parser error : Start tag expected, '

问题

I am using PHP for the first time. I am using the php sample for uploading image on ebay sandbox. I am getting the following error on running the PHP file:

PHP Warning:  simplexml_load_string(): Entity: line 1: parser error : Start tag expected, '<' not found in /home/nish/stuff/market place/test/php5/UploadImage/UploadSiteHostedPictures.php on line 69
PHP Warning:  simplexml_load_string(): HTTP/1.1 200 OK in /home/nish/stuff/market place/test/php5/UploadImage/UploadSiteHostedPictures.php on line 69
PHP Warning:  simplexml_load_string(): ^ in /home/nish/stuff/market place/test/php5/UploadImage/UploadSiteHostedPictures.php on line 69

PHP Notice:  Trying to get property of non-object in /home/nish/stuff/market place/test/php5/UploadImage/UploadSiteHostedPictures.php on line 94

Relevant lines are:

69. $respXmlObj = simplexml_load_string($respXmlStr);     // create SimpleXML object from string for easier parsing
                                                      // need SimpleXML library loaded for this

92. $ack        = $respXmlObj->Ack;
93. $picNameOut = $respXmlObj->SiteHostedPictureDetails->PictureName;
94. $picURL     = $respXmlObj->SiteHostedPictureDetails->FullURL;

What I can understand is the respXMLObj is not getting set properly. I have checked that simleXML support is enabled.

Could someone please help me debug this. Thanks

回答1:

The code you refer to has this line:

//curl_setopt($connection, CURLOPT_HEADER, 1 ); // Uncomment these for debugging

it seems like you uncommented these. This will result in getting the HTTP header in your response. Which is OK for debugging, but it will create an XML parse error in simplexml_load_string.

Either comment it out again or put 0 as its value.

回答2:

In my case. I just removed the invisible character The BOM in the beginning of the XML file. How to do it - depends on your text editor.

回答3:

$hasError = false;

if ( $resp == 'Internal Server Error' || empty($resp) )
{
    $hasError = true;
}

if ( ! $hasError )
{                      
    $aux    = !empty($resp) ? explode('ï»¿', $resp) : NULL;
    $temp   = utf8_decode(trim($aux[0]));               
    $xml    = simplexml_load_string($temp); 
}

回答4:

Do a var_dump($respXmlStr); my guess is that this string is not valid XML.

As per the simplexml-load-string documentation, the first parameter is expected to be A well-formed XML string - http://php.net/manual/en/function.simplexml-load-string.php
