Hello,

I am trying to parse some big xml files while not eating all the user memory, so XML::SAX::Parser seems to be the solution.

My files may contain different diacritics, so preserving the file utf-8 encoding is needed, but XML::SAX::ParserFactory (code taken from XML::SAX::Parser examples) is giving by default a parser that does not get the encoding from the document declaration.

I then discovered that there is more than one SAX parser on my system with 

#debug : list known parsers
my $parsers = XML::SAX->parsers();
say np $parsers;

[download]
and by accident while testing all of them, only XML::LibXML::SAX::Parser seems to be able to get the document encoding.

I wonder why not all parser implementation are able to give all the document properties and how I am supposed to know the differences but with trial and error...

Also, why do I need to use explicitly XML::LibXML::SAX::Parser while the documentation of XML::LibXML only tells about XML::LibXML::SAX that miss the Encoding attribute of the xml declaration?

The best programs are the ones written when the programmer is supposed to be working on something else. - Melinda Varian
