Example

Remove the first element of an array.

Copy

<xsql-script name='array_removeFirst_test1'>
    <body>
        <array name='cities'>
            <string>Barcelona</string>
            <string>Paris</string>
            <string>Roma</string>
        </array>

        <array.removeFirst name='cities' />

        <println><cities/></println>
    </body>
</xsql-script>

†he first element from the collection of cities, which is 'Barcelona', is removed. An alternative to erase the first string, less elegant but equally valid, would be:

Copy

<array.removeFirst/><cities/></array.removeFirst>

The result is:

Copy

Paris
Roma
