Yeah, I did not pay attention. My regex checks if there is a lower case character in group 3.

Yeah, I did not pay attention. My regex checks if there is a lower case character in group 3.

<div>
<div class="content wysiwyg-content">
I have the following string:<br />
<br />
op=func&amp;test1=abcd&amp;test2=t<wbr />est<br />
<br />
Using a regex in an apache rewritecond I'm wanting to extract the value assigned to test1<br />
<br />

<pre><code id="code-10-28712677-1">^(.+)&amp;test1=([^&amp;]+)(.*)$</code></pre>
<br />
this results in 3 capture groups:<br />
<br />
1) op=func<br />
2) abcd<br />
3) &amp;test2=test<br />
<br />
which is great, I can use all these elements in my apaache rewriterule<br />
<br />
However, I'm only interested in finding a match where capture group 2 (in this case, &quot;abcd&quot;) contains a lowercase character. &nbsp;This string can be any length. &nbsp;If the value was &quot;ABCD&quot; I dont want to find a match.<br />
<br />
How can this be done

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.
