Re: [basex-talk] RESTXQ generated HTML - unexpected behaviour

Could you help me fully understand the reason - so why /exactly/ is %output:method("xhtml") essential? I would have thought that the reason is fully given by the serialization details. But from what you wrote I gather there is a second reason, which is the content-type header which is set dependent on %output-method? After reading your post I also found in the BaseX documentation: "The next function, when called, generates XHTML headers, and |text/html| will be set as content type:" As far as I have understood the BaseX documentation for REST and RESTXQ, the default content response type for a GET request is application/xml, so for your GET where you want to return XHTML to be treated as text/html, you need to use one of the ways to ensure that the content response type is text/html, the easiest I have found is to add the %output:method("xhtml") annotation.

I have not tried your code but if JavaScript fails in one result document but not in another then one reason could be that the JavaScript is written for text/html documents (as which static .html or htm documents are ususally served) while the code does not work right with XHTML served as application/xml or application/xhtml+xml. So I would first check whether your RESTXQ where the script doesn't work is served as text/html or with an XML MIME type like the two ones I have mentioned, in the latter case I would indeed expect script attempts like a = document.createElement("DIV") to fail to achieve to create the right element as X(HT)ML is case-sensitive and works with a namespace so you would rather need a = document.createElementNS("http://www.w3.org/1999/xhtml";, "div") in an X(HT)ML served with an XML mime type context. So I think your XQuery code lacks %output:method("xhtml") e.g. declare %rest:path("/demo-autocomplete") %rest:GET %output:method("xhtml") function f:demoAutocomplete() as element() {
