Re: [Mxquery-xqib] Using XQUERY in Javascript via variables

Yes, your expression looks for element nodes within a string value. That won’t work. You would need to find a way to parse/unquote/unescape the value first. I am not sure mxquery has such a feature yet. A workaround for that could be to use JS to inject the value into the HTML DOM, and thén retrieve that through the b:dom function. Untested though..

However, to write it, you will need a library function that evaluates a string containing XQuery code. I am clarifying whether MXQuery has such a function, and if it can take XML input, and will get back to you when I know more. I hope it helps? Thanks for your interest in XQIB and kind regards, Ghislain On Apr 24, 2013, at 12:07 AM, ousta ousta <ous...@gm...> wrote: > I saw the sample using xqib.call to call some xquery code in javascript. > > My need would be somewhat different.
