How to add child where parent element's attribute = x

I have an XML document with the following structure:

<position index="x">
     <character>y</character>
</position>

I need to be able to add a new character to a position based on its index. For example, where index = "3", add the character "g".

I know I can find an element with the following:

var query = from positions in myDoc.Descendants("position")
     where (string)positions.Attribute("index").Value == n
     select positions;

But I'm having trouble figuring out if I need a similar kind of query or construction to identify an element with attribute value x, then add child nodes.

Your query already returns elements you want to add to, so it boils down to:

var query = from positions in myDoc.Descendants("position")
            where (string)positions.Attribute("index").Value == n
            select positions;
foreach (var position in query)
{
    position.Add(new XElement("character", "g"));
}
