DTD and DomParser
Please help a newbie who can't find it in the docs
How do I specify a DTD to use with a DomParser instance?
Where does it look for the dtd? local directory?
Does it need a fully qualified path?
Help!
Thank you

I'm afraid that's not possible by defintion.
You can have either well formed standalone XML document without a DTD at all
or you supply the DTD file using DOCTYPE directive. If you say
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<myroot>
...
</myroot>
The XML parser in this case can check only whether the XML document
is well formed and that's it.
On the other hand in Xerces-C is possible to reuse DTD for multiple XML
files which follow the same DTD definition. They can't have internal DTD
subset in this case. Please look at the FAQ and/or archives for this topic.

See the response that Julia posted to her own question. The
InputSource interface has both setPublicId() and setSystemId(). You
can apparently use these to create input sources and then set DTD's
for xml chunks without DOCTYPES.

If the DOCTYPE is not in the document, is there a way to tell the DOMParser
to parse some dtd file before parsing the actual file?
Thanks,
Patrick

Supply a DOCTYPE, e.g. :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE myroot SYSTEM "myschema.dtd">
<myroot>
...
</myroot>

You can supply the fully qualified path or relative path.
In the example above it will search for the file myschema.dtd in the
directory where the file is sitting.
Hope this helps

You don't. The XML file you are parsing specifies using the DOCTYPE,
either with PUBLIC or SYSTEM. Then it is up to an entity resolver to
find it and give it to the parser.
