[basex-talk] do not interpret text nodes as embedded expressions (Expecting '}' but found...)

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!
