Metadata Editor is not writing ENVI-style lists correctly

[Andreas Janz]

In the ENVI domain, lists are wrapped by {} brackets, e.g.:

<MDI key="wavelength">{0.46, 0.465, 0.47, ... }

After changing such lists in the Metadata Editor and save, the brackets are gone. This introduces problems in following algorithms!

<MDI key="wavelength">123.456, 0.465, 0.47, ...

Which algorithms are affected?

[Benjamin Jakimow]

This regex allows for relaxed parsing of ENVI list values, no matter they start or end with braces. List values could even include braces (nam{me), though I think this is not ENVI style any more

import re
text2parse= '{    42.23  ,  na{me   }'
re.split('\s*,\s*', re.sub('(^\s*{\s*|\s*}\s*$)', '', text2parse))
['42.23', 'na{me']

))

[Andreas Janz]

Thanks for the workaround, but you really should write the new list in the original format. Its not good to switch formats in between.

resolves #622 : wraps list values into braces in case they are written to the GDAL domain "ENVI" (vulnerable algorithms might expect brace wrapping like in none-XML ENVI header files: https://www.l3harrisgeospatial.com/docs/enviheaderfiles.html)
