Поиск X с заменой на A

[lbarmen]

Всем привет, помогите с такой проблемой:
получаю текст, где есть много ссылок
....href="x1".....href="x2"........ ..и т.д.
мне нужно получить X, обработать, а затем обратно вставить в X

Читай про preg_match.

Вроде как нашел, но способ как то не особо радует) и еще он не видит ссылку без кавычек

<?php
/**
 * Replaces anchor tags with text
 * - Will search string and replace all anchor tags with text (case insensitive)
 *
 * How it works:
 * - Searches string for an anchor tag, checks to make sure it matches the criteria
 *         Anchor search criteria:
 *             - 1 - <a (must have the start of the anchor tag )
 *             - 2 - Can have any number of spaces or other attributes before and after the href attribute
 *             - 3 - Must close the anchor tag
 *
 * - Once the check has passed it will then replace the anchor tag with the string replacement
 * - The string replacement can be customized
 *
 * Know issue:
 * - This will not work for anchors that do not use a ' or " to contain the attributes.
 *         (i.e.- <a href=http: //php.net>PHP.net</a> will not be replaced)
