從 Office 自訂工具自訂檔案檢視 XML 內容

Windows Script Host 概觀

若要執行指令碼，請使用 Windows Script Host (WSH)，這是和語言無關而與 Windows 指令碼引擎相關之 Scripting Host。

若要從 Windows 執行指令碼，會從 WScript.exe 提供 Windows 的對話方塊以設定指令碼屬性；若要從命令提示字元執行指令碼，會從 CScript.exe 提供命令列參數以設定指令碼屬性。

WSH 提供指令碼的拖曳支援。這表示您可以將檔案拖到 WSH 指令碼上。檔案名稱會轉換成命令列上的引數。

如需 WSH 的相關資訊，請參閱 MSDN 網站上的下列資源：

• Windows Script Host 基本概要 (可能為英文網頁) (https://go.microsoft.com/fwlink/?linkid=100317\&clcid=0x404) (可能為英文網頁)

• 執行指令碼 (可能為英文網頁) (https://go.microsoft.com/fwlink/?linkid=100319\&clcid=0x404) (可能為英文網頁)

ExtractOctXml.vbs 指令碼範例

下列各節提供 Visual Basic 指令碼 ExtractOctXml.vbs 範例，以及使用指令碼從 OCT .msp 自訂檔擷取 XML 中繼資料的說明。

若要儲存指令碼範例，請開啟文字編輯器 (例如記事本)，然後將本節中的指令碼程式碼複製並貼到檔案中。請將指令碼檔案儲存成 ExtractOctXml.vbs。
