SOAP: looks like we got no XML document

Question

I\'m trying to create a web service but before I do I\'m trying to get a simple example that I found on the internet to work first but I keep getting the following error:

Answer 1

A byte order mark (BOM) would have the same effect as whitespace before the php tags. Here you find a PHP snippet to detect and remove a BOM. Be sure to configure you editor to not insert the BOM again.

Answer 2

Another possible solution...

I had the same problem, I was getting crazy. The solution was simple. Verifying my server.. cause it is a server error. My error was that i had put "rcp" instead of "rpc".

Answer 3

This error appears also if a soap XML response contains special Unicode characters. In my case it was REPLACEMENT CHARACTER (U+FFFD).

In details, inner function of the SoapClient xmlParseDocument sets xmlParserCtxtPtr->wellFormed property as false after parsing. It throws soap fault with looks like we got no XML document.

Answer 4

As far as I understand, the error of the SOAP parser when it comes invalid XML.

As it was with me.

1. Turn on the display of the error
2. performed in try-catch and in the catch call __getLastResponse
3. I catch another error:

Warning: simplexml_load_string(): Entity: line 1: parser error : xmlParseCharRef: invalid xmlChar value 26 in

4. The first patient was PHP5.3. Once run the script on the PHP5.4, became more informative error - I swear on an invalid character, because of which, presumably, and fell SOAP parser.

As a result, I obtained the following code:

$params = array(...);
try
{
    $response = $client->method( $params );
}
catch(SoapFault $e)
{
    $response = $client->__getLastResponse();
    $response = str_replace("&#x1A",'',$response); ///My Invalid Symbol
    $response = str_ireplace(array('SOAP-ENV:','SOAP:'),'',$response);
    $response = simplexml_load_string($response);
}

If someone will tell in the comments what a symbol, I will be grateful.

Answer 5

A bit late, but this kinda error is often caused by server-side (SOAP sense) problem :

• print/echo content
• rik's answer too
• mistake (eg I was currently having this error because of a miswritten filename in an include, generating an include error instead of executing the script...)
• bad parameter in SOAP server
• not the same compression level both sides (if compression used)

This message just inform you that the SOAP client did not receive well-formatted XML (eg. an error message instead of XML).

Try to look into your server log. If you use nginx, please look into /var/log/nginx/error.log. if "Permission denied" pop up, please change related dir owner. Hope it will work.
