<div class="content wysiwyg-content">
I have a body of text and I want to do a conditional replace based, I am assuming with an if statement.<br />
<br />
text example: &nbsp;So I want to replace part of line 3, the attribute name, which is &nbsp;&quot;Significance&quot;, with a concatenation of line 1 value, in this case, &quot;AtPID LR score&quot; + &quot;Significance&quot;. &nbsp;How do I do this?<br />
<br />
line1 &lt;attr name= &quot;mref&quot; value = &quot;AtPID LR score&quot; index = &quot;0&quot; /&gt;<br />
line 2&lt;attr name= &quot;Method&quot; value = &quot;AtPID LR score&quot; &nbsp;index = &quot;0&quot; /&gt;<br />
line 3 &lt;attr name= &quot;Significance&quot; value = &quot;1248.12&quot; &nbsp;index = &quot;0&quot;/&gt; <br />

conditional replace using Perl

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
