How do i find the xpath of an XmlNode in c#?

I came across this problem today where I was trying to find the xpath of the current node, so i could access the parent and remove that node from the collection. I knocked together some useful code to remove this. It basically works out the position of that node in the document and then which child it is on the child node.

/// <summary>
        /// Gets an xpath to a node 
        /// </summary>
        /// <param name="node">Node to get xpath for</param>
        /// <returns>Xpath for node</returns>
        private static string GetXPathToNode(XmlNode node)
        {
            if (node.NodeType == XmlNodeType.Attribute)
            {
                // attributes have an OwnerElement, not a ParentNode; also they have
                // to be matched by name, not found by position
                return String.Format(
                    "{0}/@{1}",
                    GetXPathToNode(((XmlAttribute)node).OwnerElement),
                    node.Name
                    );
            }
            if (node.ParentNode == null)
            {
                //Have root node - so return empty path
                return "";
            }

            // the path to a node is the path to its parent, plus "/node()[n]", where 
            // n is its position among its siblings.
            return String.Format(
                "{0}/node()[{1}]",
                GetXPathToNode(node.ParentNode),
                GetNodePosition(node)
                );
        }

        /// <summary>
        /// Gets node position in relation to the child
        /// </summary>
        /// <param name="child">Child</param>
        /// <returns>Position on parent</returns>
        private static int GetNodePosition(XmlNode childNode)
        {
            for (int position = 0; position < childNode.ParentNode.ChildNodes.Count; position++)
            {
                if (childNode.ParentNode.ChildNodes[position] == childNode)
                {
                    // need to add one as xpath index starts not at zero
                    return position + 1;
                }
            }
            throw new InvalidOperationException("Missing Child Node");
        }
