How to ignore namespace when selecting XML nodes with XPath

Question

I have to parse an XML document that looks like this:

Answer 1

Use:

/*/*/*/*/*
        [local-name()='REPORT_DATA' 
       or 
         local-name()='REPORT_HEADER'
        ]

Anyone care for more complete syntax?

String xPathExpression = "/*[local-name()='OASISReport]
                          /*[local-name()='MessagePayload]
                          /*[local-name()='RTO]
                          /*[local-name()='REPORT_ITEM]
                          /*[local-name()='REPORT_DATA"];

Btw, if the XPath also requires the element index position:

String xPathExpression = "/*[local-name()='OASISReport][1]
