Une espace a été supprimée dans ta réponse, j'avais écrit :
 '<a ((?!</a>).)*<a '
et non :
 '<a ((?!</a>).)*<a'

Quel que soit le contexte, un '<a ' (ne pas oublier l'espace) doit
toujours être suivi d'un '</a>', même si c'est un '<a name=' et pas
un '<a href='.

Mais on peut améliorer ce test en prévoyant aussi la fin de fichier :
'<a ((?!</a>).)*(<a |$)'

Si vraiment tu tiens à la version longue :
'<a href=((?!</a>).)*(<a href=|$)'

C'était avec plaisir.
