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
