Maximum recursion depth

See original GitHub issue

New Feature Proposal

Description

Add possibility to restrict recursion depth to a maximum number.

Background

We use AngleSharp to parse E-Mails. Those can come from good people and from bad (Spam). In the latter case, the E-Mails often contain invalid tags and invalid HTML. Currently we run into issues with following stuff:

<div></div><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV="">
<div></div><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV=""><D IV="">

And this is only a small piece. The original email is about ten times longer. This one leads to a StackOverflow in CollectionExtensions.GetAllElements<T>(this INode parent, Predicate<T> predicate) while accessing child nodes.

Of course I know that the maximum depth depends on several factors, e.g. from where the code is called and how much is on the stack.

Any other suggestions to solve this issue?

//Edit: maybe we are able to use a iterative solution instead of a recursive one. Are there any reasons for the current choice?
