Hi all, I'm currently trying to generate XML documents with HXT. Everything went well but I can't figure out how to generate the "xmlns:..." attributes for the namespaces. My code looks like: runX $ constA (request TableListRequest) >>> root [] [writeA] >>> writeDocument [(a_indent,v_1)] "-" where writeA generates the actual content. This code generates something like: <?xml version="1.0" encoding="UTF-8"?> soapenv:Envelope soapenv:Body request:tablelist/ But I want it with XML namespaces, i.e.: <?xml version="1.0" encoding="UTF-8"?> http://schemas.xmlsoap.org/soap/envelope/" xmlns:request="http://www.officematic.de/domas/request" > soapenv:Body request:tablelist/ I tried using "uniqueNamespaces" and "uniqueNamespacesFromDeclAndQNames" but neither worked. Maybe I used them in the wrong part of code. The tree representation my document looks like: ---XTag "/" | +---XTag "{http://schemas.xmlsoap.org/soap/envelope/}soapenv:Envelope" | +---XTag "{http://schemas.xmlsoap.org/soap/envelope/}soapenv:Body" | +---XTag "{http://www.officematic.de/domas/request}request:tablelist" and for me this looks like if there is enough namespace information provided. I would appreciate any help, Martin.
