I suggest a bit different approach which involves creating a new function. Just add a new parameter for the root element name, rename this function, and create a new one with the original name which would be a tiny wrapper around the renamed function passing "domain" as the root element name. This way you can keep existing code untouched and just call the new function when you need a different root element name. In other places we sometimes separate formatter for the internals from the code formatting the container element. But since we need to add attributes to the container element, such approach would be quite ugly in this case.

[libvirt] [PATCH v3 1/2] qemu: formatting XML from domain def choosing the root name
The function virDomainDefFormatInternal() has the predefined root name "domain" to format the XML. But to save both active and inactive domain in the snapshot XML, the new root name "inactiveDomain" was created. So, this function was modified to be driven by the new flag VIR_DOMAIN_DEF_FORMAT_INACTIVE_NODE to choose the correct root name. Signed-off-by: Maxiwell S.
