3%   K = XML_FINDSTR(TEXT,PATTERN) returns the starting indices of any
4%   occurrences of the string PATTERN in the string TEXT.
5%
6%   K = XML_FINDSTR(TEXT,PATTERN,INDICE) returns the starting indices
7%   equal or greater than INDICE of occurrences of the string PATTERN
8%   in the string TEXT. By default, INDICE equals to one.

11%   starting indices equal or greater than INDICE of occurrences of
12%   the string PATTERN in the string TEXT. By default, INDICE equals
13%   to one and NBOCCUR equals to Inf.
