XSLT沒有選擇某一組節點（只有第一個兄弟？）

Question

我知道標題可能很難理解。我將列出XML和XSLT，希望它會更清晰。

請看看照片。您將看到平臺永遠不會添加到Adobe Photoshop的操作系統單元中。恰巧，Adobe Photoshop位於software_inventory節點下的列表頂部。我不知道這是否是原因。我嘗試了一下代碼，它從來沒有選擇Adobe Photoshop的平臺。有沒有人知道爲什麼會發生這種情況？我能做些什麼來解決它？

謝謝， 大衛

Answer 1

這是因爲Adobe公司的Photoshop元素是

<Platform></Platform> 

後，檢查platform。這是區分大小寫的，請使用

<platform>Windows 7</platform> 

改爲。
