```go
package main

import (
	"fmt"
	"libvirt.org/go/libvirtxml"
)

func main() {
	// Parse a PCI device XML (typically obtained from libvirt)
	deviceXML := `<device>
  <name>pci_0000_03_00_0</name>
  <path>/sys/devices/pci0000:00/0000:00:01.0/0000:03:00.0</path>
  <parent>pci_0000_00_01_0</parent>
  <driver>
    <name>nvidia</name>
  </driver>
  <capability type="pci">
    <class>0x030000</class>
    <domain>0</domain>
    <bus>3</bus>
    <slot>0</slot>

      <address domain="0x0000" bus="0x03" slot="0x00" function="0x1"/>
    </iommuGroup>
  </capability>
</device>`

	var device libvirtxml.NodeDevice
	err := device.Unmarshal(deviceXML)
	if err != nil {
		panic(err)
	}

	fmt.Printf("Device: %s\n", device.Name)
	fmt.Printf("Path: %s\n", device.Path)
	if device.Driver != nil {
		fmt.Printf("Driver: %s\n", device.Driver.Name)
	}
	if device.Capability.PCI != nil {
		pci := device.Capability.PCI
		fmt.Printf("PCI: %04x:%02x:%02x.%x\n", *pci.Domain, *pci.Bus, *pci.Slot, *pci.Function)
		fmt.Printf("Product: %s (%s)\n", pci.Product.Name, pci.Product.ID)
		fmt.Printf("Vendor: %s (%s)\n", pci.Vendor.Name, pci.Vendor.ID)
