     * Searches $content for tags and returns information about each found tag.
     *
     * Created to support button replacing process, e.g. wrapping submit/reset
     * inputs and buttons with artisteer style.
     *
     * When all the $name tags are found, they are processed by the $filter specified.
     * Filter is applied to the attributes. When an attribute contains several values
     * (e.g. class attribute), only tags that contain all the values from filter
     * will be selected. E.g. filtering by the button class will select elements
     * with class="button" and class="button validate".
     *
     * Parsing does not support nested tags. Looking for span tags in
     * <span>1<span>2</span>3</span> will return <span>1<span>2</span> and
     * <span>2</span>.
     *
     * Examples:
     *  Select all tags with class='readon':
     *   funcFindTags($html, array('*' => array('class' => 'readon')))
     *  Select inputs with type='submit' and class='button':
     *   funcFindTags($html, array('input' => array('type' => 'submit', 'class' => 'button')))
     *  Select inputs with type='submit' and class='button validate':
     *   funcFindTags($html, array('input' => array('type' => 'submit', 'class' => array('button', 'validate'))))
     *  Select inputs with class != 'bd-button'
     *   funcFindTags($html, array('input' => array('class' => '!bd-button')))
     *  Select inputs with non-empty class
     *   funcFindTags($html, array('input' => array('class' => '!')))
     *  Select inputs with class != 'bd-button' and non-empty class:
     *   funcFindTags($html, array('input' => array('class' => array('!bd-button', '!'))))
     *  Select inputs with class = button but != 'bd-button'
     *   funcFindTags($html, array('input' => array('class' => array('button', '!bd-button'))))
     *
     * @return array of text fragments and tag information: position, length,
     *         name, attributes, raw_open_tag, body.
