Save XML formatted with tabs instead of spaces?

I’m creating some XML and saving it to a file via FileStream, but the child nodes are indented with 2 spaces. How can I reformat with tabs instead? I’m trying to write a recursive function to go through the xml and build the string I want, but then my question is: If I had the following XML…

<name>
  <first>Lisbeth</first>
  <last>Salander</last>
</name>

… how do I get the string “<first>Lisbeth</first>” instead of getting “Lisbeth”?
