<td class='htmllist_td_nbr' >8</td> 
<td class='htmllist_td' >NehaA5.12</td> 
</tr>

    想<tr>和</tr>标签之间找到NehaA然后更改匹配模式和HTML标签替换

    `<tr class='htmllist_tr'>`

    或

    <tr class='htmllist_tr' style="background-color:yellow">

    到

    `<tr class='htmllist_tr' style="background-color:red">` *

    试过这种

    sed -e "/NehaA/ s/\'<tr class='htmllist_tr'>\'/\'<tr class='htmllist_tr' style="background-color:red">\'/ ;" 2932_TABLE2.txt

    没有工作，请帮助

    在AWK做它/ sed的是不是最好的主意。你为什么不使用Python +美丽的汤？在perl中，你可以使用（我认为，我没有使用它）HTML :: Parser。 –

    HTML与XML一样是结构化数据。您不能将其视为普通的文本文件。有[可用的许多模块]（http://search.cpan.org/search?m=module&q=html）将解析您的HTML并允许您修改它。 – Borodin

    如果你不使用HTML解析器那就试试这个获得一个可用的答案：

    $ awk -v RS='</tr>\\s*' '/Neha/{ORS=RT; sub(/<tr[^>]+>/,""); print "<tr class=\047htmllist_tr\047 style=\"background-color:red\">" $0}' file 
<tr class='htmllist_tr' style="background-color:red"><td class='htmllist_td' >INDX01</td> 
<td class='htmllist_td_nbr' >964.87</td> 
<td class='htmllist_td_nbr' >95.13</td> 
<td class='htmllist_td' >NehaA9.86</td> 
</tr> 
<tr class='htmllist_tr' style="background-color:red"><td class='htmllist_td' >UNDOTBS1</td> 
<td class='htmllist_td_nbr' >156.25</td> 
<td class='htmllist_td_nbr' >8</td> 
<td class='htmllist_td' >NehaA5.12</td> 
</tr>

    它使用GNU AWK多焦RS和RT。

    这是我使用HTML::TreeBuilder的方式。代码本身是自我解放的。我建议你阅读文档，因为不建议分析HTML using regex。

    #!/usr/bin/perl 
use strict; 
use warnings; 
use HTML::TreeBuilder; 

my $str = <<'HTML' 
<html> 
<head> 
</head> 
<body> 
<table> 
<tr class='htmllist_tr' style="background-color:yellow" > 
<td class='htmllist_td' >INDX01</td> 
<td class='htmllist_td_nbr' >964.87</td> 
<td class='htmllist_td_nbr' >95.13</td> 
<td class='htmllist_td' >NehaA9.86</td> 
</tr> 
<tr class='htmllist_tr' > 
<td class='htmllist_td' >UNDOTBS1</td> 
<td class='htmllist_td_nbr' >156.25</td> 
<td class='htmllist_td_nbr' >8</td> 
<td class='htmllist_td' >NehaA5.12</td> 
</tr> 
</table> 
</body> 
</html> 
HTML 
; 


my $root = HTML::TreeBuilder->new_from_content($str); 

my @tr = $root -> find_by_tag_name('tr'); 

foreach (@tr) { 
    if ($_ -> find_by_attribute("class","htmllist_tr")) { 
     my @tds = $_ -> look_down(_tag => 'td', class => 'htmllist_td'); 
     my @children = map {$_ -> content_list} @tds; 
     if(grep(/NehaA/, @children)) { 
      $_ -> attr('style', 'background-color:red'); 
     } 
    } 
} 

print $root -> as_HTML(undef, " ");

