I assumed from the example strings given that the positions of the characters within the strings was important. That is, "ABCXXXXXX" would be a good match, but "XABCXXXXX" would not.
If position is not important then my solution doesn't work at all. If my assumption was correct however, then using Algorithm::Diff::LCSidx to compare the pattern against the target string will work, but requires the additional step of checking to see if the contents of the two arrays of indices pointed to by the returned references are equivalent. Unless I missed something when skimming through the documentation that is.
Thanks, tye. Hanging out around here I definitely learn something new (usually several somethings) every day.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
