Parsing an XML inside a zip in-memory

Question

I have a Zip that contains two files: an XML and a thumbnail. I would like to open the XML file and parse it WITHOUT having to extract on disk.

One of DocumentBuilder's parse method requires an InputStream. Is there a way to get the InputStream of the XML in the Zipped file? I kinda got lost. I'm pretty sure ZipInputStream or ZipFile has something to offer, but I can't figure it out :/

Thank you in advance!

I believe you're looking for something like this:

FileInputStream fin = new FileInputStream("your.zip");
ZipInputStream zin = new ZipInputStream(fin);
ZipEntry ze = null;
while ((ze = zin.getNextEntry()) != null) {
    if (ze.getName().equals("your.xml")) {
        // pass zin to DocumentBuilder
    }
}
