配置单元到XML-视图中的xpath不起作用

我有一些XML要放在一个配置单元表中

<Locations>
<Location elevation="4.0" id="3062" latitude="57.819" longitude="-3.966" name="Tain Range"    region="he" unitaryAuthArea="Highland"/>
</Locations>

然后将其映射到视图

CREATE VIEW xpath_view(location_name)  
AS SELECT  
xpath_string(locationxml, 'Locations/Location/@name')
FROM xpath_table;  

---

我的xpath不工作。有人能指出我做错了什么吗？干杯

尝试“//Locations/Location/@name”不起作用。我尝试从xpath\u视图中选择*；它不会返回任何东西

CREATE VIEW xpath_view(location_name)  
AS SELECT  
xpath_string(locationxml, 'Locations/Location/@name')
FROM xpath_table;
