Number of the elements of an array.
Copy
<xsql-script name='array_size_test1'>
<body>
<array name='cities'>
<string>Barcelona</string>
<string>Paris</string>
<string>Rome</string>
</array>
<println><array.size name='cities' /></println>
</body>
</xsql-script>
An alternative to obtain the number of cities which contains the variable, less elegant but equally valid, would be:
Copy
<array.size><cities/></array.size>
The result is:
Copy
