我是 openlayers 的新手，正在尝试在我的浏览器中显示 gml 层，其中包含硬盘驱动器中的所有内容。我已经尝试了以下代码，但我一生都无法让它工作。xml 文件可以从以下网址下载：ftp: //webftp.vancouver.ca/opendata/xml/weekendplayfieldstatus.xml。它与我的 html 文件位于同一目录中。提前感谢您的帮助。

我相信您只是错过了将 GML 图层添加到地图的调用。

var layerGML = new OpenLayers.Layer.GML("GML", "weekendplayfieldstatus.xml");    
map.addLayer(layerGML);
