Re: [xsl] Anyone have XSLT that generates XML showing a Windows folder s

Hi Roger,

There are too-many characters that are allowed in a directory-name that
will break the syntax for an XML element name:

seems like any character except:  (0 to 31)!codepoints-to-string(.),  \, /
, ?,:, *, ", <, >, |

So you can have commas, whitespace (consecutive spaces), %, ;, +, &, etc.
For reference see for example this:
https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file    ,

Therefore, a safer way to represent a directory structure would be to make
the file and directory names values, not names.

Even in this case, the & (ampersand) character must be watched for and
escaped properly.

Also, given an XML file in this format, that is believed to represent a
directory, may actually not represent a real windows filesystem directory,
as there are reserved names that have special meaning and are not allowed
to be used:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9,
LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these
names followed immediately by an extension; for example, NUL.txt

One more thing: you might have a problem if the length of a full
filepath exceeds 250.

HTH, :)

Cheers,
Dimitre
