所以我對XML和HTML相當陌生，並且一直在w3schools.com上查找指南。下面是與一個這樣的例子相關的兩個文件，它是關於解析代碼的。我想我對代碼的工作原理有所瞭解，並且在他們的在線「自己嘗試」的情況下，它會起作用。我的問題是，我下載文件後無法運行。也許我沒有設置好目錄，或者我完全錯過了一些東西。如何用HTML解析這個XML示例代碼？

如果我失去了一些東西，請告訴我，我一直在試圖研究它自己的天。
在控制檯中是否出現錯誤？你是從Web服務器提供文件，還是僅在文件夾中？ –
我只是把它們放在一個文件夾中。爲了測試它，我剛剛嘗試在IE中運行.html文件，但每次我只做一個空白的屏幕時就會打開。 – calebben3
嘗試在Chrome中運行它，按開發者控制檯（新的最好的朋友）的F12並查看它是否顯示安全異常。您無法使用JavaScript從文件系統加載文件，以防止網站只讀取您的數據，因此如果您需要這樣做，最簡單的方法就是在本地安裝Apache。 –
