How to parse from this skill set to php?

Question

{"linkedin":"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n
<skills total=\"11\">\n  
<skill>\n    
    <id>1<\/id>\n    
    <skill>\n      
        <name>C#<\/name>\n    
    <\/skill>\n  
<\/skill>\n  
<skill>\n    
    <id>2<\/id>\n    
    <skill>\n      
        <name>C<\/name>\n    
    <\/skill>\n  
<\/skill>\n

$id =  getTextBetweenTags($user_profile['linkedin'], 'id');
      $fname = getTextBetweenTags($user_profile['linkedin'], 'first-name');
      $lname = getTextBetweenTags($user_profile['linkedin'], 'last-name');
      $pictureurl = getTextBetweenTags($user_profile['linkedin'], 'picture-url');
      $email = getTextBetweenTags($user_profile['linkedin'], 'email-address');
$headline = getTextBetweenTags($user_profile['linkedin'], 'headline'); 
$summary = getTextBetweenTags($user_profile['linkedin'], 'summary');  

    $interests=getTextBetweenTags($user_profile['linkedin'], 'interests'); 

$user_profile_skills = $OBJ_linkedin->profile('~/skills:(id,skill:(name))');  

$stringData = json_encode($user_profile_skills);
$xml = simplexml_load_string($stringData->linkedin);

How to retrive each value from it using php?. This is the JSON encoded form of skill set getting from linkedin. I am new to these kind of things. Please help me.

Answer 1

You've got an XML document inside your JSON object, so we need to do two things.

Decode the JSON:

$obj = json_decode($jsonString);

Use SimpleXML to parse the XML.

$xmlDoc = simplexml_load_string($obj->linkedin);

As long as the XML is correctly formatted you will be able to process it as your needs dictate using SimpleXML. Further information on SimpleXML can be found here: http://php.net/simplexml
