Stepping through Child Table Rows

Since this wasn’t quite the most obvious, and I’ve noticed in two companies so far that “yer doin’ it wrong,” I thought I’d share the easiest and most readable method for stepping through child table rows in velocity, when you don’t want to create a separate template:

#foreach( $row in $sys.item.getNodes( '[i]child_table_name[/i]' ) )
$row.getProperty( 'rx:[i]field_name[/i]' ).String

To clarify, this method is intended for child tables with more than 1 column and where you want to display more than one of the columns at a time.

Is there a way to do this in an initslot? I seem to not be able to access the child table from an initslot.
