Answer 1

I finally figured it out after I looked at Windows Runtime Xml data API sample.

    public override async Load()
    {
        var file = await GetPackagedFile("assets", "world.xml");
        LoadXml(file);
    }

    private async void LoadXml(StorageFile file)
    {
        XmlLoadSettings settings = new XmlLoadSettings() { ValidateOnParse = false };
        XmlDocument xmlDoc = await XmlDocument.LoadFromFileAsync(file, settings);

        foreach (IXmlNode xmlNode in xmlDoc.ChildNodes)
        {
            //ProcessNode(xmlNode);
        }
    }

    private async Task<StorageFile> GetPackagedFile(string folderName, string fileName)
    {
        StorageFolder installFolder = Windows.ApplicationModel.Package.Current.InstalledLocation;

        if (folderName != null)
        {
            StorageFolder subFolder = await installFolder.GetFolderAsync(folderName);
            return await subFolder.GetFileAsync(fileName);
        }
        else
        {
            return await installFolder.GetFileAsync(fileName);
        }
    }
}
