Looping through attributes

Rate this Message:
Hello folks, There is one thing bodering me and I hope someone could help. When I loop through attributes to search for values. How do I stop jdom from not printing on any attribute that it loops through. Example: I search for an attribute "domain" when the corresponding value matches jdom returns found. But when not found; it prints on all attributes and I get a list of not found, not found, corresponding to the number of attributes in the documents. What code or how do i tell jdom to print "not found" only one time? Bashiro Drammen-Norway _______________________________________________ No banners. No pop-ups. No kidding.

Show us your input, show us your code, and we can help you understand where you have gone wrong. JDOM doesn't do anything unless you ask it to.

I can't see why you aren't using getAttribute() to get the attribute by name, which would surely be much simpler. But your actual bug is that you are executing the "else" code ("Domain does not exist") once for every non-matching attribute (it's inside the while loop). A dangling else bug. Take more care over indentation in future.

You surely don't want JDOM to display the message, you want to do it
yourself. Isn't it just Attribute att = element.getAttribute(name); if (att == null) { display message; } or have I missed the point?

Hi

To have a boolean variable 'found' initialized to false before the loop, set it to true on find and use 'break' instead of 'return'? Just a suggestion.

No :).
boolean found = falsefor (...) { if ("domain".equals(...)) { ... found = true; break; }} So not found will be displayed once. But better use Michael's way, it is ok. String value = element.getAtttibute("domain");if (value == null || (!value.equals(dom.trim()))) display "not found" Regards,Grzegorz 2008/1/22, Bashiro <bashiro@...>:>>> Thanks,>> Theoriticaly yes, but practically no!> When boolean is false, that is when the value of an attribute is not found,> jdom displays as many "not founds" as the number of contens in the xml.>> I am beguining to think if I should combine HashMap so that Hashmap will check before passing it on to the jdom code.> I thought jdom could do this easier....>> Bashiro> Drammen-Norway>>>>> --- On Tue 01/22, Grzegorz Kaczor < grzegorz.kaczor@... > wrote:> From: Grzegorz Kaczor [mailto: grzegorz.kaczor@...]> To: bashiro@...> Cc: jdom-interest@...> Date: Tue, 22 Jan 2008 20:33:37 +0100> Subject: Re: [jdom-interest] Looping through attributes>> Hi>> Thanks for the mail.> And thanks for warning me about the else clause.> Do you have any suggestions on how to let jdom> display a message when the attribute is not dound ?To have a boolean variable 'found' initialized to false before theloop, set it to true on find and use 'break' instead of 'return'?
