任务
用& nbsp;替换任何标签内容中的所有空格. y.html(示例文件) <p class=MsoNormal style='margin-top:1.0pt;margin-right:0cm;margin-bottom:1.0pt; margin-left:34.0pt;text-indent:-19.8pt'><span lang=NL-BE style='font-size:10.0pt; font-family:Symbol;color:black;mso-ansi-language:NL-BE'>·</span><span class=GramE><span style='font-size:7.0pt;color:black'> </span><span style='font-size:10.0pt;font-family:Arial;color:black'>Kit</span></span><span style='font-size:10.0pt;font-family:Arial;color:black'> </span><span class=SpellE><i><span style='font-size:10.0pt;font-family:Arial'>Strongyloides</span></i></span><i><span style='font-size:10.0pt;font-family:Arial'> <span class=SpellE>ratti</span></span></i><span style='font-size:10.0pt;font-family:Arial'> (nr. 9450) van <span class=SpellE>Bordier</span> Affinity Products. </span><span lang=NL-BE style='font-size:10.0pt;font-family: Arial;mso-ansi-language:NL-BE'>Zie bijsluiter in bijlage: CLKB_B_0306.

use strict;
use warnings;
use Mojo::DOM;
open (my $fh,"<","y.html") or die $!;
my $dom = Mojo::DOM->new(do{local $/ = undef; <$fh>});
$dom->find("*")->each( sub { $_->content( $_->content =~ s/s/&;nbsp;/gr ) } );
print $dom;
上面脚本的结果 <p class="MsoNormal" style="margin-top:1.0pt;margin-right:0cm;margin-bottom:1.0pt; margin-left:34.0pt;text-indent:-19.8pt"><span lang="nl-be" style="font-size:10.0pt; font-family:symbol;color:black;mso-ansi-language:nl-be">·<span class="grame"><span style="font-s ize:7.0pt;color:black"> <span style="font-size:10.0pt;font-family:arial;color:black">Kit<span style="font-size:10.0pt;font-family:arial;color:black"> <span class="spelle"><i><span&nb sp;style="font-size:10.0pt;font-family:arial">Strongyloides<i><span style="font-size:10.0pt;font-family:arial"> <span class="spelle">ratti<span style="font-size:10.0pt;font-family:arial"> (n r. 9450) van <span class="spelle">Bordier Affinity Products. <span lang="nl-be" style="font-size:10.0pt;font-family: arial;mso-ansi-language:nl-be">Zie bijsluiter in bijlage: CLKB_B_030 6.

PS：我尝试使用Mojo :: DOM,但没有必要使用它,你可以尝试任何其他解析器,如果你想,我仍然想知道我的代码有什么问题？ 解决方法
这是一个标记输入的工作,使其更容易使用.因此,我建议使用
HTML::TokeParser
#!/usr/bin/perl
use strict;
use warnings;
use utf8;
use HTML::TokeParser;
my $data = do {local $/; <DATA>};
my $p = HTML::TokeParser->new($data);
while (my $token = $p->get_token) {
if ($token->[0] eq 'T') {
my $text = $token->[1];
$text =~ s/ / /g;
print $text;
} else {
print "$token->[-1]";
}
}
