RE: transform an attribute to an element

That would be the way. Although I am not sure if one of the prototypes
supports data($x/@a) instead (I think there is an issue on this).

 

Best regards

Michael

could 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> {$x/@a/data <mailto:%7b$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... :-)

Subject: transform an attribute to an element

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!