    @ED ..sorry的cofusion ..this是原始文件

    <table class='htmllist'> 
<tr class='htmllist_tr' ><th class='htmllist_th' >TABLESPACE<br>NAME</th> 
<th class='htmllist_th' >ALLOCATED<br>SPACE<br>GB</th> 
<th class='htmllist_th' >CURRENT<br>FREE<br>SPACE<br>GB</th> 
<th class='htmllist_th' >CURRENT<br>FREE<br>SPACE<br>PCT</th> 
<tr class='htmllist_tr' style="background-color:yellow" ><td class='htmllist_td' >INDX01</td> 
<td class='htmllist_td_nbr' >964.87</td> 
<td class='htmllist_td_nbr' >95.78</td> 
<td class='htmllist_td' >NehaA9.93</td> 
</tr> 
<tr class='htmllist_tr' ><td class='htmllist_td' >TEMP</td> 
<td class='htmllist_td_nbr' >125</td> 
<td class='htmllist_td_nbr' >124.63</td>

<td class='htmllist_td_nbr' >22.85</td> 
<td class='htmllist_td' >NehaA14.62</td> 
</tr> 
</table>

    我要像

    <table class='htmllist'> 
<tr class='htmllist_tr' ><th class='htmllist_th' >TABLESPACE<br>NAME</th> 
<th class='htmllist_th' >ALLOCATED<br>SPACE<br>GB</th> 
<th class='htmllist_th' >CURRENT<br>FREE<br>SPACE<br>GB</th> 
<th class='htmllist_th' >CURRENT<br>FREE<br>SPACE<br>PCT</th> 
<tr class='htmllist_tr' style="background-color:red" ><td class='htmllist_td' >INDX01</td> 
<td class='htmllist_td_nbr' >964.87</td> 
<td class='htmllist_td_nbr' >95.78</td> 
<td class='htmllist_td' >NehaA9.93</td> 
</tr> 
<tr class='htmllist_tr' ><td class='htmllist_td' >TEMP</td> 
<td class='htmllist_td_nbr' >125</td> 
<td class='htmllist_td_nbr' >124.63</td> 
<td class='htmllist_td_nbr' >99.7</td> 
</tr> 
<tr class='htmllist_tr' ><td class='htmllist_td' >TEMP_EDDDATA</td> 
<td class='htmllist_td_nbr' >205.99</td> 
<td class='htmllist_td_nbr' >198.52</td> 
<td class='htmllist_td_nbr' >96.37</td> 
</tr> 
<tr class='htmllist_tr' style="background-color:red"><td class='htmllist_td' >UNDOTBS1</td> 
<td class='htmllist_td_nbr' >156.25</td> 
<td class='htmllist_td_nbr' >22.85</td> 
<td class='htmllist_td' >NehaA14.62</td> 
</tr> 
</table>
    然而

    输出，当我使用这个

    awk -v RS='</tr>\\s*' '/Neha/{ORS=RT; sub(/<tr[^>]+>/,""); print "<tr class=\047htmllist_tr\047 style=\"background-color:red\">" $0}' text.txt

    这是给我这样的输出

    <tr class='htmllist_tr' style="background-color:red"><table class='htmllist'> 
<th class='htmllist_th' >TABLESPACE<br>NAME</th> 
<th class='htmllist_th' >ALLOCATED<br>SPACE<br>GB</th> 
<th class='htmllist_th' >CURRENT<br>FREE<br>SPACE<br>GB</th> 
<th class='htmllist_th' >CURRENT<br>FREE<br>SPACE<br>PCT</th> 
<tr class='htmllist_tr' style="background-color:yellow" ><td class='htmllist_td' >INDX01</td> 
<td class='htmllist_td_nbr' >964.87</td> 
<td class='htmllist_td_nbr' >95.78</td> 
<td class='htmllist_td' >NehaA9.93</td> 
</tr><tr class='htmllist_tr' style="background-color:red"> 
<td class='htmllist_td' >UNDOTBS1</td> 
<td class='htmllist_td_nbr' >156.25</td> 
<td class='htmllist_td_nbr' >22.85</td> 
<td class='htmllist_td' >NehaA14.62</td> 
</tr>

    让我知道如果这有意义

    请将这些细节添加到你的问题而不是答案。其次，你可以尝试'HTML :: TreeBuilder'。它会给你，你的期望*输出*。用* regex *解析html不是一个好习惯;它会在某个地方破裂。请告诉我，如果您有任何疑问。 –
