Образец кода: благодаря Vonpryz он предоставил измененный способ извлечения данных, но теперь я все еще пытаюсь понять, как бороться сCSV избранных номеров жизни. Есть ли способ заставить вызов @lifenumber идти против группы чисел в CSV?

[xml]$p = get-content C:\Scripts\source\Hospitalone_XML.xml
# Search by lifenumber
$nl = $p.SelectNodes('/People/Person[@lifenumber="27091"]')
# Check the email
$nl.email
$nl.lname
$nl.fname
# How many appointments?
$nl.appointment.count
# See the titles
$nl.appointment | % { $_.title }
$nl.appointment | % { $_.deptcode }

Answer 1

Предполагается, что у вас есть CSV-файл со столбцом lifenumber:

$CSV = Import-Csv numbers.csv
[xml]$p = Get-Content C:\Scripts\source\Hospitalone_XML.xml

foreach($row in $CSV){
    $people = $p.SelectNodes(('/People/Person[@lifenumber="{0}"]' -f $row.lifenumber))
    # work with $people here
}
