With the following example, the output xml writer fails to properly transform & to the html entity & in some urls; \hyphenatedurl works fine. The generated xhtml and html files have this problem as well as more issues with the transformation, including what appears to be mistaken transformation of < and > to html entities and unbalanced <link> tags. When a URL without & is used, the problems do not appear. I used the default export-example.css file, and I assume that the lack of interaction in the result reflects the lack of coding for links in that file. This was tested with the 2014-08-27 standalone. \setupbackend[export=xmltest.xml,xhtml=xmltest.xhtml,css=export-example.css] \setupinteraction[state=start] \useURL[avecAmpersand] [http://www.mail-archive.com/search?l=ntg-context@ntg.nl&q=Epub] [][klik hier] \starttext \startsubject[title=Fails in xml] \startparagraph \tex{from}: \from[avecAmpersand] \stopparagraph \startparagraph \tex{goto&[url]}: \goto{klik hier}[url(http://www.mail-archive.com/search?l=ntg-context@ntg.nl&q=Epub)] \stopparagraph \stopsubject \startsubject[title=Okay in xml] \startparagraph \tex{url}: \url[avecAmpersand] \stopparagraph \startparagraph \tex{hyphenatedurl}: \hyphenatedurl{http://www.mail-archive.com/search?l=ntg-context@ntg.nl&q=Epub} \stopparagraph \stopsubject \stoptext -- Rik Kabel
