I have 2 questions for 2 different things, but I thought it'd be better to ask both on same thread than split them into 2 threads.

First, is there a nice way to access the first child of a folder/page/etc.

Example:
Root
--Folder1
----Page1
----Page2
----Page3
--Folder2

I want to acces the page1 node throught the Folder1 node. I want to select the first node (first child) in the list (from Folder1) and then get the values I need from it.

Secondly, I wanted to know if there is a way to do SQL-Like request on document type properties. In fact, I have various document types with a same part of property (they all contains "Title" in the property name, ex: ArticleTitle) and a if/else is not the best way to do in case they add a new document type, it won't be considered until I change it.

I wanted to know if there is a way I can obtain it like:

string[] myProperty = node.SearchProperties("Title"); // Obtains "ArticleTitle"
node.getValue(myProperty[0]);

Or something like that...

Thanks!
