XML : Parsing XML with php to Array

I've tried to parse a XML String with php.

The example of XML is

  <?xml version="1.0"?>  <root>      <Log>          <Item>              <name>![CDATA[James]]</name>              <address>![CDATA[Korea]]</address>              <email>![CDATA[Korea@gmail.com]]</email>          </Item>          <Item>              <name>![CDATA[James2]]</name>              <address>![CDATA[Korea2]]</address>              <email>![CDATA[Korea@gmail.com2]]</email>          </Item>      </Log>  </root>    

My Parsing PHP Code is

  $xml = simplexml_load_string($input,null,LIBXML_NOCDATA);  $xml=json_decode( json_encode( $xml),true);    

However, When I try to get sizeof($xml['Log']['Item']), have some problems.

If XML have One 'Item' , then sizeof($xml['Log']['Item']) return '3' .

but If XML have 4 'Item's , then it return '4'.

I want to return 1, if XML have One 'Item'.

How can I solve this problem.?
