Delete all the elements of an array.
Copy
<xsql-script name='array_clear_test1'>
<body>
<array name='cities'>
<string>Barcelona</string>
<string>Paris</string>
<string>Roma</string>
</array>
<array.clear name='cities' />
<println><cities /></println>

The content of the structure is deleted with this function, erasing all the elements which compose the array. Another way to empty the variable ‘cities’, would be: <array.clear ><cities/></array.clear>
