Download XML File Here

So far i have tried Below Code but unable to complete. :(

$xml = New-Object XML
$XML.Load("D:\PSScript\BookStore.xml")
$xml.bookstore.Users.user |
Where-Object { ($_.Name -eq 'Richard')} |
Select-Object -Property Option

**Note : I want to use a condition here for example i want to change 1 Tag text value only for specific user, In short i want to modify text based on user id, Like where name = Richard change its <Option Name="Activate">1</Option> to <Option Name="Activate">0</Option> **

Answer 1

Your main problem is you need to treat option elements as arrays. I copied your xml snippet to a file called test.xml and this code works (I'll explain how I parsed through your xml file at each step to show where Option is displaying as an array):

[xml] $info = Get-Content test.xml #Shorthand for New-Object..Load
#This command isn't necessary but is helpful when looking for an attribute
$info | Format-List *

#From above command saw that $info.User is the base document element
$info.User
#showed Attribute in Option
$info.User.Option
#displayed an array element with Attribute as the 5 (6th cause you start at 0) index
$info.User.Option[5]
#displayed Name and #text attributes with #text = 1
$info.User.Option[5].'#text' = "0"
#updated #text attribute to 0

From this you should be able to modify your script to work with the full xml file.

As your still having problems, a better solution would be to adjust your xml so you can access each user as a full object rather then parsing through attributes:

     <User>
         <name>Richard</name>
         <pass>b56e0b4ea4962283bee762525c2d490f</pass>
         <containers>MasterVal</containers>
         <maxLimit>2</maxLimit>
         <minLimit>0</minLimit>
         <userLimit>0</userLimit>
         <activate>1</activate>
         <feedback></feedback>
         <forceSsl>2</forceSsl>
         <FileAllowed>
             <Disallowed />
             <Allowed />
         </FileAllowed>
         <Authorizations />
         <SpeedLimits DlType="0" DlLimit="10" ServerDlLimitBypass="2" UlType="0"
     UlLimit="10" ServerUlLimitBypass="2">
             <Download />
             <Upload />
         </SpeedLimits>
     </User>

Then you can access each user as $info.User.Richard and change each activate tags using $info.User.Richard.activate = 0 . If you cannot do this you'll need to use foreach:

[xml] $info = Get-Content test.xml
foreach ($i in $info.BookStore.Users.User) {
    if ($i.Name -eq "Richard") {
        foreach ($e in $i.Option) {
            if ($e.Name -eq "Activate") {
                $e.'#text' = "0"
            }
        }
    }
}

Then just write the xml back to the file. Note: Look at the use of select and select-xml if you want to simplify this later
