Like this:

Or do you want to let the spaces as-is?

<div class="content wysiwyg-content">
Hello,<br />
<br />
I tried to modify one ascii file with my inputs but i have to modify some lines with specific structures like below;<br />
<br />
Structure is like below:<br />
subvar.str ( &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; #SEARCH_TERM# &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;) = '#VALUE#' ! Some Text<br />
<br />
- There is no rule for white spaces around search term there can be found or not.<br />
<br />
<br />
This is the real example:<br />
<br />
subvar.str ( &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $_partname &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;) = '&quot;XX-2000-1050&quot;' ! $_partname, Definition<br />
<br />
<br />
I'd like to find &quot;$_partname&quot; and then change it's value &quot;XX-2000-1050&quot;. If it's fully string i have to put queto sign on my string otherwise if it's double or integer i'll not put anything begin and end of my value.<br />
<br />
I'll appreciate if you can help about this.

How to apply regex in my case in C#

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.

Regular Expressions

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
