我现在的代码 找不到 /n 字符

请问如何找到嗯?

扔上来的代码

$xml = simplexml_load_file("ZH-CNstrings.xml"); // echo $xml->getName() . "
"; $cou = 1; foreach($xml->children() as $child) { echo $child->getName(); if($child->getName() == "string-array"){ foreach ($child as $key2 => $value2) { echo "
"; } }else{ if (strstr($child,"color") or strstr($child,"%1") or strstr($child,"%s") or strstr($child,"\n") ) { echo "有 特殊字符 "; $cou++; } echo "
"; } }
