What does this mean exactly? How does one “suppressing the column” in an XML?
Note that the column that it shown you is just a position at which the reader was at the time of the error; the actual position is most likely earlier.
The problem should be identified in an XML editor, e.g. using such an editor’s validation function, which can show you the same position(s) in the file that would break in LibreOffice.
There is an XML plugin for Notepad++; but it is really poor - because it doesn’t represent you the XML in a readable form, unless you do an editing operation (“pretty print”); and that editing function breaks many things in XML, e.g. places where XML requires taking spaces into account (xml:space="preserve"). And it doesn’t show you the error location properly with overlong lines.
So e.g. my procedure is like that: use Notepad++'s XML plugin’s “pretty print”; use its “check XML syntax”; find the problem; notice some unique identifier nearby; undo the pretty-printing; find the same place using the identifier; do the changes to correct improper XML structure; repeat (usually, there would be more than one similar error).
Or you could attach the problematic file here, taking into account that it would be publicly accessible.
