I refined my attempt a little further, and the following code does
seem to work, however it has 2 major problems:
1. Very limited support for XPath features
Basic paths are supported for elements, attributes, ".", and "..",
plus also the "" predicate format is supported -
however, only one predicate per path step is supported, and expr must
be a relative path.
2. Poor performance

Hello all,
I was wondering if someone can give me some tips on this problem.
I'm trying to take content of a queue (Xqueue) and copy it into another
queue (Yqueue)
I tried using a while and/or for loop.
for example if queue X contains numbers (3,5,8,6)
I want to copy number (3,5) into queue Y, then I want to delete number 8

I am not sure if this is something that is covered by the Standard, or
if it's an implementation detail of my Standard Library.
I am reading in a large amount of data into a std::set. There is an
overload for std::set::insert() that takes in an iterator as a hint as
to where the new value should be inserted, and my implementation
(Dinkumware) says that if the hint is good (meaning the iterator points
immediately before or after where...

Why does insert only work when specifying an iterator plus the object to
be inserted:
std::vector<intt;
std::vector<int>::iterator it;
it = t.begin();
t.insert(it,33);
If I use push_back instead I don't need to supply the iterator. But what

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
