使用Perl編輯HTML文件

Question

以下輸出由第三方工具生成，該工具根據XML模式驗證XML文件。它會輸出驗證錯誤。好的，這只是一個小小的背景。

從上面的錯誤顯示在HTML中，我希望能夠使用Perl執行「語法突出顯示」。例如，我希望能夠突出上述文本的某些部分。

具體而言，我想將符合「Line [0-9] *」的任何文本着色爲粗體和紅色。我試圖嘗試正則表達式搜索和替換，但我沒有那麼成功。

任何指針/提示將是太棒了。

謝謝！

Line 8: Element 'alphabet', attribute 'letters': The value 'XYZ' does not match the fixed value constraint 'ABC'. 
Line 185: Element 'drink': The attribute 'coffee' is required but missing. 
Line 254: Element 'timeout': This element is not expected. 
Line 269: Element 'commands': This element is not expected. Expected is one of (eat, drink, sleep). 
Line 812: Element 'software': The attribute 'version' is required but missing. 
Line 876: Element 'windows-software': The attribute 'version' is required but missing. 
Line 890: Element 'contact': The attribute 'telephone' is required but missing. 
Line 890: Element 'operating': The attribute 'mode' is required but missing.

有這樣的嘗試：

#!/usr/bin/perl 
use strict; 
use warnings; 

while(<DATA>) { 
    s#(Line \d+)#<span style="font-weight:bold;color:red;">$1</span>#; 
    s#(Element\s|attribute\s)('[^']*')#$1<span style="font-weight:bold;color:blue;">$2</span>#g; 
    print 
} 

__DATA__ 
Line 8: Element 'alphabet', attribute 'letters': The value 'XYZ' does not match the fixed value constraint 'ABC'. 
Line 185: Element 'drink': The attribute 'coffee' is required but missing. 
Line 254: Element 'timeout': This element is not expected. 

輸出

<span style="font-weight:bold;color:red;">Line 8</span>: Element <span style="font-weight:bold;color:blue;">'alphabet'</span>, attribute <span style="font-weight:bold;color:blue;">'letters'</span>: The value 'XYZ' does not match the fixed value constraint 'ABC'. 
<span style="font-weight:bold;color:red;">Line 185</span>: Element <span style="font-weight:bold;color:blue;">'drink'</span>: The attribute <span style="font-weight:bold;color:blue;">'coffee'</span> is required but missing. 
<span style="font-weight:bold;color:red;">Line 254</span>: Element <span style="font-weight:bold;color:blue;">'timeout'</span>: This element is not expected. 

相反的風格attribut的，你可以使用一個CSS類。

s#(Line \d+)#<span class="bold_red">$1</span>#;
