I am trying to get a list of all jpg files in a html file. The html file is complex, and not formatted clearly. (at least not to a human) I have tried to add blank lines around the image tags, but that is not helping to split up the results enough. I imagine there has to be an easy way to get a list of files?<br />

&lt;img src=&quot;directory/test.jpg&quot; alt=&quot;&quot; width=&quot;200&quot; height=&quot;250&quot;&gt;<br />

becomes:<br />
directory/test.jpg

Extract list of jpg files

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.

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.
