Based on date, get todays and the next two days values from XML?

Question

Goal: Based on todays date and month, get actual and the next two days values from XML.

Issue: Although my c.Attribute(\"Day\").Value changes, my c.Attribute(\"Month\").

I would suggest you change your "model" class to use DateTime instead of string for the date. Transform all the elements into your model class, and then filter. It'll be a lot simpler than trying to do arithmetic based on the attributes.

Also note that using the explicit conversions from XAttribute is simpler than calling int.Parse everywhere. I would actually suggest creating a static FromXElement method in your model class, so you can write:

DateTime start = DateTime.Today;
// We'll use this as an *exclusive* upper bound
DateTime end = start.AddDays(3);

var query = from c in loadedCustomData.Descendants("PrayerTime")
            let bonn = Bønn.FromXElement(c)
            where bonn.Dato >= start && bonn.Dato < end;
            select bonn;

Or in extension method syntax:

// start and end as before
var query = loadedCustomData.Descendants("PrayerTime")
                .Select(c => Bønn.FromXElement(c))
                .Where(bonn => bonn.Dato >= start && bonn.Dato < end);
