Hi,
can someone give me a helping hand with the following example. I still
have no general survey over the XML related code in ConTeXt (donno
what functions to use). The last time I played with it is one and a
half year ago and many things have changed (meaning that the old
examples no longer work).

oeps, how could I missed that one... :(
I simply want to create a XML document and insert some elements. My
main problem is to insert an element at root level. I can insert an
element before and after another element, but not into the element.
I'm not sure, if I have understood the meaning of the pattern
parameter correctly. Is this equal to XPath?

\starttext
\startluacode
local xmp = xml.convert("<?xml version='1.0'
standalone='yes'?>\n<root>\n<bar>bla</bar>\n</root>")
--xml.before(xmp,"/root/bar","<sub>foo</sub>")
--xml.delete(xmp,"bar")
--xml.inject(xmp,"/sub","<sub>bar</sub>")-- only for xml-files?
xml.insert(xmp,"/root/bar","<sub/>")
--xml.inject(xmp,"/*/bar","<sub/>")
this works

Mhh, not here. When I look into the saved file (test.xml) I get
add some content (i need to look into the empty case (root only))
<?xml version='1.0' standalone='yes'?>
<root>
<bar>bla</bar><error>invalid xml file - unparsed text</error>
</root>
But I guess that the linked PDF will give all the answers I need.
the most important change is that we now can have many handlers; when
you are inside tex and want to manipulate xml without piping to tex, you
need the xml:// path prefix but the manual mentions this
also, there are some tracing options that can be handy
