and i am trying to parse the value of  usageThresholdValue when usageThresholdID =4001 but i am not able to do so

/methodResponse/params/param/value/struct/member[name='usageCounterUsageThresholdInformation']/value/array/data/value/struct[member/name='usageThresholdInformation']/value/array/data/value/struct[member/name='usageThresholdID']/[member/value/i4='4001']/member[name='usageThresholdValue']/value

ERROR - Failed to evaluate XPath expression: javax.xml.transform.TransformerException: A location step was expected following the '/' or '//' token.

can anyone show some lights on this , Thanks for your valuable time
