Producing XML Output

1.25.1 Problem

You'd like to turn a query result into XML.

1.25.2 Solution

mysql can do that for you.

1.25.3 Discussion

mysql creates an XML document from the result of a query if you use the -X (or --xml) option. Here's an example that shows the difference between tabular format and the XML created from the same query:

% mysql -e "SELECT * FROM limbs WHERE legs=0" cookbook
+------------+------+------+
| thing | legs | arms |
+------------+------+------+
| squid | 0 | 10 |
| octopus | 0 | 8 |
| fish | 0 | 0 |
| phonograph | 0 | 1 |
+------------+------+------+
% mysql -X -e "SELECT * FROM limbs WHERE legs=0" cookbook



 
 squid
 0
 10
 

 
 octopus
 0
 8
 

 
 fish
 0
 0
 

 
 phonograph
 0
 1
 

-X and --xml may be used as of MySQL 4.0. If your version of MySQL is older than that, you can write your own XML generator. See Recipe 10.42.
