Question

我无法在qml xmllistmodel中解析car2go响应。

                                </Data>
                                <Data name="exterior">
                                        <value>EXCELLENT</value>

                                <Data name="vin">
                                        <value>WME4513001K154655</value>
                                </Data>
                        </ExtendedData>

                        </Point>
                </Placemark>
        </Document>
 </kml>

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()" }
}

但我确实得到了

文件中的错误XPST0003 ...语法错误，意外的NCName，期待; QML XmlRole：无效查询：“name / string（）”等。

提前致谢

Answer 1

第二个名称空间声明缺少终止分号。

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。
