NAME
XML::Parser::Style::Stream - Stream style for XML::Parser
SYNOPSIS
use XML::Parser;
my $p = XML::Parser->new(Style => 'Stream', Pkg => 'MySubs');
$p->parsefile('foo.xml');
{
package MySubs;
sub StartTag {
my ($e, $name) = @_;
# do something with start tags
}
sub EndTag {
my ($e, $name) = @_;
# do something with end tags
}
sub Characters {
my ($e, $data) = @_;
# do something with text nodes
}
}
DESCRIPTION
This style uses the Pkg option to find subs in a given package to call
for each event. If none of the subs that this style looks for is there,
then the effect of parsing with this style is to print a canonical copy
of the document without comments or declarations. All the subs receive
as their 1st parameter the Expat instance for the document they're
parsing.
It looks for the following routines:
• StartDocument
Called at the start of the parse .
• StartTag
Called for every start tag with a second parameter of the element
type. The $_ variable will contain a copy of the tag and the %_
variable will contain attribute values supplied for that element.
• EndTag
Called for every end tag with a second parameter of the element
type. The $_ variable will contain a copy of the end tag.
• Text
Called just before start or end tags with accumulated non-markup
text in the $_ variable.
• PI
Called for processing instructions. The $_ variable will contain a
copy of the PI and the target and data are sent as 2nd and 3rd
parameters respectively.
• EndDocument
Called at conclusion of the parse.
