Well, regex for white space vary:
Regex Tutorial - \b Word Boundaries
I used to say \< and \> for word boundary, but the PERL guys got to the POSIX and changed it after decades, so both may be \b!
So, you need to check for
- standalone \<a\>
- initial \<a[a-z]
- final [a-z]a\>
- medial [a-z]a[a-z]
but since the [a-z] check is more expensive, you might be able to check in this order, since if not \<a\> then \<a is initial and a\> is final, and medial is none of the above.

NAME
Ns_AbsoluteUrl, Ns_ParseUrl, Ns_RelativeUrl, Ns_SkipUrl - URL manipulation routines
SYNOPSIS
#include "ns.h"
int
Ns_AbsoluteUrl(Ns_DString *pds, char *url, char *baseurl)
int
Ns_ParseUrl(char *url, char **pprotocol, char **phost,
char **pport, char **ppath, char **ptail)
char *
Ns_RelativeUrl(char *url, char *location)
char *
Ns_SkipUrl(Ns_Request *request, int n)
_________________________________________________________________
DESCRIPTION
Ns_AbsoluteUrl(pds, url, baseurl)
Construct an URL based on baseurl but with as many parts of the incomplete url as possible. Return NS_OK or NS_ERROR.
Ns_ParseUrl(url, pprotocol, phost, pport, ppath, ptail)
Parse a URL into its component parts. Pointers to the protocol, host, port, path, and "tail" (last path element) will be set by ref-
erence in the passed-in pointers. The passed-in url will be modified.
Ns_RelativeUrl(url, location)
If the url passed in is for this server, then the initial part of the URL is stripped off. e.g., on a server whose location is
http://www.foo.com, Ns_RelativeUrl of "http://www.foo.com/hello" will return "/hello". Returns a pointer to the beginning of the
relative url in the passed-in url, or NULL if error. Will set errno on error.
Ns_SkipUrl(request, n)
Return a pointer n elements into the request's url.
