Extract parameter data from XML

I have some XML to parse which contains things like this
  
<ns0:DisplacementMeasure unitCode="cubic centimeter">976</ns0:DisplacementMeasure>

Now, I can easily access the '976' value for the displacement measure using getText(), but I also need to store the 'cubit centimeter' as the displaement measure unit.

Can anyone advise how to extract this please?

Hi Baz,
  
system.debug('start...');
String xmlstring= '<root xmlns:ns0="http://tempuri.org"><ns0:DisplacementMeasure unitCode="cubic centimeter">976</ns0:DisplacementMeasure></root>';
DOM.Document xmlDOC = new DOM.Document();
xmlDOC.load(xmlstring);
String namespace = 'http://tempuri.org';
DOM.XMLNode rootElement = xmlDOC.getRootElement();
system.debug('root:' + rootElement);
dom.XmlNode DisplacementMeasure = rootElement.getChildElement('DisplacementMeasure', namespace);
system.debug('DisplacementMeasure unitCode:' + DisplacementMeasure.getAttribute('unitCode',null));
system.debug('DisplacementMeasure text:' + DisplacementMeasure.getText());
system.debug('end...');

I don't know where is your XML element so you can need a Xpath expression.

Thanks Alan.. I had alreay solved it in exactly the same way!

Ok, at least, the solution could help other people because there is always this complication with the namespace at first.
Best regards
