使用html注释解析xml时出现Guzzle错误[关闭]

Question

I'm getting this error from guzzle. the xml has a html comment in it which I think is breaking it. Any experience with this specifically in relation to guzzle because it is at the point that i try to get the response at xml where this error is through e.g. $res->xml(). $res alone or $res->getBody() don't seem to help me.

"Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /home/mso/public_html/connector/vendor/guzzlehttp/guzzle/src/Message/Response.php:168 Stack trace: #0 /home/mso/public_html/connector/vendor/guzzlehttp/guzzle/src/Message/Response.php(168): SimpleXMLElement->__construct('Please use a mi...', 2048, false, '', false) #1 /home/mso/public_html/connector/get_dat.php(23): GuzzleHttp\Message\Response->xml() #2 {main} Next exception 'GuzzleHttp\Exception\XmlParseException' with message 'Unable to parse response body into XML: String could not be parsed as XML' in /home/mso/public_html/connector/vendor/guzzlehttp/guzzle/src/Message/Response.php:174 Stack trace: #0 /home/mso/public_html/connector/get_data.php(23): GuzzleHttp\Message\Response->xml() #1 {main} thrown in /home/mso/public_html/connector/vendor/guzzlehttp/guzzle/src/Message/Response.php on line 17

You can try to check your xml prior to load using:

$oXmlUtilities = new cXmlUtilities();
// Validate xml file by setting internal errors.
libxml_use_internal_errors( true );
try
{
    $sTmpString = simplexml_load_string( $sContents );
}
catch( Exception $oException )
{
    $sError = $oException->GetMessage();
}

// If xml validates and isn't empty call guzzle:
if( empty( $sError ) && ( $sTmpString ) )
{
    // XML is valid.

Otherwise you may need to parse the string through a regex for html comments:

<!--(.*?)-->
