Hi!
I am trying to parse an xml with simplexml;

This is the XML file:
<ExecuteResponse version="0.4.0" xsi:schemaLocation="http://www.opengeospatial.net/wps http://www.bnhelp.cz/schema/wps/0.4.0/wpsExecute.xsd">
<ows:Identifier>
		visibility2
	</ows:Identifier>
&#8722;
	<Status>
<ProcessSucceeded/>
</Status>
&#8722;
	<ProcessOutputs>
&#8722;
	<Output>
<ows:Identifier>
				output
			</ows:Identifier>
<ows:Title>
				Resulting output map
			</ows:Title>
<!--Element Abstract not set-->
<ComplexValueReference encoding="utf-8" format="image/png" ows:reference="http://localhost/wps/wpsoutputs/output-2006-10-26-17-53-42.tif" schema=""/>
</Output>
</ProcessOutputs>
</ExecuteResponse

This is the dump of the xml obj:

object(SimpleXMLElement)#1 (3) {
  ["@attributes"]=>
  array(1) {
    ["version"]=>
    string(5) "0.4.0"
  }
  ["Status"]=>
  object(SimpleXMLElement)#3 (1) {
    ["ProcessSucceeded"]=>
    object(SimpleXMLElement)#2 (0) {
    }
  }
  ["ProcessOutputs"]=>
  object(SimpleXMLElement)#4 (1) {
    ["Output"]=>
    object(SimpleXMLElement)#5 (2) {
      ["comment"]=>
      object(SimpleXMLElement)#6 (0) {
      }
      ["ComplexValueReference"]=>
      object(SimpleXMLElement)#7 (1) {
        ["@attributes"]=>
        array(3) {
          ["encoding"]=>
          string(5) "utf-8"
          ["format"]=>
          string(9) "image/png"
          ["schema"]=>
          string(0) ""
        }
      }
    }
  }
}

As you can see, ows:reference attribute, is skipped.

Thx
