Yes, but I don't think dxml support these features.

It does not. Those features come under the big bad guys feature list.

Gonna have to go to C for it.

Surely that means you can use Python, Rust, C++, or D rather than
having to descend to using C?

libxml2 is definitely usable from Python, it must be usable from D. Of
course, I am assuming libxml2 has the facilities required.

libxml2 is precisely what I meant.

We just don't have the libraries written in D at this point.

There are situations where you create a binding in preference to
writing something from scratch. cf. gtk, gstreamer, etc. so why not
libxml2?

I am suggesting a binding. I think we have our wires crossed on this.

Apparently, bindings to libxml2 existed back in 2008.

If I were interested in XML processing yes I would. However, just at
the moment I am doing things with MPEG-TS and gstreamer-rs. I may
investigate the analogue for GstreamerD.

On the other hand there are enough people moaning about std.xml and the
general lack of quality, high performance D support for XML that there
is clearly a lot of people who should be interested in creating a D
binding to libxml2.

The problem is that while there is no shortage of complaints about XML
support in D, there is a great dearth of people actually willing to *do*
something about it.

At least Jonathan wrote dxml, which arguably would meet the need in most
cases.  So there's that.  But if somebody wants entity references and
other similar things, the only recourse would appear to be to wrap
libxml2.  Given D's aptitude at interfacing with C, this should be much
simpler than writing dxml.  It just needs someone to sit down and *do*
it.

I am trying to port libxml++ to D.
I use dstep to generate the binding to libxml2, and then porting 
c++ to D.
But I don't have much time, and there are some failures with 
dstep. I don't have a computer at home, so I must use termux to 
coding. I hope someone can continue to maintaining the android 
port of ldc.

In my case it is because I have no need to deal with XML using D, and I am =

in the market for paid work. Those actually doing stuff with XML and D have
far fewer excuses.

That people who have the problem can write many lengthy emails on the D lis=

rather than doing something about creating a D binding to libxml2 is clearl=

the bulk of the problem.
