Question

我有一个这样的文本文件：

This is a <div class="animal">fish</div>. He likes to <div class="verb">swim</div>.
This is a <div class="animal">bear</div>.
The <div class="animal">bear</div> likes <br> to eat fish.

我需要在所有文本（包括标点符号）周围放置标记，这些标记不在任何<div>标记内。 E.g：

<div class="other">This is a </div><div class="animal">fish</div><div class="other">. He likes to </div><div class="verb">swim</div><div class="other">.</div>
<div class="other">This is a </div><div class="animal">bear</div><div class="other">.</div>
<div class="other">The </div><div class="animal">bear</div><div class="other"> likes <br> to eat fish.</div>

多个嵌套<div>可能出现在同一行。
<div>从不跨越多行。

如何在文件的所有未标记文本部分周围标记<div class="other">和</div>？

Answer 1

此awk应该：

awk '!/^</ {$0="<div class=\"other\">"$0"</div>"}1'
<div class="other">This is a <div class="animal">fish</div>. He likes to <div class="verb">swim</div>.</div>
<div class="other">This is a <div class="animal">bear</div>.</div>
<div class="other">The <div class="animal">bear</div> likes <br> to eat fish.</div>

它只是围绕不以<div.. /div>

开头的每一行包裹<

Answer 2

使用Perl，您可以在split元素上<div>并同时捕获它们。结果就是这个清单

This is a
<div class="animal">fish</div>
. He likes to
<div class="verb">swim</div>
. This is a
<div class="animal">bear</div>
. The
<div class="animal">bear</div>
likes <br> to eat fish.

然后，所有必要的是将<div>括号中的那些元素中的那些元素括起来并重新加入这些元素。

这个程序演示了，虽然它产生了一些讨厌的HTML！

use strict;
use warnings;

my $text = <<'__END_TEXT__';
This is a <div class="animal">fish</div>. He likes to <div class="verb">swim</div>.
This is a <div class="animal">bear</div>.
The <div class="animal">bear</div> likes <br> to eat fish.
__END_TEXT__

my @parts = split m{(<div\b.+?</div>)}, $text;

print "- `$_`\n" for @parts;

for my $part (@parts) {
  $part = qq{<div class="other">$part</div>} unless $part =~ m{^<div\b};
}

my $fixed_text = join '', @parts;
print $fixed_text, "\n";

<强>输出

<div class="other">This is a </div><div class="animal">fish</div><div class="other">. He likes to </div><div class="verb">swim</div><div class="other">.
This is a </div><div class="animal">bear</div><div class="other">.
The </div><div class="animal">bear</div><div class="other"> likes <br> to eat fish.
</div>

Answer 3

这可能适合你（GNU sed）：

 sed '/\n/!{s/<div/\n&/g;s/\/div>/&\n/g};/^<div/!{s/^/<div class="other">/;s/\n\|$/<\/div>&/};P;D' file

这会将该行分成一系列语句。

如何在<div>标签内的所有内容周围放置标签？</div>
