我有2個XML文件1 115MB大小,另一個爲34MB大小。解析大型XML文件?
Wiile讀取文件中的有1場稱爲遞減,與文件B的關係就在那裏我檢索文件B場id其中desc.file A是iqual到name.file B.
文件A已經太大,我不得不在文件B內搜索,並且需要很長時間才能完成。
我怎麼能加快這一proccess或什麼會是一個更好的計算策略做呢?
當前的代碼我使用:文件B.XML的
<?xml version="1.0" encoding="utf-16"?>

例如:文件A.XML的
#!/usr/bin/perl
use strict;

use XML::Simple qw(:strict XMLin);
my $npcs = XMLin('Client/client_npcs.xml', KeyAttr => { }, ForceArray => [ 'npc_client' ]);

my ($nameid,$rank);
open (my $fh, '>>', 'Output/npc_templates.xml');
print $fh "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<npc_templates xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:noNamespaceSchemaLocation=\"npcs.xsd\">\n";
foreach my $npc (@{ $npcs->{npc_client} }) {

if (defined $string->{name} && $string->{name} =~ /$npc->{desc}/i) {
$nameid = $string->{id};
last;
}
}
} else {

}
if (defined $npc->{hpgauge_level} && $npc->{hpgauge_level} > 25 && $npc->{hpgauge_level} < 28) {

} elsif (defined $npc->{hpgauge_level} && $npc->{hpgauge_level} > 10 && $npc->{hpgauge_level} < 15) {
$rank = 'ELITE';
} elsif (defined $npc->{hpgauge_level} && $npc->{hpgauge_level} > 0 && $npc->{hpgauge_level} < 11) {
$rank = 'NORMAL';
} else {

}
print $fh qq|\t<npc_template npc_id="$npc->{id}" name="$npc->{name}" name_id="$nameid" height="$npc->{scale}" rank="$rank" tribe="$npc->{tribe}" race="$npc->{race_type}" hp_gauge="$npc->{hpgauge_level}"/>\n|;
}
print $fh "</<npc_templates>";
close($fh);
例如
