Hi,
I would like to print a comment containing only a dash (i.e., <!-----
) , but this is not allowed.
This is not permitted in XML; it's a syntax error. A - in a comment must be followed by a character that is not a hyphen. You can do, <!--- --> or <!-- - --> but not <!----->
There are no tricks or workarounds, it's illegal.
