Hi,
I am wondering if there is a way to convert a String into a Node within XQuery.
For example, consider the xquery
let $node := copy $c := <entry> <title>entry title</title> <content>entry content</content> </entry> modify ( return replace value of node $entry/title with 'new entry title', return replace value of node $entry/content with 'new entry content' ) return $c
return replace node doc('doc1')/entry with $c
The above xquery throws the error: [XPTY0019] Context node required for entry; xs:string found. How do I fix this ?
Thanks, Sony
Sony,
please provide complete queries, otherwise it's difficult to give constructive feedback (e.g.: $entry isn't specified anywhere, etc).

Hi Christian,
The complete query is:
let $node := copy $c := <entry> <title>entry title</title> <content>entry content</content> </entry> modify ( return replace value of node $c/title with 'new entry title', return replace value of node $c/content with 'new entry content' ) return $c return replace node doc('doc1')/entry with $node
Note: doc1 is a document in the database with 'entry' as the root element.

…still incorrect; "return" before "replace" doesn't make sense. C.

Yes, I tried the query without the return earlier. I saw a syntax error: [XPST0003] Expecting 'where', 'order' or 'return' expression.
I return $c in my query but I still see the error. Looking at the error, I guessed that when a transform function is used in a query, return is required to replace.
Also, I am using two return statements inside the modify function. I am not sure if that is allowed. In any event, is there a way to update multiple nodes at the same time with or without using modify.
Thanks, Sony

Edited the xpath in the query. The final xquery looks like so:
let $node := copy $c := <entry> <title>entry title</title> <content>entry content</content> </entry> modify ( return replace value of node $c//title with 'new entry title', return replace value of node $c//content with 'new entry content' ) return $c replace node doc('doc1')/entry with $node
This does not work.

Please check beforehand that your queries don't contain obvious syntax errors like the one above. This can be easily accomplished by copy-pasting them into the BaseX GUI [1], which highlights errors quite nicely.
This does not work.
Try deleting both 'return' keywords in the 'modify' clause and adding one at the beginning of the last line. And please keep in mind that this mailing list should be primarily about BaseX, not XQuery syntax.

Thanks. I realized the syntax error a couple of minutes ago. I was trying out a more complex example meanwhile.
