Question

我正在使用Google Maps API在1.1中进行GeoCode查找，而我正在使用XPathNavigator对象进入砖墙。

我需要创建一个“子导航器”，以便我们可以对节点执行全局xpath搜索（例如// adr：PostalCodeNumber），因为xml架构会根据返回的Address的准确性而更改。

以下是一个示例回复：

    <kml xmlns="http://earth.google.com/kml/2.0"><Response>
     <name>2601 S. McKenzie Street </name>
      <Status>
       <code>200</code>
       <request>geocode</request>
      </Status>
      <Placemark id="p1">
       <address>2601 S McKenzie St, Foley, AL 36535, USA</address>
       <AddressDetails Accuracy="8" xmlns="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0"><Country><CountryNameCode>US</CountryNameCode><CountryName>USA</CountryName><AdministrativeArea><AdministrativeAreaName>AL</AdministrativeAreaName><Locality><LocalityName>Foley</LocalityName><Thoroughfare><ThoroughfareName>2601 S McKenzie St</ThoroughfareName></Thoroughfare><PostalCode><PostalCodeNumber>36535</PostalCodeNumber></PostalCode></Locality></AdministrativeArea></Country></AddressDetails>

我有这个2.0代码块，我正在尝试为OuterXml属性找到1.1等价物：

private XPathNavigator CreateSubNavigator(XPathNavigator nav)
    {
        using (StringReader reader = new StringReader(nav.OuterXml))
        {
            XPathDocument doc = new XPathDocument(reader);
            return doc.CreateNavigator();
        }
    }

我发现了这篇博客文章，但是到SerializableXPathNavigator源的链接已经死了。 =（

请原谅我的无聊，但我如何使用自己的OuterXml方法编写自己的SerializableXPathNavigator类？

非常感谢你的帮助。
