Further to arnold's post here is some javascript that will do it for you. The pattern is slightly different it does a non-greedy match of everything after the second '/' to the third '/'<br />

<pre><code id="code-20-40953185-1">&lt;script&gt;
var pattern = /\/cms\/getfile\/(.*?)\//;

$(function() {
  $('#pattern').html(pattern);
  $('button').click(function() {
    var input = $('#url').val();
    var result = input.match(pattern);
    $('#resultbox').html(result[1]);
  });
});
&lt;/script&gt;</code></pre>

<div class="content wysiwyg-content">
Please see attached image. &nbsp;On the first line, I need to extract everything between the two / / <br />
<br />
Which means the / after getfile and the / after the guid. &nbsp;I just want to end up with the first guid <br />
<br />
Can someone help me with some RegEx to do that. &nbsp;I have been asked not to use substring.<br />
<br />
Thanks.<br />

Using RegEx to get a string

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Scripting Languages

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.

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.
