A Perl module to parse an XML string by string?

Doctrin has asked for the wisdom of the Perl Monks concerning the following question:

Hello everyone! Could anyone tell if there is a Perl XML parser that reads input XML file string by string, not the whole at once?.. The reason of such question is - I have a real big XML, about 1G, and want Perl to find all "id" attributes of nodes with a particular path, say, "root/mynode":

<root>
blah-blah, some nodes here
<mynode id=500>
and some nodes here also
</mynode>
...
blah-blah, some nodes here
<mynode id=500>
and some nodes here also
</mynode>
</root>

Thanks in advance for your help P.S. Does XML::XPath do so?..

An example with XML::Rules `use XML::Rules; my $xml = <<XML; <root> <mynode id='500'> </mynode> <mynode id='500'> </mynode> </root> XML my @rules = ( # Only get 'mynode' directly under root mynode => [ '/root' => sub { print "$_[1]->{id}\n"; return }, _defau +lt => undef ], _default => undef, ); my $xr = XML::Rules->new(rules => \@rules); $xr->parse($xml);` [download]	[reply] [d/l]

You can use XML::LibXML::Reader. Note that your example XML is not well formed: attribute values must be enclosed in single or double quotes. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply]
