getElementById

[Marc Dzaebel]

Hi,

using JDK1.6, is there a way to tell a Document (DOM Level 3) that a certain
Attribute (usually "id") is always of type ID without defining a grammar
file? Currently I have to traverse the full DOM tree and
setIdAttribute("id", true). Otherwise getElementById returns null. If I need
a schema, is it possible to create it programmatically.

Thanks, Marc

I don't know whether the parser you use supports that but xml:id could
help, see
<http://www.w3.org/TR/xml-id/>
That way you do not need a DTD or schema (but you need to use the
attribute name xml:id).

Hi Martin,

I already tried this but obviously the use of attribute name xml:id does not
work, even if the parser (Xerces) is set to be namespace aware. May be
Xerces does not implement this newer recommendation yet?

Thanks, Marc

Sounds likely. Xerces has its own mailing list; ask there? (Or check
their website; they *should* list the specifications they support
somewhere, though that may not have been updated recently.)

I just verified that Xerces does *not* support http://www.w3.org/TR/xml-id/.
