping from namespace to shipped schema file

I think #11 is the last small step for closing this issue.
