I need to parse an XML document in java for a web service I'm making, and save the contents of it.
I need to save the name of the tags, if the tag has attributes save the attributes, and then save the data within those tags. These three items will be inserted into a database table with the three columns tags, attributes, and data.
I'm using the following java libraries:
javax.xml.parsers.DocumentBuilder
javax.xml.parsers.DocumentBuilderFactory
org.w3c.dom.Document, org.w3c.dom.NodeList
org.xml.sax.InputSource.
Any help would be much appreciated.

DISCLAIMER: I don't want to plagiarize so I didn't include code but included links to other tutorials that are VERY helpful to this topic.
First, you should read w3c dom's java API because it tells you a lot of useful functions that are very related to your question.
Second, this website contains a useful tutorial that's easy to understand and it contains the necessary information for you to get the attributes of tags.
Third, this website gives you info on how to get tagName when you are looping through elements.
Fourth, you should always read related API, google, and then post a question if you are have no clue after a LONG period of time.
Lastly, you should post a difference question or research on database FIRST before asking that question here. This question should only be about XML Document Parsing in Java.
We are not supposed to help you do anything so the API is the best help for you (and google).

I have a xml reader which reads the title and the name of a person in java from a rss feed. I accomplish this by using document builder in java. When I read the element title and element name, I put them into a concurrent hashmap. This is fine, I can get the values from the map. However I want this information to be stored there for some time limit and not call the document builder until this time limit has passed. But the problem is when I do not call the document builder and refresh the webpage my hashmap values seem not to be stored. Code is in java and wicket.
Thoughts ?

It may be that every time you're refreshing the page a new hashmap is built and the old one is simply discarded. You should make sure your data stays persistent.

Is there an easy way to create a method that enables you to take the date of a file's creation and append it to the front of the file name? Example is a file named blah1.doc that was created on December 4, 2010 be rename to 2010124blah.doc.
If that is possible, is there a way to sort the files based upon creation date and copy them to different folders based upon filename?

Since some Linux systems do not support creation timestamps, this is not always doable.
Use Java nio if you are working on a system that does provide timestamps.
Path file = ...;
BasicFileAttributes attr = Files.readAttributes(file, BasicFileAttributes.class);
// create new file object
newFile = new File(attr.creationTime() + ".doc");
// rename file
oldFile.renameTo(newFile);

I am looking for an open source dictionary, The user in my application enter city name in Hebrew, and I want to translate it to English. I have another component that can use only English city names.
Where can I find such a component?

I guess that your main problem is not how to match Hebrew names to English ones (once you have a list of pairs), but actually how to obtain the data of matchings between Hebrew and English names. I'll also guess that you are aiming for cities in Israel if you are speaking about hebrew names. Therefore I'd try the statistics from the central bureau of statistics - they have a table with hebrew city names, and their english corressponding names. You can find it here: http://www.cbs.gov.il/ishuvim/ishuvim_print.htm

Did you try to use one of the Map implementations? For example HashMap or TreeMap? I'd even say more: just store all localized names in resource files (properties format) and use ResourceBundle to access them.
for example call your file towns.properties
tel-aviv = Tel Aviv
jerusalem = Jerusalem
The Hebrew version of your file is towns-iw.properties
tel-aviv = תל אביב
jerusalem = ירושלים
Now using ResourceBundle API create Map that contains direct associations between English and Hebrew names. Then just use it.

Somewhat related to this question, but in the absence of any answer about QuickBooks specifically, does anyone know of an address parser for Java? Something that can take unstructured address information and parse out the address line 1, 2 and city state postal code and country?

I do know that the Google Maps web service is great at doing this. So, if you want to use that, you could save a lot of effort.
The real issue here is that you need a worldwide database of city/country/province names to effectively parse UNSTRUCTURED addresses.
Here is how I build a URL for use by the Google Maps API in C#:
string url = "http://maps.google.com/maps/geo?key=" + HttpUtility.UrlEncode(this.apiKey) + "&sensor=false&output=xml&oe=utf8&q=" + HttpUtility.UrlEncode(location);

The SourceForge JGeocoder has an address parser that you may find useful. See http://jgeocoder.sourceforge.net/parser.html.

Might want to read this Stack Overflow question:
"Parse usable Street Address, City, State, Zip from a string". No actual Java code to do the job (just some VB), but there is some discussion of the problem and more info on the alternative John Gietzen mentions, of using a web service to interpret it for you.

The Mural project has an address parser: https://mural.dev.java.net/. I haven't figured out how to exract it from the larger Mural engine, but it does work based on some very limited tests.

See www.address-parser.com, they offer a web service for parsing international addresses.
