没有从 HTML::TreeBuilder 获得输出

Question

我正在尝试从大约 3,000 个 HTML 文件中获取一大堆值并将它们保存到电子表格中。

我正在使用 HTML::TreeBuilder 处理 HTML 并使用创建电子表格 Spreadsheet::WriteExcel.

但我的脚本没有成功获取值。我明白了

在电子表格第 63 行的连接 (.) 或字符串中使用未初始化的值 $val。

我可能做错了什么？

这是my HTML files on pastebin.com 的示例。问题太大，无法发布。

Answer 1

您可能可以减少代码。即使在下面的示例中我没有使用 HTML::TreeBuidler，方法也是类似的。使用Mojo::DOM58，

use 5.014;
use warnings;

use Mojo::DOM58;
use Path::Tiny;
use Data::Dumper;

my @fields = qw( TeamName TeamNumber SchoolName Area District Phone Phone2 Fax Address1 Address2 City State Zip Website );

my $html = path('team.html')->slurp;
my $dom = Mojo::DOM58->new($html);

my $data;
for my $field( @fields ) {
    $data->{$field} = $dom->at(qq{input[name*="txt_$field"]})->attr('value') // "";
}

say Dumper $data;

打印：

$VAR1 = {
          'TeamName' => 'Ruidoso',
          'Zip' => '',
          'State' => 'NM',
          'City' => '',
          'District' => '1',
          'Phone2' => '',
          'Area' => '1',
          'SchoolName' => '',
          'Address2' => '',
          'Website' => '',
          'Address1' => '',
          'Phone' => '',
          'Fax' => '',
          'TeamNumber' => '83'
        };

Answer 2

简而言之，其中一些'name' 可能只是在（某些）HTML 文件中找不到。所以先测试看看它是否在那里，然后写信给$val或打印关于它没有找到的消息。

最明显的需要改进的是：不需要单独的功能。您可以一次调用搜索并找到所有这些，并将它们存储在返回的哈希name => value中。

sub getNames {
    my ($file) = @_;
    my $tree = HTML::TreeBuilder->new_from_content( path($file) );
    my @nodes = $tree->look_down(_tag => 'input');

    # List phrases to find, and build hash with their derived names
    # Should probably be defined globally, once for the whole program
    my @patterns  = map { '$txt_' . $_ } 
        qw(TeamName TeamNumber SchoolName Area District 
           Phone Phone2 Fax Address1 Address2 City State Zip Website);

    # Name for each pattern: everything after first _ (so after $txt_) 
    my %patt_name = map { $_ => (/[^_]+_(.*)/)[0] } @patterns;
    my %name_val;
    foreach my $node (@nodes) {
        foreach my $patt (@patterns) {
            my $name = $node->look_down('name', qr/\Q$patt/);
            if ($name) {
                $name_val{$patt_name{$patt}} = $name->attr('value') || '';
            }
        }
    }

    # Name and Email are stored differently. Fetch those now
    my ($table) = $tree->look_down(_tag => 'table', class => 'rgMasterTable');
    for my $tr ( $table->look_down(_tag => 'tr') ) { 
        next unless my @td = $tr->look_down(_tag => 'td');
        # Discard incomplete Name-Email records -- either both or none
        if (2 == grep { not ref $_ } @td) {
            @name_val{qw(Name Email)} = map { $_->as_trimmed_text } @td[0,1];
        }
        else { @name_val{qw(Name Email)} = ('', '') }
    }
    return \%name_val;
}

对于Name 和Email，我们要求两者都作为文本存在，或者两者都被丢弃。 （示例源在div 中包含There are no people ... 用于Name，而没有用于Email。）

要得到任何东西，而不是上面的if-else

@name_val{qw(Name Email)} = 
    map { (defined) ? $_->as_trimmed_text : '' } @td[0,1];

我们得到上面引用的Name 的注释和Email 的空字符串，带有这个示例。

然后

# Specify spreadsheet headers in desired order and write  to file
my @headers = ('Name', 'Email', 'Team Number', 'Team Name', ...);
$worksheet->write_row(0, 0, \@headers);               # first row

