我如何將它插入散列？

我新的Perl和IM試圖插入一些數據散列，但卡住，幫助表示讚賞....我如何將它插入散列？

現在我要如何插入到這散列

方式Im做是

%hash = map {chomp ; split /\s+=\s+[0-9]/} (@dblst);

其中dblst是包含數據的陣列

當我這樣做即時得到

你看到一些數字是在左邊，我希望所有的數字到右側，這樣我想與哈希執行一些算術運算...幫助是讚賞

你的問題是你正在使用的正則表達式，和無限的分裂。由於您只查找關鍵字和值，因此您應該（可能）將分隔限制爲兩個字段。如果你應該有一個字段分裂成更少或更多的字段，你的散列分配將被破壞。你也應該只在分隔符上分割，這是一個被空白包圍的等號。

你的正則表達式：

/\s+=\s+[0-9]/

將分裂的「空白後跟一個等號後面的空格後面跟着一個數字」。該數字將被刪除。假設一條線如foo = 0，那麼您將得到結果列表"foo", ""。

你需要的是：

split /\s*=\s*/, $_, 2;

這會剝奪等號周圍的任何空白，並且只返回最多兩個字段（key和value，大概）的。你仍然會發現一些領域包含領先的空白，但我認爲這是可以接受的。

使用map語句的缺點是它返回一個完整的列表，正如您看到列表可能會損壞一樣。一個更明智的方法是使用一個for循環：

my %hash; 
for (@dblst) { 
    chomp; 
    my ($key, $val) = split /\s*=\s*/, $_, 2; 
    $hash{$key} = $val; 
}

有了這個代碼，也容易插入控制語句，防止空白鍵/值的插入，防止重複，做其他各種測試你想。

它工作的感謝人，我認爲我應該在處理這種文件時處理正則表達式 – mviswa 2013-02-23 16:01:03

@mViswa沒有比在真實世界的數據上嘗試它們更好的方式來訓練正則表達式。一定要使用'使用警告;嚴格使用;'，因爲它們將提供寶貴的幫助。此外，您知道您可以通過點擊旁邊的複選標記來接受您的問題的答案。 – TLP 2013-02-23 16:05:38

非常感謝很多人，根據您的建議不客氣 – mviswa 2013-02-23 16:10:20

我如何將它插入散列？
