如何使用PHP跳过XML文件中的无效字符

您可以控制XML吗？如果是这样，请确保将数据括在

<![CDATA[

]]>

并且您还需要清除无效字符：

function stripInvalidXml($value){    $ret = "";    $current;    if (empty($value))     {        return $ret;    }    $length = strlen($value);    for ($i=0; $i < $length; $i++)    {        $current = ord($value{$i});        if (($current == 0x9) || ($current == 0xA) || ($current == 0xD) || (($current >= 0x20) && ($current <= 0xD7FF)) || (($current >= 0xE000) && ($current <= 0xFFFD)) || (($current >= 0x10000) && ($current <= 0x10FFFF)))        { $ret .= chr($current);        }        else        { $ret .= " ";        }    }    return $ret;}
