Re: Caching Entities with XML::LibXML

I think to prevent XML::LibXML from loading external entities, you can pass load_ext_dtd => 0 in the constructor. That will stop you from hammering w3.org, but I think it will also somewhat hamper validation, if that's your aim.

I'm not doing any validation. Getting the entities is required for parsing. Preventing the fetching of the remote DTD without adding something in its place prevents parsing. `use strict; use warnings; use XML::LibXML qw( ); my $parser = XML::LibXML->new( load_ext_dtd => 0, ); my $xhtml = <<'__EOI__'; <?xml version="1.0" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Test</title> </head> <body> </body> </html> __EOI__ $parser->parse_string($xhtml);` [download] `:8: parser error : Entity 'nbsp' not defined <body> </body> ^` [download]	[reply] [d/l] [select]
