read zipped files without unpacking?

Hi,

I want to get the source code from openOffice files, in plain xml. Now,
I've installed the whole openOffice API, but this is to actually work with
the file itself. What I want, is to get the plain xml code. When opening an
openOffice document with winrar, I see that there are a few .xml files that
can be used. Now is the question: how can I open such a zipped openOffice
file in java and read the source xml code? This should be done, without
unpacking the files to the users hard disk...

thanx,
Tim

use Zip or exec Winzip or PkZip if the compression algorithms used are
unsupported.

java.util.zip.ZipInputStream should work.

that unpacks each one in sequence. You want Zip to pick and choose
what you want.

And how do I do it your way? Is this a class I can use or something? Do you
have a URL where there's something explained? Try entering "java zip" in
google, and you're flooded by unusefull information. :-s

thanx in advance
Tim

See
http://java.sun.com/j2se/1.3/docs/api/java/util/zip/ZipInputStream.html
for the API.

You did not say if your files were local or remote, or if they are the
in the resource jar.

See http://mindprod.com/jgloss/jar.html
see http://mindprod.com/jgloss/zip.html

the java.util.ZipFile class is what you want if they are local. See
the Javadocs for it.

I agree the OP may find that class more useful. OP, see
http://java.sun.com/j2se/1.3/docs/api/java/util/zip/ZipFile.html for the
API.
BTW, I checked that jar -t and jar -x, which probably use the same
underlying Zip file processing routines as these Zip I/O classes, work
on a sample .sxw file.
