配合单例类一起使用，可以获取Xml表中存储的模型的具体位置，转换成可以直接使用的Vector3和Vector4类型的变量。

using UnityEngine;
using System.Collections;

public class StringCommon : Singleton<StringCommon>
{
    //去除字符串中的逗号
    public string[] SplitStringWithComma(string str)
    {
        string[] temp = str.Split(',');
        return temp;
    }

    //获取Vector3类型的变量
    public Vector3 GetVector3Value(string value)
    {
        string newPos = value.Replace("(", "");
        string lastPos = newPos.Replace(")", "");
        Vector3 vector3Value = new Vector3(
            float.Parse(SplitStringWithComma(lastPos)[0]),
            float.Parse(SplitStringWithComma(lastPos)[1]),
            float.Parse(SplitStringWithComma(lastPos)[2])
            );
        return vector3Value;
    }

    //获取Vector4类型的变量
    public Vector4 GetVector4Value(string value)
    {
        string newPos = value.Replace("(", "");
        string lastPos = newPos.Replace(")", "");
        Vector4 vector4Value = new Vector4(
            float.Parse(SplitStringWithComma(lastPos)[0]),
            float.Parse(SplitStringWithComma(lastPos)[1]),
            float.Parse(SplitStringWithComma(lastPos)[2]),
            float.Parse(SplitStringWithComma(lastPos)[3])
            );
        return vector4Value;
    }    
}

因为xml表中的内容都是直接代码生成的类似这样：Position=”(6.29, -23.83, -11.58)”
所以想使用可以通过上面的脚本来转换一下成为new Vector3(6.29, -23.83, -11.58);
如果有更好的方法，希望能一起探讨，xml表是通过CreateSceneElements脚本实现，内容如下：

using UnityEngine;
using UnityEditor;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Xml;

public class CreateSenceElements : EditorWindow
{
    [MenuItem("Sence/"+"生成场景元素XML表")]
    static void SenceElements()
    {
        GameObject obj_Father = Selection.activeGameObject;
        string filepath = Application.dataPath + "/StreamingAssets" + @"/" + obj_Father.name + ".xml";
        //创建XML文档实例
        XmlDocument xmlDoc = new XmlDocument();
        //创建root节点，也就是最上一层节点
        XmlElement root=null;
        XmlElement rootSence = null;
        XmlElement rootPrefab = null;
        if (!File.Exists(filepath))
        {
            //创建root节点，也就是最上一层节点
            root = xmlDoc.CreateElement(obj_Father.name);
            rootSence = xmlDoc.CreateElement("SenceElement");
            rootPrefab = xmlDoc.CreateElement("SencePrefab");
            root.SetAttribute("ID", "ID001");
            Debug.Log("createXml OK!");
        }
        else
        {
            xmlDoc.Load(filepath);
            root = xmlDoc.SelectSingleNode(obj_Father.name) as XmlElement;
            rootSence = xmlDoc.SelectSingleNode("SenceElement") as XmlElement;
            rootPrefab = xmlDoc.SelectSingleNode("SencePrefab") as XmlElement;
            root.RemoveAll();
        }
        //保存场景中元素的名称
        Dictionary<string, int> dicPrefabs = new Dictionary<string, int>();

        FindChild(ref xmlDoc, ref rootSence, dicPrefabs, obj_Father.transform, 0);

        foreach (string key in dicPrefabs.Keys)
        {
            XmlElement _ele = xmlDoc.CreateElement("PrefabNode");
            _ele.SetAttribute("name", key);
            _ele.SetAttribute("num", dicPrefabs[key].ToString());
            rootPrefab.AppendChild(_ele);
        }
        root.AppendChild(rootPrefab);
        root.AppendChild(rootSence);
        xmlDoc.AppendChild(root);
        //把XML文件保存至本地 
        xmlDoc.Save(filepath);
        AssetDatabase.Refresh();
    }
    static void FindChild(ref XmlDocument doc, ref XmlElement node,Dictionary<string,int> dic, Transform tran ,int level)
    {
        ++level;
       foreach (Transform child in tran)
       {           
           XmlElement _ele = doc.CreateElement("SenceNode" + level.ToString());
           _ele.SetAttribute("name", child.name);
           _ele.SetAttribute("Position", child.localPosition.ToString("0.00"));
           _ele.SetAttribute("EulerAngles", child.localEulerAngles.ToString("0.00"));
           _ele.SetAttribute("Scale", child.localScale.ToString("0.00"));
           MeshFilter _mesh = child.GetComponent<MeshFilter>();
           if (_mesh!=null)
           {
               string _str = _mesh.sharedMesh.name;
               _ele.SetAttribute("Prefab", _str);
                MeshRenderer _render = child.gameObject.GetComponent<MeshRenderer>();
                _ele.SetAttribute("LightMapScale", _render.lightmapScaleOffset.ToString("0.000000"));
                _ele.SetAttribute("LightMapIndex", _render.lightmapIndex.ToString());
                if (dic.ContainsKey(_str))
               {
                   dic[_str] = dic[_str] + 1;
               }
               else dic.Add(_str, 1);             
           }
           if (child.childCount >= 1)
           {
               FindChild(ref doc, ref _ele,dic, child, level);
           }
           node.AppendChild(_ele);
       }
    }
