I am just getting started with Simple XML

Parsing this data stored as $scorexml

SimpleXMLElement Object
(
[@attributes] => Array
    (
        [query-date-time] => 20141009T175358-0400

    (
        [sports-metadata] => SimpleXMLElement Object

                                [3] => SimpleXMLElement Object
                                    (

                                    )

                            )

                    )

            )

    )

)

and trying to get 

echo $scorexml->sports-content->sports-metadata['doc-id'];

but get an error when I try to echo it:

Parse error: syntax error, unexpected T_OBJECT_OPERATOR, expecting ',' or ';'

Any help appreciated.

  • Can you post the XML as well. – slapyo Oct 09 '14 at 22:12
  • Please actually read the ["Basic SimpleXML usage" section in the PHP Manual](http://php.net/manual/en/simplexml.examples-basic.php). And most of SimpleXML questions have been answered already, please use the search before asking. – hakre Oct 10 '14 at 13:45

Because the elements are hyphenated you need to wrap them with {''}. Attributes are fine since they are accessed like an array, like ['doc-id']. It's the elements that you need to wrap if they contain a hyphen.

$scorexml->{'sports-content'}->{'sports-metadata'}['doc-id']

Check out example #3: http://php.net/manual/en/simplexml.examples-basic.php
