PHP Generated Xml Shows Invalid Char Value 27 Message

PHP generated XML shows invalid Char value 27 message

A useful function to get rid of that error is suggested on this website.
http://www.phpwact.org/php/i18n/charsets#common_problem_areas_with_utf-8

When you put utf-8 encoded strings in a XML document you should remember that not all utf-8 valid chars are accepted in a XML document http://www.w3.org/TR/REC-xml/#charsets

So you should strip away the unwanted chars, else you’ll have an XML fatal parsing error such as above

function utf8_for_xml($string)
{
    return preg_replace ('/[^\x{0009}\x{000a}\x{000d}\x{0020}-\x{D7FF}\x{E000}-\x{FFFD}]+/u', ' ', $string);
}

Hope that saves someone else some time..

XML Error: Invalid character

Make sure the web server you're pulling the file from is sending the correct character encoding when it serves the page. You should see something like this in the response headers:

Content-Type:"text/xml; charset=utf-8"

The headers can be viewed in the network panel of the inspector in any modern browser, when you request the XML file directly.

You should also specify the encoding in the file itself. The first line should look something like this:

<?xml encoding='UTF-8'?>

If these fail, you can always try using utf8_decode() which is an XML_Parser function that will attempt to convert the data to iso-8859-1.

Failed loading XML:xmlParseCharRef: invalid xmlChar value

XML has no notion of HTML entities. As a hack, you can decode the entities first with

$html = html_entity_decode($file_contents, ENT_QUOTES, "utf-8");

and then try parse $html with the XML parser. Just hope it's tolerant enough, because HTML is still not valid XML.

The good news is that you can then remove the if (strstr("&", hack because that is taken care of by html_entity_decode().
