[xml] Retrieve a nodes column number

[Daniel Nagy <danielnagy gmx de>]

Hi,

I have seen that it is possible to get the line number of a node by 
calling "xmlGetLineNo" [1] on the node.
The parser must have had the "xmlLineNumbersDefault" flag activated 
before parsing to get this to work.

Now I am wondering whether it is possible to retrieve the column number 
in which the node was during parsing.

I am working on an interactive xpath editor which should highlight 
nodes matched on a xpath query.
Without the column information I can only highlight the whole line in 
which the tag matched.

Thank you for your help.
Best
