我对Go来说还比较陌生,但是正在努力完成一项基本任务。我正在使用“ encoding / xml”包解析GPX文件,并具有以下示例xml数据;<gpx creator="StravaGPX" version="1.1" xmlns="http://www.topografix.com/GPX/1/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd http://www.garmin.com/xmlschemas/GpxExtensions/v3 http://www.garmin.com/xmlschemas/GpxExtensionsv3.xsd http://www.garmin.com/xmlschemas/TrackPointExtension/v1 http://www.garmin.com/xmlschemas/TrackPointExtensionv1.xsd http://www.garmin.com/xmlschemas/GpxExtensions/v3 http://www.garmin.com/xmlschemas/GpxExtensionsv3.xsd http://www.garmin.com/xmlschemas/TrackPointExtension/v1 http://www.garmin.com/xmlschemas/TrackPointExtensionv1.xsd" xmlns:gpxtpx="http://www.garmin.com/xmlschemas/TrackPointExtension/v1" xmlns:gpxx="http://www.garmin.com/xmlschemas/GpxExtensions/v3"> <metadata> <time>2013-02-16T10:11:25Z</time> </metadata> <trk> <name>Demo Data</name> <trkseg> <trkpt lat="51.6395658" lon="-3.3623858"> <ele>111.6</ele> <time>2013-02-16T10:11:25Z</time> <extensions> <gpxtpx:TrackPointExtension> <gpxtpx:atemp>8</gpxtpx:atemp> <gpxtpx:hr>136</gpxtpx:hr> <gpxtpx:cad>0</gpxtpx:cad> </gpxtpx:TrackPointExtension> </extensions> </trkpt>到目前为止,我能够获得以下几种类型的最基本的信息:type Gpx struct { Creator string `xml:"creator,attr"` Time string `xml:"metadata>time"` Title string `xml:"trk>name"` TrackPoints []TrackPoint `xml:"trk>trkseg>trkpt"`}type TrackPoint struct { Lat float64 `xml:"lat,attr"` Lon float64 `xml:"lon,attr"` Elevation float32 `xml:"ele"` Time string `xml:"time"` Temperature int `xml:"extensions>gpxtpx>atemp"`}我无法解析的地方是TrackPoint.Temperature。我无法正确匹配扩展下的命名空间节点的标记。关于我要去哪儿有什么建议吗?
