How can I extract data of an external XML to PHP?

How can I extract data from XML to PHP using SimpleXML and echo?

• I've successfully integrated the LinkedIn API with my website, but I'm struggling to extract information from the XML. At the moment I'm just trying to print it out so I can proceed to use the user's information once they have logged in and given permission. Below is the format of the XML, and further down is the code I am using to extract the information. The "first name", "last name" and "headline" calls work perfectly, but where an element has sub-headings, nothing is printed out. I've tried using echo 'Positions: ' . $xml->{'positions:(title)'}; but it doesn't work. Here is the XML: <person> <id> <first-name /> <last-name /> <headline> <location> <name> <country> <code> </country> </location> <industry> <summary/> <positions total=""> <position> <id> <title> <summary> <start-date> <year> <month> </start-date> <is-current> <company> <name> </company> </position> </person> This is the code I've been using to try to extract the information. I know I have to include the sub-heading somehow but I just don't know how! echo 'First Name: ' . $xml->{'first-name'}; echo '<br/>'; echo 'Last Name: ' . $xml->{'last-name'}; echo '<br/>'; echo 'Headline: ' . $xml->{'headline'}; echo '<br/>'; echo 'Positions: ' . $xml->{'positions'}; Any help would be greatly appreciated, thanks for reading!

• Answer:

  Using SimpleXML, you'd access the LinkedIn XML data properties as follows: Anything with a dash in the property gets {}, so first-name becomes: $xml->{'first-name'} Anything without a dash such as headline, is referenced like: $xml->headline Anything that is a collection, such as positions, is referenced like: foreach($xml-positions as $position) { echo $position->title; echo $position->{'is-current'}; }
