Modify XML file

Is there a way to modify an XML file using powershell? I poked around
in the help and on google, but didn't find anything.

I try to replace the contents of a single tag. The tag is unique and
formatting is consistent so I could also use a simple text
search-and-replace.

Thanks!

you do SOMETHING like this (just out of my head so sorry if there are
mistakes)

$a = [xml]get-content myfile.xml
$a.rootnode.someothernode.othernodeyouwantochange = 'new data'
$a > newfile.xml

it probably won't run but get you started

Is there something I have to load / register for the [xml] stuff?

get-contents (according to | get-member) returns only a string, and I
can't find anything about xml using help

thanks!

$a = [xml]get-content myfile.xml

Should be:

$a = [xml] (get-content myfile.xml)

Hi, here are some more examples and a little explanation:

PS>$var = [sometype] somevalue

works like the cast operator in other languages.
So you can do things like this:

PS> [int] "5"
5

PS> [string] 5
5

PS> [double] "3.14159265358979"
3.14159265358979

PS> [int] 3.14159265358979
3

PS> [wmiclass] "Win32_DiskDrive"

Win32_DiskDrive

PS> $hwxml = [xml] "<hello>world</hello>"
PS> $hwxml

hello
-----
world

It is important to note that "int", "double", "string", "wmiclass", "xml"
etc. are basically just aliases for the real .NET types:

System.Int32
System.Double
System.String
System.Xml.XmlDocument
System.Management.ManagementClass#ROOT\cimv2\Win32_DiskDrive
etc.

Also you should know that you can ommit "System." so that [Int32] and
[Xml.XmlDocument] would also be correct.
Many usefull .NET assemblies like System.XML are loaded by default. To load
your own assemblies you can use the following command as a template:

[Reflection.Assembly]::LoadFrom("C:\PoSh\Example.Test.dll")

Now it all makes sense - and it even works! :-)
