How do I generate hyperlinks for URLs in PDF output?

For example like this:

\useURL
  [context]
  [http://www.pragma-ade.com]

And don't forget to

\setupinteraction
  [state=start]

start the interactive mode.

I got the general idea, but can't get the following peace of code do
what I want (surely due to my poor TeX/ConTeXt knowledge):

- given a peace of XML like:

  <ulink url="http://www.somewhere.net">some site</ulink>

- I want to map this XML to ConText hyperlinks like:

  \def\makeulink#1{%
    \useURL[one][\XMLpar{ulink}{url}{}]%
    \goto{#1}[URL(one)]}
  \defineXMLcommand[ulink] \makeulink

Two unsolved issues remain:

- only the first character of the XML element text ("s") is taken as the
  hyperlink text

- given the fact, that there might be many <ulink>s, do I need unique
  names for \useURL ("one" in the example) or can I reuse the same name
  for all instances?

I suppose \goto can take a url directoryl, so you don't have to use
\useURL. Have you tried this?

\useURL has four commands:

\useURL
  [ufdhc]
  [http://www.eiffel-forum.org/archive/dominicu/fdh.htm]
  []
  [Unix File/Directory Handling Cluster]

The 4th is the replacement text, so you get the text, and not the
URL. If the 4th is not provided, you just get the url.

It does not work, I have to use \useURL. 
Multiple instances of the same label for \useURL seem to work, at least 
I did not get any errors in processing a document containing many <ulink>s.

The probem was

\defineXMLcommand[ulink] \makeulink

it has to be

\defineXMLargument[ulink] \makeulink

you need \defineXMLargument here

also, make sure to create a namespace, so \SOMETHINGmakeulink or so

you can reuse the symbolic name, and in case of temp ones, use [dummy]
