The IpAddr field of the AggInfoXml struct is a slice.
Slices have no fields; but they have elements which should be accessed
through the indexing operation, like in aggInfoXml[0] for instance.
Hence "aggInfoXml.IpAddr.Hports" has no sense at all.
You might want to use
for _, addr := range range aggInfoXml.IpAddr {
for _, port := range addr.Hports {
}
}
or something like this -- that is, Hports is only defined on instances
of type Addr, not on slices of this type.
