Hi Robert,

I really like to use the typeswitch statement for things like this:

declare function t:replace($node as node()) as node() {
    typeswitch ($node)
        case $elem as element(services) return
                <service value="false">1</service>
                <service value="true">2</service>
                <service value="false">3</service>
        case $elem as element() return
           element { node-name($elem) } {
                $elem/@*, for $child in $elem/node() return t:replace($child)
        default return $node
