i've created a module, part of which creates the beginning of a web page. the module overall works fine. the sub in question even works fine, except for one point. here's the sub in the module:sub html_start { my %options = @_; # $options{title} = page title my $page_start = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\";> <html xmlns=\"http://www.w3.org/1999/xhtml\"; lang=\"en\" xml:lang=\"en\"> <head> <title>$options{title}</title> <link href=\"/css/style1.css\" rel=\"stylesheet\" type=\"text/css\" /> </head> "; return($page_start); } # end of sub html_start below is the code fragment calling the sub: ###### my $page_start = &html_start(title => "Privacy"); print " $page_start <head> </head> . . . </html> ###### notice the additional empty <head> tags.
Noticed.
this works fine and gives "Privacy" and the page title. removing those tags causes the page code to be printed out when retrieving the page.
I don't understand that. For me things are printed out only when I use the print() function.
my question: why do the <head> tags in the sub work and the page display perfectly with the additional empty <head> tags, yet only print out the code as ascii output when i remove the 2nd set of <head> tags?
Consequently, that question is incomprehensible to me.
why are the <head> tags in the sub not considered legitimate html code when the <head> structures are identical in both the sub and the main code?
If that is true, you'd better ask W3C. It has nothing to do with Perl. -- Gunnar Hjalmarsson Email: http://www.gunnar.cc/cgi-bin/contact.pl -- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] http://learn.perl.org/
