Hi all,
How can I process this query in basex:
let $x := doc(<a>main(){int i = 0;}</a>)
return replace value of node $x with ""There are text contents that contain, for example, c code with curly braces which I do not want to be interpreted as embeded expressions.
As a workaround I could escape the curly braces, But, is there a better way/option to suppress interpreting text contents that look like embedded expressions?
Thanks!

Maybe with a CDATA section?
let $x := doc(<a><![CDATA[main(){int i = 0;}]]></a>)
return replace value of node $x with ""M.

Sorry, all, here is a more specific question:
The query is constructed at runtime and executed using the QueryProcessor command.
Query: replace node . with <a>main(){int i=0;}</a>
Execution error: Expecting '}' found ...
If I try to bind the replacement as a global parameter, the error message is: Single element, text, attribute, comment or pi expected as replace target.
The java code:
QueryProcessor query = new QueryProcessor("replace node . with $replacement",
context);
query.bind("replacement", "<a>main(){int i=0;}</a>");The problem with escpaing the curly braces (or wrapping all text content nodes and maybe attribute values, too) is the extra overhead which would decrease performance.

Erdal,
Escaping the curly braces by doubling them would be the "normal" way. You ask for a better way; can you be more specific as to what needs to be improved? Would this be an improvement?
let $expr := 'main(){int i=0;}'
let $x := doc(<a>{ $expr }</a>)
return ...Cheers, Wendell

FYI: solved using parse-xml():
QueryProcessor query = new QueryProcessor("replace node . with
parse-xml($replacement)", context);
query.bind("replacement", "<a>main(){int i=0;}</a>");2013/10/18 Erdal Karaca <erdal.karaca.de at gmail.com>
