我需要填充如下

我能够提取工作表名称，但无法继续（Powershell 新手）

样本XML：

不确定这是否正是您所需要的，但它可能会提示您如何使用逻辑来解析您的 XML。

$result = foreach($file in Get-ChildItem *.xml) {
    [xml]$xml = Get-Content $file
    foreach($ws in $xml.workbook.worksheets.worksheet) {
        $wsname = $ws.name
        foreach($tb in $ws.table) {
            $tbname = $tb.view.datasources.datasource.caption
            foreach($col in $tb.view.'datasource-dependencies'.'column-instance'.column) {
                [pscustomobject]@{
                    FileName                 = $file.Name
                    'DATASOURCE_CAPTION'     = $tbname
                    'WORKSHEET NAME'         = $wsname
                    'COLUMN-INSTANCE_COLUMN' = $col
                }
            }
        }
    }
}

$result | Format-Table

我将你的 XML 存储为 example.xml (FileName 属性)，结果如下：

FileName    DATASOURCE_CAPTION WORKSHEET NAME        COLUMN-INSTANCE_COLUMN
--------    ------------------ --------------        ----------------------
example.xml App Info           App Info              [App_Info_Grp]
example.xml App Info           App Info              [Primary_ID]
example.xml App Info           App Info by PrimaryID [App_Info_Type]
example.xml App Info           App Info by PrimaryID [EIN]
