Re: transform an attribute to an element

Messagecould you give me more detail of how to use the data() function? 
is it like that:
 
for $x in document("test.xml")/test
return
          <test>
              <a> {$x/@a/data()} </a>
              {$x/b}
         </test>

I tried to execute it with quip or microsoft demo, but both failed. maybe they do not support it now.

Best regards,

  Text() is an XPath node test and thus cannot work on attributes (thanks to XPath 1.0). Use data() instead.

  but it failed when using Quip from SoftwareAG. I think the function text() can only apply to elements, not to attributes.

    Hello,



    You can do this fairly simply with a for loop and element constructors, like this:



    for $x in /test

    return

        <test>

            <a>{$x/@a/text()}</a>

            {$x/b}

        </test>



    where the text() is necessary to make sure that the value of @a gets returned

    rather than having it remain an attribute.  Basically this loop just takes

    the original document apart and then re-assemble it without the attribute but with

    the new child element.



    Hope that helps (I'm still learning this stuff also... :-)

      Hi,



      who can tell me if I can use XQuery to transform an attribute to an element?



      for example, the document is 

                  <test a="123">

                       <b>321</b>

                  </test>



      I'd like to transform the attribute "a" to an element of test.



                  <test>

                     <a>123</a>

                     <b>321</b>

                  </test>



      thank you!