# Build ancillary data structures to later sort results by this order
# each header with its index from @headers (specifies columns' order)
my %ho = map { state $idx; $_ => ++$idx } @headers;
# each name (`TeamNumber` ...) with the index of its header
my %name_order = ( Name => $ho{Name}, Email => $ho{Email}, 
    TeamNumber => $ho{'Team Number'}, TeamName => $ho{'Team Name'}, ... 
);

my $row = 1;
foreach my $file (@files) {
    next if -d $file;

    my %name_val = %{ getNames($file) };
    fill_row($worksheet, $row++, \%name_val, \%name_order);

    foreach my $name (sort keys %name_val) {  # demo
        if ($name_val{$name}) { print "$name => $name_val{$name}\n" }
        else                  { print "Not found $name in $file\n" }
    }
}

sub fill_row {
   my ($ws, $row, $rdata, $rorder) = @_;    
   my %name_val   = %$rdata;
   my %name_order = %$rorder;

   my @vals = map { $name_val{$_} } 
              sort { $name_order{$a} <=> $name_order{$b} } 
              keys %name_val;

   $ws->write_row($row, 0, \@vals);  # add check (returns 0 on success)

   return 1;
}

write_row 引用一个数组并写出一行 它的元素。请注意，write 也可以在给出 arrayref 时使用。

链接的 HTML 文件的输出

面积 => 1 区 => 1 状态 => NM TeamName => Ruidoso 团队编号 => 83

和Not found ... 为其他人。 .xls 文件是正确的（使用完整的名称列表时）。

这是一个完整的程序，带有提供的示例 HTML 源代码。

另外：一个实际的页面可能有多个名称-电子邮件对

use LWP::Simple qw(get);

sub getNames {
    my ($file) = @_; 
    my $url = 'https://www.judgingcard.com/Directory/Directory.aspx?ID=1643';
    my $page = get($url) or die "Can't get the page $url: $!";
    my $tree = HTML::TreeBuilder->new_from_content( $page );

    my @nodes = $tree->look_down(_tag => 'input');

    my @patterns = map { '$txt_' . $_ } @src;
    # List phrases to find, and build hash with their derived names
    # Name for each pattern: everything first _ (so after \$txt_)
    my %patt_name = map { $_ => (/[^_]+_(.*)/)[0] } @patterns;

    my %name_val;
    foreach my $node (@nodes) {
        foreach my $patt (@patterns) {
            my $name = $node->look_down('name', qr/\Q$patt/) or next;
            $name_val{$patt_name{$patt}} = $name->attr('value') // ''; 
        }   
    }   

    # Name and Email are stored differently, fetch those now
    my %name_email;
    my ($table) = $tree->look_down(_tag => 'table', class => 'rgMasterTable');
    for my $tr ( $table->look_down(_tag => 'tr') ) { 
        next unless my @td = $tr->look_down(_tag => 'td');
        # There may be more than one Name-Email pair
        # so enter key-value pair explicitely
        if (2 <= grep { ref } @td) {
            $name_email{$td[0]->as_trimmed_text} = $td[1]->as_trimmed_text;
        }
        else { %name_email = ('', '') }
    }
    return \%name_val, \%name_email;
}

那么主要是你需要的

foreach my $file (@files) {
    next if -d $file;

    # Parse the file, unpack name-value and name-email hashes
    my ($rname_val, $rname_email) = getNames($file);
    my %name_val   = %$rname_val;
    my %name_email = %$rname_email;

    # Print a row for each Name-Email, adding them to %name_val
    foreach my $name (keys %name_email) {
        $name_val{Name}  = $name;
        $name_val{Email} = $name_email{$name};
        fill_row($worksheet, $row++, \%name_val, \%name_order);
    }
}

具有多个名称-电子邮件对的所需格式是：相同的标题，并且对于每一对，将单独的行打印到文件中，其中除名称-电子邮件之外的所有信息都是相同的。
