I'd like a method that has the following API:
//get all users with a role of admin
var users = myRepository.GetUsers(u => u.Role == Role.Admin);

I am wondering if there is a method to check certain parts of a custom java class to see if it matches a certain criteria.

child(X) X is a child

How can I reverse a predicate's return value, and remove the elements that return false instead of true?
Here is my code:

(please ignore lack of erase)
with FindName a simple functor:

I would like to construct an XPath query that will return a "div" or "table" element, so long as it has a descendant containing the text "abc". The one caveat is that it can not have any div or table descendants.
<div>

<form>
<div>
<span>
<p>abcdefg</p>
