Failed to parse internal XML file xl/comments95.xml

[GeoffRussell]

I've downloaded a bunch (649) of xlsx files from the UNFCCC ... National Greenhouse gas inventories. While XLSX parses most of them successfully, there are a few with the following error ...

ERROR: LoadError: XMLError: Document is empty from XML parser (code: 4, line: 1)

See attached file ...

I certainly don't need the "internal XML file", so some way of ignoring them would be enough of a workaround for
me.

Many thanks

Further to this issue ... I can't read 203 of the 649 files.

I'm slowly learning about these xlsx files ... from a position of total ignorance. It seems like the problems are due to some of these so-called comments files being empty. Why should an empty file be considered a showstopper?

[GeoffRussell]

If I put some properly formatted xml in the comments file, the problem vanishes. But there can be multiple empty comments file in each xlsx file and I can't work out a method of automating the patching process.
