Need help building an XML document

[nbrege]

I need to build an XML document from data read in from a csv file. I want to store the main body of the document in a string as follows:

    Dim mainNode As String =
        "<?xml version=""1.0"" encoding=""UTF-8""?>
<Job>
  <ProductVersion>2022</ProductVersion>
  <Unit>mm</Unit>
  <Properties>
    <Job>
      <Information>
        <Job>
          <Name>Some Value</Name>
          <Description></Description>
        </Job>
      </Information>
      <Attributes>
        <Parameter>
          <Name>SI_UCS_Off</Name>
          <Description>++UCS's Off</Description>
          <Type>B</Type>
          <!--Measurement|Meas|M|Degrees|Deg|D|Integer|Int|I|Boolean|Bool|B|Decimal|Dec|D|Text|T|Currency|Cur|C-->
          <Value>1</Value>
          <Style>Note</Style>
          <!--Attribute|Note|Standard *standard is default if missing-->
        </Parameter>
      </Attributes>
    </Job>
  </Properties>

  <Rooms>
     ' insert sub-nodes here
  </Rooms>
</Job>"

I first need to fill in the <Name> node with a value. Then I want to define a sub-node as follows:

    Dim roomNode As String =
        "    <Room>
      <RoomProperties>
        <Room>
          <General>
            <Name>Some Value</Name>
          </General>
        </Room>
      </RoomProperties>
      <Order>
        <Assemblies>
            ' insert sub-nodes here
        </Assemblies>
      </Order>
    </Room>"

I need to set the <Name> node of this sub-node with a value, then insert the sub-node into the <Rooms> node of the main node.
Hopefully this makes sense. I'm not sure if I should use XmlDocument or XDocument. I'm hoping someone can help me get a start on this. I also need to add another sub-node under the <Assemblies> node, but if I can get help with the first part, I think I can figure it out. I haven't programmed in a few years so I'm a little rusty. Thanks...
