Perl 中的相对记录分隔符
我有一个看起来像这样的数据:
id:40108689 --
chr22_scrambled_bysegments:10762459:F : chr22:17852459:F (1.0),
id:40108116 --
chr22_scrambled_bysegments:25375481:F : chr22_scrambled_bysegments:25375481:F (1.0),
chr22_scrambled_bysegments:25375481:F : chr22:19380919:F (1.0),
id:1 --
chr22:21133765:F : chr22:21133765:F (0.0),
所以每条记录都由 id:[somenumber] -- 分隔
访问数据的方法是什么,以便我们可以获得数组的哈希值:
$VAR = { 'id:40108689' => [' chr22_scrambled_bysegments:10762459:F : chr22:17852459:F (1.0),'],
'id:40108116' => ['chr22_scrambled_bysegments:25375481:F :chr22_scrambled_bysegments:25375481:F (1.0)',
'chr22_scrambled_bysegments:25375481:F : chr22:19380919:F (1.0),'
#...etc
}
我尝试接近这使用记录分隔符。但不确定如何概括它?
{
local $/ = " --\n"; # How to include variable content id:[number] ?
while ($content = <INFILE>) {
chomp $content;
print "$content\n" if $content; # Skip empty records
}
}
I have a data that looks like this:
id:40108689 --
chr22_scrambled_bysegments:10762459:F : chr22:17852459:F (1.0),
id:40108116 --
chr22_scrambled_bysegments:25375481:F : chr22_scrambled_bysegments:25375481:F (1.0),
chr22_scrambled_bysegments:25375481:F : chr22:19380919:F (1.0),
id:1 --
chr22:21133765:F : chr22:21133765:F (0.0),
So each record is separated by id:[somenumber] --
What's the way to access the data so that we can have a hash of array:
$VAR = { 'id:40108689' => [' chr22_scrambled_bysegments:10762459:F : chr22:17852459:F (1.0),'],
'id:40108116' => ['chr22_scrambled_bysegments:25375481:F :chr22_scrambled_bysegments:25375481:F (1.0)',
'chr22_scrambled_bysegments:25375481:F : chr22:19380919:F (1.0),'
#...etc
}
I tried to approach this using record separator. But not sure how to generalize it?
{
local $/ = " --\n"; # How to include variable content id:[number] ?
while ($content = <INFILE>) {
chomp $content;
print "$content\n" if $content; # Skip empty records
}
}

使用普通的记录分隔符。
使用 $last_id 跟踪遇到的最后一个 id 行,并在遇到另一行时设置为下一个 id。将非 id 行推送到数组中,以获取最后一个匹配的 id 行的哈希键。
Uses the normal record separator.
Uses $last_id to keep track of the last id row encountered and is set to the next id when another one is encountered. Pushes non-id rows on to an array for the hash key of the last matched id line.
