QML XmlListModel和car2go xml解析

我无法解析qml xmllistmodel中的car2go响应。QML XmlListModel和car2go xml解析

<kml xmlns:ns3="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0" xmlns:ns2="http://www.w3.org/2005/Atom"

         <ExtendedData> 
           <Data name="fuel"> 
             <value>24</value> 
           </Data> 
           <Data name="interior"> 
             <value>EXCELLENT</value> 
           </Data> 
           <Data name="exterior"> 
             <value>EXCELLENT</value> 
           </Data> 
           <Data name="vin"> 
             <value>WME4513001K154655</value> 
           </Data> 
         </ExtendedData> 
         <Point> 
           <coordinates>10.029,48.4362,0</coordinates> 
         </Point> 
       </Placemark> 
     </Document> 
</kml>

和我的代码是

XmlListModel { 
    namespaceDeclarations: "declare namespace ns2='http://www.w3.org/2005/Atom';declare default element namespace 'http://www.opengis.net/kml/2.2'" 
    query: "/kml/Document/Placemark" 
    XmlRole { name: "plate_number"; query: "name/string()" } 
    XmlRole { name: "address"; query: "description/string()" } 
    XmlRole { name: "fuel"; query: "ExtendedData/Data[1]/string()" } 
    XmlRole { name: "interior"; query: "ExtendedData/Data[2]/string()" } 
    XmlRole { name: "exterior"; query: "ExtendedData/Data[3]/string()" } 
    XmlRole { name: "vin"; query: "ExtendedData/Data[4]/string()" } 
    XmlRole { name: "coordinates"; query: "coordinates/string()" } 
}

但我得到

错误XPST0003文件...语法错误，意想不到的NCName，期待; QML XmlRole：无效的问题：“名/串（）”等

在此先感谢

第二个命名空间声明缺少终止的分号。

更换

namespaceDeclarations: "declare namespace ns2='http://www.w3.org/2005/Atom';declare default element namespace 'http://www.opengis.net/kml/2.2'"

与

namespaceDeclarations: "declare namespace ns2='http://www.w3.org/2005/Atom';declare default element namespace 'http://www.opengis.net/kml/2.2';"

应该修复它。

解析数据的排序如何？我想计算每个car2go到坐标X，Y的距离并将其显示为递增。 – Temirlan 2011-04-02 06:14:39
