How to create a SPUser object from its XML representation

Question

I have the following XML representation for a user:

  <pc:Person xmlns:pc="http://schemas.microsoft.com/office/infopath/2007/PartnerControls">
    <pc:DisplayName>John Dodo</pc:DisplayName>
    <pc:AccountId>DOMAIN\john.dodo</pc:AccountId>
    <pc:AccountType>User</pc:AccountType>
  </pc:Person>

How can I convert this to a SPUser object?

I don't want to parse the XML for this so I guess there is a standard way to do it but could not find how.

(I'm using SharePoint 2010 if that counts)

As far as I know you will have to parse the XML. Its very easy to do

        string xml = @"<pc:Person xmlns:pc=""http://schemas.microsoft.com/office/infopath/2007/PartnerControls""> 
                        <pc:DisplayName>John Dodo</pc:DisplayName> 
                        <pc:AccountId>DOMAIN\john.dodo</pc:AccountId> 
                        <pc:AccountType>User</pc:AccountType> 
                       </pc:Person>";

        var ns = "{http://schemas.microsoft.com/office/infopath/2007/PartnerControls}";

        var doc = XDocument.Parse(xml);

        var loginName = doc.Descendants(ns + "AccountId").FirstOrDefault().Value;

        using (SPSite site = new SPSite("http://SiteCollectionURL"))
        {
            using (SPWeb web = site.OpenWeb())
            {
                SPUser user = web.AllUsers[loginName];
            }
        }
