parser error : Start tag expected, '<' not found
提问by nish
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:
我是第一次使用 PHP。我正在使用 php 示例在 ebay 沙箱上上传图像。运行PHP文件时出现以下错误：
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 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:
相关线路是：
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.
我能理解的是 respXMLObj 没有正确设置。我已检查是否启用了 simleXML 支持。
Could someone please help me debug this. Thanks
有人可以帮我调试这个。谢谢

The code you refer to has this line:
您引用的代码有这一行：
//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.
好像你取消了这些注释。这将导致在您的响应中获取 HTTP 标头。这对于调试来说是可以的，但它会在simplexml_load_string.
Either comment it out again or put 0as its value.
再次将0其注释掉或将其作为其值。

In my case. I just removed the invisible character The BOMin the beginning of the XML file. How to do it - depends on your text editor.
就我而言。我刚刚删除了 XML 文件开头的不可见字符 BOM。怎么做 - 取决于你的文本编辑器。

$hasError = false;
if ( $resp == 'Internal Server Error' || empty($resp) )
{
$hasError = true;
}
if ( ! $hasError )
{
$aux = !empty($resp) ? explode('???', $resp) : NULL;
$temp = utf8_decode(trim($aux[0]));
$xml = simplexml_load_string($temp);
}

Do a var_dump($respXmlStr);my guess is that this string is not valid XML.
做一个var_dump($respXmlStr);我的猜测是这个字符串不是有效的 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
根据 simplexml-load-string 文档，第一个参数应该是A well-formed XML string- http://php.net/manual/en/function.simplexml-load-string.php
