        Hi,

        I am trying to retrieve all the books nodes with an an interact value of 104.from the following xml.

        Am doing this within the expression shape. But getting exceptions like "Expression must evaluate to node set etc"

        Please help.

        <Parent1>
          <childBooks>
            <childBook>
             <interact>104</interact>
             <books>
               <book>
                 <author>SomeBook</author>
               </book>
               <book>
                 <author>SomeOtherBook</author>
              </book>
             </books>
            </childBook>
          <childBook>
             <interact>105</interact>
             <books>
               <book>
                 <author>SomeBook</author>
               </book>
               <book>

              i was trying this

               

              /*[local-name()='Parent1']/*[local-name()='childBooks']/*[local-name()='childBook']/*[local-name()='interact'='104']/*[local-name()='books']

                  Here is the error in your construct, onlybiz,

                   *[local-name()='interact'='104']

                  I think this may have been what you intended:

                  /*[local-name()='Parent1']/*[local-name()='childBooks']/*[local-name()='childBook']/*[local-name()='books'][../interact = '104']/*
                   

                   – wa

                      Also, I should have mentioned this one:  

                      //*[local-name()='books'][../interact = '104']/*

                      This finds all books nodes across the document that have an interact value of 104

                      -wa
