API文档不显示他们,但file_get_html和str_get_html功能有一堆额外的乐趣参数,只需打开simple_html_dom.php:

function file_get_html(
  $url, $use_include_path = false, $context=null, $offset = -1,
  $maxLen=-1,
  $lowercase = true,
  $forceTagsClosed=true,
  $target_charset = DEFAULT_TARGET_CHARSET,
  $stripRN=true,
  $defaultBRText=DEFAULT_BR_TEXT)

function str_get_html(
  $str,
  $lowercase=true,
  $forceTagsClosed=true,
  $target_charset = DEFAULT_TARGET_CHARSET,
  $stripRN=true,
  $defaultBRText=DEFAULT_BR_TEXT)

也许你可以设置$stripRN为false,否则会这样做simple_html_dom->prepare():

//before we save the string as the doc...  strip out the \r \n's if we are told to.
if ($stripRN) {
    $str = str_replace("\r", " ", $str);
    $str = str_replace("\n", " ", $str);
}
