將KML轉換爲GeoJson

我遇到了很多問題，因此我再次尋求幫助。將KML轉換爲GeoJson

我有這個巨大的文件http://d.pr/n/m3q6包含所有DMA對尼爾森我需要用PHP做某種方式通過每個解析，並從數據和座標，但他們以這種格式輸出

有一個工具，它可以（標準）KML轉換爲GeoJSON的（見下面的鏈接）。儘管如此，它是用nodejs編寫的。

有沒有人能夠使這項工作？我的數據是在一個JavaScript變量，我只是不能找出正確的格式的電話。我在'http：// mapbox.github.io/togeojson /'看到了這個例子，其中'out.value = JSON.stringify（toGeoJSON [format.value]（（new DOMParser（））。parseFromString（input .value，'text/xml'）），null，4）;'但它沒有意義..我沒有得到的是'toGeoJSON =（function（）{... '電話 – zipzit
