Get XML from String (not file)

I have a PowerShell script:

$xmlString="<root>
        <section>
            <node id='1'>AAA</node>
            <node id='2'>BBB</node>
            <node id='3'>CCC</node>
        </section>
    </root>"

$xml = New-Object -TypeName System.Xml.XmlDocument
$content = $xml.LoadXml($xmlString)

Value of $content is null

Inner Exception in $xml variable is <Error retrieving property - ArgumentException>

I have checked whether string starts with [System.Text.Encoding]::UTF8.GetPreamble() but it does not.

Can you please tell, what it is correct way to convert such string to XML?

You can directly cast the string to XmlDocument like this:

[xml]$xmlString="<root>
        <section>
            <node id='1'>AAA</node>
            <node id='2'>BBB</node>
            <node id='3'>CCC</node>
        </section>
    </root>"

If you want to keep the format of the variable, you can ofc just do it like this:

$xmlString="<root>
        <section>
            <node id='1'>AAA</node>
            <node id='2'>BBB</node>
            <node id='3'>CCC</node>
        </section>
    </root>"

[xml]$content = $xmlString

To follow up on @AnsgarWiechers comment, if you really want to use LoadXML, this is how it should look:

$xmlString=
"<root>
        <section>
            <node id='1'>AAA</node>
            <node id='2'>BBB</node>
            <node id='3'>CCC</node>
        </section>
</root>"

$xml = New-Object -TypeName System.Xml.XmlDocument
$xml.LoadXml($xmlString)

LoadXml will load a value from the given string to the $xml variable that calls the method.

It doesn't return any value, but saves it to $xml.

ConvertFrom-Xml is what you need!

It's available from the PowerShell Gallery as part of Avande.CoolFunctions

$xmlString = @"
<root>
    <section>
        <node id='1'>AAA</node>
        <node id='2'>BBB</node>
        <node id='3'>CCC</node>
    </section>
</root>
"@

$xmlString | ConvertFrom-Xml
