Subject: Adding processing instructions
Download (untitled) / with headers
text/plain 700b
How would it fit the general design if it was possible to add processing instructions using the configuration hash? I'd really like if i could do something like this: my $generator = XML::Generator::PerlData->new( Handler => $builder, pi => { xml => {version => '1.0', encoding => 'UTF-8'}, 'xml-stylesheet' => {type => 'text/xsl', href => 'my.xsl'} } ); Which would then later generate the processing instructions <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="my.xsl"?> It could also be some kind of general solution where some parts of the perl data structure is mapped to processing instructions.

Strictly speaking, your example doesn't contain two PIs, it contains one XML declaration and one processing instruction. (two different entities with two separate SAX methods for parsing/generation). If Generator::PerlData isn't reliably generating an XML declaration then that's a bug that needs fixing wholly apart from this feature request. That said, yes, I'd be happy to add a processing_instructions option to the constructor that would behave as you expect for the 'stylesheet' PI. Ticket accepted.

Well - I could imagine times where you'd like to use XML::Generator::PerlData to generate XML fragments to embed in larger documents, which wouldn't be possible if it always emits an XML declaration. Show quoted text

Just a single stylesheet parameter could do the trick for me. Show quoted text

Great! Thanks! Please let me know if you need anything from me. Regards, Michael.

Hey Michael, I stole a few minutes to add the processing_instruction option. If you have a sec, you can snag a pre-release version from GitHub here: git://github.com/ubu/xml-generator-perldata.git Give it a spin, and see if it does what you need/expect. -kip
