Question

关于此Target-Url德国学校数据库http://192.68.214.70/km/asps/schulsuche.asp?q=a&a=100&s=1750

这个目标网址有一个网格（或表格） - 我有一个运行良好的代码 - 但它无法处理网格......

它会像以下那样吐出数据......

这很糟糕 - 我需要一个分隔符 - 我怎么能在结果中得到一些分隔符 - 或者逗号或标签....？

这里是代码：

  #!/usr/bin/perl
    use strict;
    use warnings;
    use HTML::TableExtract;
    use LWP::Simple;
    use Cwd;
    use POSIX qw(strftime);
    my $te = HTML::TableExtract->new;
    my $total_records = 0;
    my $suchbegriffe = "e";
    my $treffer = 50;
    my $range = 0;
    my $url_to_process = "http://192.68.214.70/km/asps/schulsuche.asp?q=";
    my $processdir = "processing";
    my $counter = 50;
    my $displaydate = "";
    my $percent = 0;

    &workDir();
    chdir $processdir;
    &processURL();
    print "\nPress <enter> to continue\n";
    <>;
    $displaydate = strftime('%Y%m%d%H%M%S', localtime);
    open OUTFILE, ">webdata_for_$suchbegriffe\_$displaydate.txt";
    &processData();
    close OUTFILE;
    print "Finished processing $total_records records...\n";
    print "Processed data saved to $ENV{HOME}/$processdir/webdata_for_$suchbegriffe\_$displaydate.txt\n";
    unlink 'processing.html';
    die "\n";

    sub processURL() {
    print "\nProcessing $url_to_process$suchbegriffe&a=$treffer&s=$range\n";
    getstore("$url_to_process$suchbegriffe&a=$treffer&s=$range", 'tempfile.html') or die 'Unable to get page';

       while( <tempfile.html> ) {
          open( FH, "$_" ) or die;
          while( <FH> ) {
             if( $_ =~ /^.*?(Treffer <b>)(d+)( - )(d+)(</b> w+ w+ <b>)(d+).*/ ) {
                $total_records = $6;
                print "Total records to process is $total_records\n";
                }
             }
             close FH;
       }
       unlink 'tempfile.html';
    }

    sub processData() {
       while ( $range <= $total_records) {
          getstore("$url_to_process$suchbegriffe&a=$treffer&s=$range", 'processing.html') or die 'Unable to get page';
          $te->parse_file('processing.html');
          my ($table) = $te->tables;
          for my $row ( $table->rows ) {
             cleanup(@$row);
             print OUTFILE "@$row\n";
          }
          $| = 1; 
          print "Processed records $range to $counter";
          print "\r";
          $counter = $counter + 50;
          $range = $range + 50;
          $te = HTML::TableExtract->new;
       }
    }

    sub cleanup() {
       for ( @_ ) {
          s/s+/ /g;
       }
    }

    sub workDir() {
    # Use home directory to process data
    chdir or die "$!";
    if ( ! -d $processdir ) {
       mkdir ("$ENV{HOME}/$processdir", 0755) or die "Cannot make directory $processdir: $!";
       }
    }

btw - 请参阅分隔符的一个示例......：

my @cols = qw(
    rownum
    number
    name
    phone
    type
    website
);

my @fields = qw(
    rownum
    number
    name
    street
    postal
    town
    phone
    fax
    type
    website
);

注意：这篇文章来自用户，它给了我一些关于这个帖子的一些很好的提示。看到 HTML::TableExtract: how to run the right argument [see live example]

嗯 - 我想将这些想法迁移到上面提到的蜘蛛和解析器中。这有可能。你可以给我一些提示，如何添加一些代码行 - 这样结果就会在csv-formate中吐出......！

任何和所有帮助将不胜感激..

更新：我做了一些试验：

这里有什么问题......？

Answer 1

您应该使用Text::CSV来构建输出，这样可以省去尝试手动处理嵌入式引号和分隔符的麻烦。因此，使用您想要的选项创建Text::CSV的实例并替换它：

print OUTFILE "@$row\n";

与

$csv->combine(@$row);
print OUTFILE $csv->string();

$csv是Text::CSV个实例。

此外，您的cleanup功能有点破碎，它应如下所示：

sub cleanup {
   for ( @_ ) {
      s/\s+/ /g;
   }
}

当您粘贴代码时，丢失的\可能只是一个错字。但

不要使用原型，他们不会做你认为他们做的事情。你说的地方：

sub cleanup() {

只是说

sub cleanup {

并且不要使用前导符号调用函数（即不要&workDir();，只需要workDir();），除非你知道它的副作用是什么。
