Why do you want to put this in setupinteractionscreen? It doesn't
belong to interaction in any way. Why not make it separate macro? Say
\setuppdfoutput[...].

BTW, keywords can already be defined anyway with pdftex's \pdfinfo as most of
you probably know. But it is not `The ConTeXt way' of doing it, that's for
sure ;)

This command gives a different sized paper (wider 261.4x297 rather than A4)
and does not do what Tobias and I wanted ie fitting to width.

maybe i should indeed add such an eraser

sorry for misunderstanding you requirement, this it the way:

\defineXMLargument [url] [href=] \Url

Ah, then why not init the attribute each time and use the shorter \XMLop 
(own parameter):

   \defineXMLargument [title] [label=] {\chapter[\XMLop{label}]}

best combine this with:

   \setuphead[chapter][expansion=yes]

An unreadable alternative (just illustrating expansion is):

\defineXMLenvironmentpush [title] [label=]
   {}
   {\expanded{\chapter[\XMLop{label}]{\XMLflush{title}}}}

Hi,

> I need something like a \XMLeraseAttribute{url}{href}.

Ok. I found a solution:

\unprotect
\def\XMLeraseattr#1#2{\@EA\let\csname\@@XMLvariable:#1:#2\endcsname\undefined}
\protect

\setupcolors[state=start]
\setupinteraction[state=start, color=blue]

\def\Url#1{%
    \useURL[c][#1]%
    \useURL[h][\XMLpar{url}{href}{#1}]%
    \goto{\url[c]}[url(h)]%
    \XMLeraseattr{url}{href}%
}
\defineXMLargument[url]\Url

\starttext
\startXMLdata
<url>ONE</url>
<url href="foo">TWO</url>
<url>TREE</url>
\stopXMLdata
\stoptext

Hi Hans,

> \defineXMLargument[url]\TobiasURL
> it's element content, not an attribute!
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.

since this has been requested before we've reached a critical mass -)

next release will have

keyword=...

(singular but one may give a,b,c,d)

Ah, i see:

\def\TobiasURL#1{\doifsomething{#1}{URL:#1}{no url given}}

\defineXMLargument[url]\TobiasURL

it's element content, not an attribute!

alternatively you can do an

\defineXMLenvironmentsave [url]
   {\XMLerase{url}}
   {so something with \XMLdata{url} ...}

Did you try:

\setupinteractionscreen[width=fit]

I'm also interested in a solution for this, because I tried

\setupinteraction[keywords=keyword1 keyword2,
                  ...
                 ]

without success :-(

%This should be ok, I think
\def\Url[#1]#2{Href:#1 / text:#2}

% Now I have \expanded{\Url} it should work, shouldn't it?
\defineXMLargument[url]\expanded{\Url[\XMLpar{url}{href}{DEFAULT}]}

\expanded{\somecommand stuff to expand}

so, expanded takes an argument! and the first thing in there is not 
expanded, you forgot the {}

It still doesn't seem to work :-(
---------------- This -----------------
\def\Url[#1]#2{Href:#1 / text:#2}
%\def\Url#1{{\useURL[foo][[\XMLpar{url}{href}{#1}]\goto{\url[foo]}[url(#1)]}}
\defineXMLargument[url]{\expanded\Url[\XMLpar{url}{href}{DEFAULT}]}

\starttext
\startXMLdata
<url>a link</url>
<url href="foo">another</url>
<url>a third</url>
\stopXMLdata
\stoptext

------------- produces ----------------
Href:DEFAULT / text:a link Href:foo / text:another Href:foo / text:a
third

I have three additional problems (with version 2002.3.27/beta):
* In the bookmarks/documentinfo of Acrobat Reader the umlauts are
followed by {}, e.g.
  Eine Ü{}bersicht
* clicking on a link, the page is "fitted to window"
  how can I set it to e.g. fit to width?
  (as openaction, I know how to do so, but for links/bookmarks?)
* How can I set the keywords part of Acrobat's "Document Info"?
  Since our indexer can use this information, I'd like to use it.

so, by expanding you fix the values

ConTeXt XML question

[Tobias Burnus]

Hi,

(Sorry for the only half send text I had mailer problems. I did a copy and
past, but there must have been a ^X somewhere in between.)

I somehow have problems with \XMLpar

I have
 <url href="foo">bar</url>
 <url>http://www.bar</url>
In the first  case I want to get a link with the destination given in
href.
In the second case I want to get a link with the same destination as the
<url> enclosed text.
But I get in both cases HREF:foo. If I switch the order I get "XXXX" and
then "foo"which I had expected. (ConTeXt  ver: 2002.3.4)

I tried:
\def\Url[#1]#2{{HREF:#1 URL:#2}}
\defineXMLargument[url]{\Url[\XMLpar{url}{href}{XXXX}]}
