Распишу поподробней. Необходимо найти поле с именем pseudo_*********, где ******* разное. Но таких полей создается несколько (иногда 5, иногда 25).
Стал разбираться и выяснил, в чем отличие
Это то что нам нужно
<input id="" name="pseudo_7ab98a93b5" value="" maxlength="20" tabindex="101" style="background: url(/images/icon_member.png) left center no-repeat; padding-left: 18px;position: relative;" class="window_membres_inscription_pseudo" autocomplete="off" type="text">
Выделил отличия - присутствие id="" и position: relative;
А это остальные (еще можно отметить присутствие либо visibility: hidden; либо position: absolute; либо display: none;)

Составил регулярку
<input\ id="".*relative;"\ class="window_membres_inscription_pseudo"\ autocomplete="off"\ type="text">
а можно добавить еще самое короткое (потому как ) id="" пустое, и будет вот так
<input\ id="".*?position:\ relative;"\ class="window_membres_inscription_pseudo"\ autocomplete="off"\ type="text">
В шаблоне находит только 1 елемент. Вроде задача решена.. Но при проверке елемент не находит..
