Well that's not exactly what I want.
I try another example (see "XML in ConTeXt", page 13):
-------------------------------------
\version[temporary]
\defineXMLenvironment [text] {\starttext} {\stoptext}
\defineXMLargument [title] {\chapter[\XMLpar{title}{label}{}]}
\defineXMLgrouped [tt] {\tt}
\startXMLdata
<title>First chapter</title>
<title label="second">Second chapter</title>
<title>Third Chapter</title>
<?context-command {See also \in{chapter}[second]} ?>
\stopXMLdata
\bye
-------------------------------------
In this case I get the warning:
references : duplicate reference [][second] on page 3 (test2)
That is I get behind the scenes:
\chapter[]{First Chapter}
\chapter[second]{Second Chapter}
\chapter[second]{Third Chapter}
But the latter should be '[]' not '[second]'

Back to my problem. The URL syntax I need to use is:
<url>http://www.foo.com</url>
and
<url href="http://www.bar.com";>The best Bar on the planet</url>
This should produce a
\goto{http://www.foo.com}[url(http://www.foo.com)]
and
\goto{The best Bar on the planet}[url(http://www.bar.com)]
respectively.
(The reason is that <url> gets usually a URL (=>use element content),
but sometimes only a descriptive content (=> then use the href
attribute).)
This fails since as soon a {url}{href} is set, it doesn't get reset
anywhere.
I need something like a \XMLeraseAttribute{url}{href}.
By the way I tried the \XMLdata{url} and it produced always "url" as
output. But that's another bug.
