I need to iterate .xml files in a directory, once I have a handle to the file I will get a read stream and do other things which I'm fine with - just need a quick and dirty way to iterate the files in the directory.  I'm using Java and DOM4J so if I can do it within those packages it would be great.

Thanks in advance.

CEHJ is right.
And in case you wouldn't know how to iterate:

File dir = new File("somedir");
File[] myFiles = dir.listFiles(new FileFilter() {
    public boolean accept(File pathname) {
        return pathname.getName().toLowerCase().endsWith(".xml");
    }
});
// Iterate through your files:
for (int i=0, m=myFiles.length; i<m; i++) {
   File theFile = myFiles[i];
   // Do with your file what you want...
}

>> zzynx's iteration tip helped
Then I wonder why I'm not part of a split
(And I also wonder what the comment should have been to deserve an A grade?)

ok can we do that - I couldn't figure out how to split the points - that's why I gave them all to CEHJ.

Also I'd like to change the grade to A also.

Thanks.

I'll ask to reopen this Q.
Once reopened you can close it again using a split

>> I couldn't figure out how to split the points
Here's what EE's halp page says about that:

Can I split the points?
Yes. Scroll down to the bottom of the question, just above the text box, and click the "Split Points" link. Select the radio button of the comment who you want to Accept as the Accepted Answer. Only one button can be selected. Set the point value (a text box above the comment) of how much you want this person to receive of the points. Then set the point values for each of the experts comments to whom you want to allocate points and these will be considered Assisted Answers in helping you resolve the issue. Double check your information and then click the Submit button at the bottom of the page. One note: the total points of the splits must equal the amount you asked the question for itself, and no person can receive fewer than 20 points.
