我尝试转换从网站接收的XML字符串：
<rosters>
<roster id_provider="928" id_course="427213" provider_course_code=" " id_roster="0" id_publishing="0" TimeStamp="3/4/2015 9:51:02 PM" provider_publishing_key="8257QP01 ">
<attendees>
<attendee id_roster_attendee="" ErrorCode="44" message="Invalid entry for id_license." TimeStamp="3/4/2015 9:51:02 PM" licensee_profession="RN" licensee_number="NONE" licensee_name=" " />
</attendees>
</roster>
</rosters>
我只得到以下内容（加上上面提到的字符串的XML转储）：
数组内容如下SimpleXMLEElement Object（[0]=>）Array（1）｛[0]=>string（413）"｝数组内容结束！
请帮忙！！！

使用下面的代码数组，我在其他地方找到了。
echo "this is my xml returned from webservice <p>" . $xmlresponse . "</p>";
$xml_string = simplexml_load_string($xmlresponse);
print_r ("this is my xml after going through simplexml_load_string" . $xml_string);
echo "<p>finally, I go through json encode and decode. </p>";
$json = json_encode($xml_string);
$array = json_decode($json,TRUE);
echo "<p>Final array contents are as follows</p>";
print_r($array);
echo "<p>Array contents ended!</p>";
这是查看代码输出的链接

<?php
$xml = '<rosters><roster id_provider="928" id_course="427213" provider_course_code=" " id_roster="0" id_publishing="0" TimeStamp="3/4/2015 9:51:02 PM" provider_publishing_key="8257QP01 "><attendees><attendee id_roster_attendee="" ErrorCode="44" message="Invalid entry for id_license." TimeStamp="3/4/2015 9:51:02 PM" licensee_profession="RN" licensee_number="NONE" licensee_name=" " /></attendees></roster></rosters>';
$array = new SimpleXMLElement($xml);
print_r($array);
?>
输出：
SimpleXMLElement Object

[roster] => SimpleXMLElement Object

或者你可以试试这个代码：
<?php
$xmlstring = '<rosters><roster id_provider="928" id_course="427213" provider_course_code=" " id_roster="0" id_publishing="0" TimeStamp="3/4/2015 9:51:02 PM" provider_publishing_key="8257QP01 "><attendees><attendee id_roster_attendee="" ErrorCode="44" message="Invalid entry for id_license." TimeStamp="3/4/2015 9:51:02 PM" licensee_profession="RN" licensee_number="NONE" licensee_name=" " /></attendees></roster></rosters>';
$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
print_r($array);
?>
输出：
Array
(
[roster] => Array
(
[@attributes] => Array
(
[id_provider] => 928
[id_course] => 427213
[provider_course_code] =>
[id_roster] => 0
[id_publishing] => 0
[TimeStamp] => 3/4/2015 9:51:02 PM
[provider_publishing_key] => 8257QP01
)
[attendees] => Array
(
[attendee] => Array
(
[@attributes] => Array
(
[id_roster_attendee] =>
[ErrorCode] => 44
[message] => Invalid entry for id_license.
[TimeStamp] => 3/4/2015 9:51:02 PM
[licensee_profession] => RN
[licensee_number] => NONE
[licensee_name] =>
)
)
)
)
)
