Hey Sony,
I found another small typo in your query - the keyword 'node' is missing in your replace statement. So if you execute the query below you should be fine.
for $childentry in $c//childentry return replace value of *node* $childentry/@id with concat('New Child: ', data($c//childentry/@id))
I'm sure the somewhat unrelated syntax error message didn't help you to find this ... sorry for that.
Regards, Lukas

.. I* see the syntax error : * *[XPST0003] Expecting ")", found "v".*
when I try :
for $childentry in $c//childentry return replace value of $childentry/@id with concat('New Child: ', data($c//childentry/@id))
To modify the child entries like so:
<childentry id="1"> ----- > <childentry id="New Child: 1">

... Replacing the values of attribute nodes doesn't seem to work as expected when I use modify. Please see my previous post with correction in the typo.

Please ignore the typo. My sample xquery looks something like this:
for $childentry in $c//childentry return replace value of $childentry/@id with concat('New Child: ', data($c//childentry/@id))
To modify the child entries like so:
<childentry id="1"> ----- > <childentry id="New Child: 1">

Christian,
Yes. I did realize that I must use a RETURN statement. I tried that with a slight change in the requirement. Say, my child entries look like so :
<childentry id="1" />
I tried:
for $childentry in $c//childentry return replace value of $childentry/@id with
concat('New Child: ', $c//childentry/text())Does replace work differently for attributes ?
Thanks, Sony

Sony,
each FLWOR expression needs to be completed with a RETURN statement. Please insert the following snippet (haven't tried it live):
for $childentry in $c//childentry return replace value of $childentry with concat('New Child: ', $c//childentry/text())
Hope this helps, Christian ___________________________

Christian, Thank you very much for helping me with the query. However, I am not
quite
sure how the transform operation works if I have to use a for loop.
Say, I
twist around yesterday's question a bit like so: copy $c :=
<entry> <id>1</id> <title>How to use a transform expression</title> <updated>2011-02-23</updated> <author> <name>BaseX Team</name> <uri>http://basex.org</uri> </author> <childentry> 1 </childentry> <childentry> 2 </childentry> <childentry> 3 </childentry> <content type="html">Transform expression example created by BaseX Team</content> </entry> modify ( replace value of node $c//name with 'BaseX', replace value of node $c//content with concat('Copy of: ',
$c//content),
insert node <member>Joey</member> into $c//author for $childentry in $c//childentry replace value of $childentry with concat('New Child: ', $c//childentry/text()) ) return $c
The expected output is:
<entry> <id>1</id> <title>How to use a transform expression</title> <updated>2011-02-23</updated> <author> <name>BaseX</name> <uri>http://basex.org</uri> <member>Joey</member> </author> <childentry> New Child: 1 </childentry> <childentry> New Child: 2 </childentry> <childentry> New Child: 3 </childentry> <content type="html">Copy of: Transform expression example created

</entry> The following exception is thrown when I tried my sample
transformation
query with the for loop: [XPST0003] Expecting 'where', 'order' or 'return' expression. Thanks, Sony PS: @Lukas: I did notice the update in the documentation. Thank you !
