[xquery-talk] changing structure based on input value

[Dmitri.Colebatch at toyota.com.au]

Mark,

Thats exactly what I was looking for, thanks... apologies for the simple
question (o:

btw - I had to make two changes, the "else if" needed a "then" and the
whole thing needed an "else":

for $input in $this
return
   if ($input/foobar/abc/text() = 4) then
      <myoutput>
          <value>{ $input/foobar/xyz/text() }</value>
      </myoutput>
   else if ($input/foobar/abc/text() = 5) then
      <somethingelse>
          <value>{ $input/foobar/xyz/text() }</value>
      </somethingelse>
   else
      <rubbish>{ $input/foobar/abc/text() }</rubbish>

but it does what is required.

thanks again.

cheers
dim

You can do something like this:


for $indoc in doc("inputDocument.xml")
return
   if (data($indoc/abc) = 4) then
      <myoutput>
          <value>{ $indoc/xyz/text() }</value>
      </myoutput>
   else if (data($indoc/abc) = 5)
      <somethingelse>
          <value>{ $indoc/xyz/text() }</value>
      </somethingelse>
