Je veux bien lire ton anglais, mais accepte de recevoir les réponses en
français.

« alphanumeric » = [a-zA-Z0-9]

Je suppose que ce n'est pas ce que tu veux car le code HTML ne serait
même pas bien formé.

Ah, en fait ce que tu veux c'est :
[<a href="][Any text *but* <a/>][a href="]

Sauf que le <a/> est sûrement une erreur.

Donc :
[<a href="][Any text *but* </a>][a href="]

1) Ne pas confondre </a> avec <a/>
2) ^ en dehors des [] signifie « début de ligne » et pas « exclure »
3) [<a/>] prend un seul caractère qui est soit un <, soit un a, soit
   un /, soit un >. C'est équivalent à [/<>a].

Bon, là c'est clair.

http://php.net/manual/en/regexp.reference.assertions.php

Donc :
'<a href=((?!</a>).)*<a href='

Ou plus simplement :
'<a ((?!</a>).)*<a '

> Hope I could explain well enough ...

Hope you can use Google translation or something like that.
