如果您特别了解要查找的元素，则可以像这样简单地指定元素:

If you specifically know the elements that you are looking for then you can simply specify the element like so:

# Read the existing file
[xml]$xmlDoc = Get-Content $xmlFileName

# If it was one specific element you can just do like so:
$xmlDoc.config.button.command = "C:\Prog32\folder\test.jar"
# however this wont work since there are multiple elements

# Since there are multiple elements that need to be 
# changed use a foreach loop
foreach ($element in $xmlDoc.config.button)
{
    $element.command = "C:\Prog32\folder\test.jar"
}

# Then you can save that back to the xml file
$xmlDoc.Save("c:\savelocation.xml")
