Can XMLBean parse multiple XMLs?
Hi, All,
I have multiple XML files related through my own <import> tag. These files
share same schema. This is used to support content sharing and inheritance
like features. Put another way, it is like <import> tag in Ant build file.
Can XMLBean load and parse multiple XMLs at one time? If not, I will try to
concatenate multiple XMLs into a single file based on <import> tag, then use
XMLBean to parse. Or is there a better solution?
Thanks in advance!
Bo
Re: Can XMLBean parse multiple XMLs?
Posted by Bo Wen <bo...@gmail.com>.
Hi, Jacob,
Thanks for your thought. The reason to split them into multiple files is to
share content. For example, I may have the following "import" chains:
File A <-- File B <-- File C (B imports A and C imports B)
File A <-- File B <-- File D (B imports A and D imports B)
File A <-- File E (E imports A)
I am doing read-only parsing only for these XMLs and do not want to
duplicate A's content to other files.
Another thought is whether I can use XLink to refer to an external XML with
XMLBean. I am new to XMLBean and looking into possible solutions.
Thanks for the help again!

Re: Can XMLBean parse multiple XMLs?
Posted by Jacob Danner <ja...@gmail.com>.
Hi Bo,
I guess the complete answer is there is no EASY way to do this. You
might be able to HACKHACK something together using XmlCursor APIs like
XmlCursor.copyXml(...) or copyXmlContents(...).
I've gotta wonder if maybe you aren't making this more difficult on
yourself by not using standard XML features.
If you've designed your schema as such you might be able to do
something like this:
<xsd:element name="composite">
...
<xsd:element ref="aType"/>
<xsd:element ref="bType"/>
<xsd:element ref="cType"/>
...
File AXml = // <a />
...
AType AXmlInstance = AType.Factory.parse(AXml);
...
CompositeDocument c = CompositeDocument.Factory.newInstance();
c. /// other init stuff
s.setAType(AXmlInstance);
s.setBType(BXmlInstance);

Thanks Jacob! So there is no way to parse multiple XMLs through XMLBean and
I have to concatenate them. It would be nice if XMLBean could do that.

Hi Bo,
This will not work as a new XmlObject (think xml instance) is created
on each call.

If you concatenate into one instance that should work.

Re: Can XMLBean parse multiple XMLs?
Posted by Bo Wen <bo...@gmail.com>.
Thanks for the reply. You are right. <import/> is just a normal tag and
from my own schema. I don't expect any parser understand that. I will need
to manually load all imported files into memory and treat them as a single
XML in memory for navigation. I will have to write special logic to
interpret <import/>.
For example, File A imports File B and File B import File C. I want to load
File A, B and C together into memory as a single XML. So, can I do this:
XmlObject.Factory.parse(FileA);
XmlObject.Factory.parse(FileB);
XmlObject.Factory.parse(FileC);
Will this load 3 XML files into memory as a single XML?
If not, as a workaround, I can do pre-process: concatenate File A, B and C
into a single File X based on <import/> tag. Then use
"XmlObject.Factory.parse(FileX)" to load it into memory for havigation. Or
is there a better way?
I am curious how Ant does this for its multiple build files using
<import/>. I am sure Ant does not use XMLBean.
Thanks,
Bo

Hi Bo,
I'm not sure I completely understand the question, but I'll give it a shot.
If you are trying to do something like
XmlObject.Factory.parse(<instanceDocument/>);
My guess is your <import /> tag won't work as you expect it to because
its not part of the normal XML grammar (AFAIK) and the parser won't
know what to do with it.
Do you know of another parser that works with this? In other words,
how are you making your <import /> element work currently?
Thanks,
