phpでjuniper SSG5のコンフィグファイルを解析（配列化）する

業務自動化で必要になってくるものと思い作りました。

適当に作ったので無駄なことが多いかもしれませんが、とりあえず投稿してブラシュアップできたらと思います。
またあまりphpのクラス作成にもなれてないのでお作法ができていないと思われます。

SSG５設定コマンドのスペース区切りを階層と考えて、XMLファイルでコマンド階層のパスを追っていく仕組みにすることで、他の製品のコマンドにも応用できるプログラム作成ができるようになればと考え作りました。（実際は難しいですが土台くらいは同じ仕様にできそうな気がしてます。）

使い方(SsgPaser.php)

<?php
include_once "SsgPaser.php";


$ssg = new SsgPaser;

//コンフィグファイルを指定する
$configfile = "d:¥cfg.txt";
$ssg->setFilename($configfile);

//コンフィグファイルを解析する
$ssg->convertAllArray();

//アドレスオブジェクトの一覧取得（配列）
$address = $ssg->getAddressRaw();

//ポリシーの一覧取得（配列）
$policy = $ssg->getPolicyRaw();
