User specified XML parser features and xinclude [message #228440]

I'm using eclipse 3.4.1 & WST 3.0.2 (which uses xerces 2.9.0).

I can enable XInclude processing via eclipse preferences which is good and
works well, except in my case I need to specify additional parser features
to disable the lang and base fixup by the parser. Currently the UI only
allows enabling XInclude, and not any of these other features that Xerces
supports.

So my main question is:
Is there a way to specify additional xml parser features to be used?
If not, can I tell eclipse to use my own parser instead?

I haven't found that Xerces by itself supports specifying features from
properties (to my surprise) and I can't find any eclipse mechanism for
this either. Ideally eclipse would have a global xml parser feature set
and I could then enable project-specific parser features on. I'd even be
happy if I could at least just specify a properties file that lists parser
features and tell xerces/eclipse to use it somehow. In my RCP application
I have my own parser which defaults many xml parser features to be set the
way my application needs them to be given my schemas (e.g. enable
xinclude, don't fixup lang and base uri, etc), so in the end I'm just
trying to get eclipse to validate my xml files the same way my RCP
application does.

Currently you can't specify these additional options. Open an
enhancement request for this.

You would need to contribute your own Validator to be used. Much of
Eclipse in WTP is hardcoded to use Xerces.

You might also want to look at the XInclude ant task that is included in
XSL Tools. It also leverages Xerces, and the source for it is much
easier to understand. Patches to it are encourged and welcomed.

But your best bet is to create a custom validator that uses your pacific
parser instead of the built in validator that WTP supplies.

Thanks for the info. I couldn't find any related bugs regarding XML
Validators so I submitted bug 266392: https://bugs.eclipse.org/266392
