Sql server 从SSIS xml文件提取信息？

我正在尝试从平面文件源连接获取字段列表。我尝试了以下powershell命令

[xml]$p = cat .\package.dtsx
$p.Executable.ConnectionManager

它回来了

Property ObjectData -------- ---------- {DelayValidation, ObjectName, DTSID, Description...} ObjectData {DelayValidation, ObjectName, DTSID, Description...} ObjectData {DelayValidation, ObjectName, DTSID, Description...} ObjectData {DelayValidation, ObjectName, DTSID, Description...} ObjectData {DelayValidation, ObjectName, DTSID, Description...} ObjectData {DelayValidation, ObjectName, DTSID, Description...} ObjectData {DelayValidation, ObjectName, DTSID, Description...} ObjectData ......

---

通过玩游戏，我找到了找到特定联系的方法

$c = $p.Executable.ConnectionManager | ? { $_.Property[1]."#text" -eq "XXX" }

现在需要获取所有列。下面的语句获取xml

$c.ObjectData.ConnectionManager.OuterXml

但是，数据类型是整数

$c.ObjectData.ConnectionManager.OuterXml
