OpenCOLLADA need a little c++ help

[Richard Shaw]

OpenCOLLADA has been failing to build with gcc 13 due to[1]:

error: possibly dangling reference to a temporary
[-Werror=dangling-reference]
  315 |                 const auto & parents =
dae.root().selectNodes("//*[@sid]/..");

The code in question[2] is:
  // InstanceWithExtra and other <instance_*> with "url" attribute
const auto & instances = root().selectNodes(
xpath_all + Strings::instance_animation +
xpath_or_all + Strings::instance_camera +
xpath_or_all + Strings::instance_controller +
xpath_or_all + Strings::instance_effect +
xpath_or_all + Strings::instance_force_field +
xpath_or_all + Strings::instance_formula +
xpath_or_all + Strings::instance_geometry +
xpath_or_all + Strings::instance_image +
xpath_or_all + Strings::instance_joint +
xpath_or_all + Strings::instance_kinematics_model +
xpath_or_all + Strings::instance_kinematics_scene +
xpath_or_all + Strings::instance_light +
xpath_or_all + Strings::instance_node +
xpath_or_all + Strings::instance_physics_material +
xpath_or_all + Strings::instance_physics_model +
xpath_or_all + Strings::instance_physics_scene +
xpath_or_all + Strings::instance_visual_scene
);
for (auto instance : instances)
if (auto url = instance.attribute(Strings::url))
onAnyDAEURI(instance.line(), url.value());

There's a 2nd instance of the error but I think I can fix it once the path
forward on the first is addressed.

Thanks,
Richard
