Does this work for you?<br />

<pre><code id="code-20-42661614-1">.*&quot;(\d)&quot;</code></pre>
Group1 matches with 3.<br />
<br />
Or just this?<br />

<pre><code id="code-20-42661614-2">&quot;(\d)&quot;</code></pre>

.*"(\d)"

Group1 matches with 3.

Or just this?


"(\d)"

<div>
It seems to work.<br />
<br />
since the &quot;3&quot; field could be any number, I found that &quot;(\d+)&quot; seems to work.<br />
I know <b>\d</b> matches &quot;any digit&quot;...<br />
but, could you explain a little of why this simple regex &nbsp;works?<br />
<br />
Thanks much

Need to capture the "3" value using REGEX in the following  string:

How to capture a particular delimited  field using REGEX

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.
