動機

您需要執行一個外部程序，例如 shell 命令。

執行程序命令

  process:execute($command as xs:string, $options as node()) as item()*

選項示例

目前僅記錄了兩個選項。工作目錄和標準輸入的值

<options>
    <workingDir>PATH TO LOCAL FILE SYSTEM</workingDir>
    <stdin><line>INPUT STRING</line></stdin>
</options>

示例程式

XQuery 檔案

import module namespace process="http://exist-db.org/xquery/process" at "java:org.exist.xquery.modules.process.ProcessModule";

let $cmd := 'D:\Apps\git\bin\ls.exe'
return
<results>
{process:execute($cmd, <options/>)}
</results>

示例輸出

以下是一個執行 git "ls" 命令的示例，該命令沒有任何選項。請注意，預設值為 EXIST_HOME 目錄。
