      Description

      This is a similar problem to one that was earlier fixed in MySQL-5.0 under terms of:
      Bug#27586 Wrong autoinc value assigned by LOAD DATA in the NO_AUTO_VALUE_ON_ZERO mode

      Now for LOAD XML instead of LOAD DATA.

      I put a file MYSQL_HOME_DIR/test/t1.xml with this content:

      <list>
        <row a="1" b="bbb1"/>
        <row b="bbb2"/>
      </list>
      

      and run this script:

      SET @@SQL_MODE=NO_AUTO_VALUE_ON_ZERO;
      CREATE OR REPLACE TABLE t1(a INT AUTO_INCREMENT PRIMARY KEY, b TEXT);
      LOAD XML INFILE 't1.xml' INTO TABLE t1 ROWS IDENTIFIED BY '<row>';
      SELECT * FROM t1 ORDER BY b;
      

      It returns the following data:

      +---+------+
      | a | b    |
      +---+------+
      | 1 | bbb1 |
      | 0 | bbb2 |
      +---+------+
      

      The auto-increment value for the second record is wrong. It should be 2 rather than 0.
