There has been a lot of discussions on View-engines for ASP.NET MVC and some criticisms against the inline "tag-soup" with for-loops and thing like it. The alternative or complement has been to use HTML-helpers, which are just inline method-calls. When I look inside ASP.NET MVC's HTML-helpers today they are using a class called TagBuil...
My question is essentially a simple one, though I'm looking for as in-depth an answer possible here: how does LINQ to XML work behind the scenes? Now, I have had a fair amount of experience working with LINQ to XML for various applications, so it's interfaces is nothing strange to me, but I am quite clueless as to how the internals oper...

I am trying to load this string data into an XDocument (System.Xml.Linq.XDocument), and then from there do some XML Magic and create an xlsx file for a report on the data.

We're storing out database definition as XML in the format at the end of this question. The problem I'm having is getting a list of schemas, the tables in those schemas, the columns in those tables (all with their associated information). My current code (included below the sample XML) grabs everything, completely ignoring nesting and, d...
Basically if I do Xdoc.Load(filename), do some changes then do Xdoc.Save(filename) does it only save things that changed such as inserted or removed elements, etc, or does it resave everything? Depending on the answer I'm thinking of determining whether my app is going to save per-change or save on explicit save and on exit. Also consi...

Unit testing my serialization code I found one failed because I had attributes listed in a different order (I'm just comparing the XDocument.ToString() values) and while I could fix that, it really doesn't matter to me in what order the elements or attributes appear as long as they're all there with the right name at the right level of h...
