How to skip invalid characters in XML file using PHP

php, utf-8, xml

Solution

Do you have control over the XML? If so, ensure the data is enclosed in `<![CDATA[` .. `]]>` blocks.

And you also need to clear the invalid characters:

/**
 * Removes invalid XML
 *
 * @access public
 * @param string $value
 * @return string
 */
function stripInvalidXml($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;
}

Problem

I'm trying to parse an XML file using PHP, but I get an error message: parser error : Char 0x0 out of allowed range in I think it's because of the content of the XML, I think there is a speical symbol "☆", any ideas what I can do to fix it? I also get: parser error : Premature end of data in tag item line What might be causing that error? I'm using `simplexml_load_file`. Update: I try to find the error line and paste its content as single xml file and it can work!! so I still cannot figure out what makes xml file parse fails. PS it's a huge xml file over 100M, will it makes parse error?
