Question

I am attempting to send html data in a question form from my php web application to mechanical turk so a user can see the entire html document from an email to work with. I have had difficulty thus far. In the thread linked below, I attempted to parse the html data using html5-lib.php, but I think I’m still missing a step in order to complete this.

Here’s the current error I’m receiving:

Catchable fatal error: Object of class DOMNodeList could not be converted to string in urlgoeshere.php on line 35

Here’s the current code I’m working with…

$thequestion = '<a href="linkgoeshere" target="_blank">click here</a>';


$thequestion = HTML5_Parser::parseFragment($thequestion);

var_dump($thequestion);
echo $thequestion;
//htmlspecialchars($thequestion);

$QuestionXML = '<QuestionForm xmlns="http://mechanicalturk.amazonaws.com/AWSMechanicalTurkDataSchemas/2005-10-01/QuestionForm.xsd">
  <Question>
    <QuestionContent>
      <Text>'.$thequestion.'</Text> //<--- Line35
    </QuestionContent>
    <AnswerSpecification>
      <FreeTextAnswer/>
    </AnswerSpecification>
  </Question>
</QuestionForm> ';

I’m not 100% sure if the parser is what I need to do in order to have this sent correctly – All I want to do is send html through this xml type document – I’m surprised it’s been this difficult thus far.

This is somewhat of a continuation of another thread –
What PHP code will help me parse html data in an xml form?

Take a look at DOMDocument for working with DOM/xml in PHP. If you want to embed HTML in your XML, use CDATA sections like this:

$QuestionXML = '<QuestionForm xmlns="http://mechanicalturk.amazonaws.com/AWSMechanicalTurkDataSchemas/2005-10-01/QuestionForm.xsd">
  <Question>
    <QuestionContent>
      <Text><![CDATA['.$thequestion.']]></Text>
    </QuestionContent>
    <AnswerSpecification>
      <FreeTextAnswer/>
    </AnswerSpecification>
  </Question>
</QuestionForm> ';
