NAME
XML::Parser::Lite - Lightweight regexp-based XML parser
SYNOPSIS
use XML::Parser::Lite;
$p1 = new XML::Parser::Lite;
$p1->setHandlers(
Start => sub { shift; print "start: @_\n" },
Char => sub { shift; print "char: @_\n" },
End => sub { shift; print "end: @_\n" },
);
$p1->parse('Hello World!');
$p2 = new XML::Parser::Lite
Handlers => {
Start => sub { shift; print "start: @_\n" },
Char => sub { shift; print "char: @_\n" },
End => sub { shift; print "end: @_\n" },
}
;
$p2->parse('Hello cruel World!');
DESCRIPTION
This Perl implements an XML parser with a interface similar to
XML::Parser. Though not all callbacks are supported, you should be able
to use it in the same way you use XML::Parser. Due to using experimental
regexp features it'll work only on Perl 5.6 and above and may behave
differently on different platforms.
Note that you cannot use regular expressions or split in callbacks. This
is due to a limitation of perl's regular expression implementation
(which is not re-entrant).
SUBROUTINES/METHODS
new
Constructor.
As (almost) all SOAP::Lite constructors, new() returns the object called
on when called as object method. This means that the following
effectively is a no-op if $obj is a object:
$obj = $obj->new();
New accepts a single named parameter, "Handlers" with a hash ref as
value:
my $parser = XML::Parser::Lite->new(
Handlers => {
Start => sub { shift; print "start: @_\n" },
Char => sub { shift; print "char: @_\n" },
End => sub { shift; print "end: @_\n" },
}
);
The handlers given will be passed to setHandlers.
setHandlers
Sets (or resets) the parsing handlers. Accepts a hash with the handler
names and handler code references as parameters. Passing "undef" instead
of a code reference replaces the handler by a no-op.
The following handlers can be set:
Init
Start
Char
End
Final
All other handlers are ignored.
Calling setHandlers without parameters resets all handlers to no-ops.
parse
Parses the XML given. In contrast to XML::Parser's parse method, parse()
only parses strings.
Handler methods
Init
Called before parsing starts. You should perform any necessary
initializations in Init.
Start
Called at the start of each XML node. See XML::Parser for details.
Char
Called for each character sequence. May be called multiple times for the
characters contained in an XML node (even for every single character).
Your implementation has to make sure that it captures all characters.
End
Called at the end of each XML node. See XML::Parser for details
Comment
See XML::Parser for details
XMLDecl
See XML::Parser for details
Doctype
See XML::Parser for details
Final
Called at the end of the parsing process. You should perform any
necessary cleanup here.
