xml_get_current_column_number — Get current column number for an XML parser
Gets the current column number of the given XML parser.
A reference to the XML parser to get column number from.
This function returns FALSE if parser does not refer to a valid parser, or else it returns which column on the current line (as given by xml_get_current_line_number()) the parser is currently at.
Column numbers apparently start at 0. So you may want to add 1.
"Column number" refers to the current character position within the current line of the XML document.
