Try this pattern:  ([^a-z\b0-9]?)(MAN)([^a-z\b0-9]?).

<div>
I tried it with man but sadly it did not work.<br />
<br />
([^a-z\b0-9]?)(man)([^a-z\<wbr />b0-9]?)<br />
but unfortunately this matched man in 'germany' and other words.<br />
My code adds ( ) and (?=[^&gt;]*&lt;) to your expression to filter HTML to become <br />
(([^a-z\b0-9]?)(man)([^a-z<wbr />\b0-9]?))(<wbr />?=[^&gt;]*&lt;) <br />
Would this have broken it?

Sorry I forgot about the case sensitive when copy paste here. This is the best pattern that I can think of (and already checked): &nbsp;<b>(([^a-zA-Z]+)|(\b))(MAN)((<wbr />[^&gt;a-zA-Z]<wbr />)|(\b))<br />
</b><br />
Hope it could help.

Thanks Ozo that worked fine!

<div>
<div class="content wysiwyg-content">
So in this example, the word man is found in amongst HTML markup.<br />
(MAN)(?=[^&gt;]*&lt;)<br />
It is matched ok but it also matches for occurrences in the HTML of MANAGEMENT or GERMANY etc. &nbsp;It isn't as easy as saying I want to see a space on each side either since punctuation and non alpha numeric characters would be acceptable.<br />
How can I enhance the pattern so that alpha numeric characters preceding or following prevent matching?<br />
Thanks!

How to alter this REGEX pattern to match whole words rather than parts?

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.

Regular Expressions

An algorithm is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.
