虽然root div的所有子节点都没有前缀，但它们位于命名空间中，该命名空间指定了它的属性。因此，您无法以通常的方式引用它们

使用DomDocument代码可能是：

$xml = simplexml_load_string($string);
$xml->registerXPathNamespace('o', "http://www.w3.org/1999/xhtml");
foreach($xml->xpath('//o:p/o:a') as $a) 
     echo $a . "\n";

或使用SimpleXML：

public class Joystick : MonoBehaviour, IPointerDownHandler, IPointerUpHandler, IDragHandler
{
    public enum AxisOption
    {
        // Options for which axes to use
        Both, // Use both
        OnlyHorizontal, // Only horizontal
        OnlyVertical // Only vertical
    }

    public int MovementRange = 100;
    public AxisOption axesToUse = AxisOption.Both; // The options for the axes that the still will use
    public string horizontalAxisName = "Horizontal"; // The name given to the horizontal axis for the cross platform input
    public string verticalAxisName = "Vertical"; // The name given to the vertical axis for the cross platform input

    Vector3 m_StartPos;
    bool m_UseX; // Toggle for using the x axis
    bool m_UseY; // Toggle for using the Y axis
    CrossPlatformInputManager.VirtualAxis m_HorizontalVirtualAxis; // Reference to the joystick in the cross platform input
    CrossPlatformInputManager.VirtualAxis m_VerticalVirtualAxis; // Reference to the joystick in the cross platform input

    void OnEnable()
    {
        CreateVirtualAxes();
    }

    void Start()
    {
        m_StartPos = transform.position;
    }

    void UpdateVirtualAxes(Vector3 value)
    {
        var delta = m_StartPos - value;
        delta.y = -delta.y;
        delta /= MovementRange;
        if (m_UseX)
        {
            m_HorizontalVirtualAxis.Update(-delta.x);
        }

        if (m_UseY)
        {
            m_VerticalVirtualAxis.Update(delta.y);
        }
    }

    void CreateVirtualAxes()
    {
        // set axes to use
        m_UseX = (axesToUse == AxisOption.Both || axesToUse == AxisOption.OnlyHorizontal);
        m_UseY = (axesToUse == AxisOption.Both || axesToUse == AxisOption.OnlyVertical);

        // create new axes based on axes to use
        if (m_UseX)
        {
            m_HorizontalVirtualAxis = new CrossPlatformInputManager.VirtualAxis(horizontalAxisName);
            CrossPlatformInputManager.RegisterVirtualAxis(m_HorizontalVirtualAxis);
        }
        if (m_UseY)
        {
            m_VerticalVirtualAxis = new CrossPlatformInputManager.VirtualAxis(verticalAxisName);
            CrossPlatformInputManager.RegisterVirtualAxis(m_VerticalVirtualAxis);
        }
    }

    public void OnDrag(PointerEventData data)
    {
        Vector3 newPos = Vector3.zero;

        if (m_UseX)
        {
            int delta = (int)(data.position.x - m_StartPos.x);
            newPos.x = delta;
        }

        if (m_UseY)
        {
            int delta = (int)(data.position.y - m_StartPos.y);
            newPos.y = delta;
        }

        var newPosition = new Vector3(newPos.x, newPos.y, newPos.z);

        transform.position = Vector3.ClampMagnitude(newPosition, MovementRange) + m_StartPos;

        UpdateVirtualAxes(transform.position);
    }

    public void OnPointerUp(PointerEventData data)
    {
        transform.position = m_StartPos;
        UpdateVirtualAxes(m_StartPos);
    }

    public void OnPointerDown(PointerEventData data) { }
}
