A program to convert text files from one specification to another

[James Ogar]

Please can any one help? i was ask to write a program in Java to convert .xml, .dat, .html, add., and .txt (they are all compress files in different folders)format to XML format.

Requirements to output specification

Format XML, which want to convert

Note
After conversion - each patent must be in a separate . Xml file. Files must be placed in folders that correspond to the names of files. After converting another archive - archive the resulting file folder , leave the archive and delete the folder itself . If you will not do that - then you eventually get 600 gigabytes . When archiving , use the "-mx = 9" for 7z for maximum compression .

After the write converter - convert time to vote the entire array, as well as the total amount of the resulting file (in compressed form). Total there are about 10 million patents

please i would appreciate it if any one can provide me with assistance

This sounds like homework. Think about how you would design it and post that for feedback. Or ask about which part of the assignment you are stuck on.

Yes, yes i need some guide please

[William Brogden]

Harold's free online book is loaded with examples of doing various XML related jobs with JAVA.

1) turn off your compter.
2) get paper, pencils, and erasers
3) work out in English, Spanish, Russian, French, German or whatever natural language you prefer how to do it, step by step
4) Revise those steps, adding in details and clarity.
5) repeat step 4 until you could hand the directions to a 10 year old child and expect them to be able to follow your steps
6) ONLY when the above steps are complete should you consider writing a single line of java.

Looks like Russian to me

Creating the XML is probably not the major problem. Extracting structured information from various sources formats is likely the hard part. For that, Fred's advice is spot on: think about how to get at the information for each of the file formats you need to deal with, and only then consider how to represent it in memory and how to write it to an XML file.

[James Ogar]

please guys, i have made progress by using 7-zip c# open source code to extract the files from the archives. For now the only thing i need is some Java Codes to convert the various files format to XML UTF-8. Please i need your help. Thanks

[Ulf Dittmer]

Which file formats have you yet to tackle? The API will likely be different for each format. Or you can give Apache Tika a try; it can extract text from a wide range of formats.

Creating XML can be done using any number of APIs, or just writing it directly to a text file.

I am converting the following file formats .add, .dat, .txt

[Ulf Dittmer]

.add and .dat are not standard file formats; you'll have to figure out on your own how to extract the data from them. .txt is easy to read, but there, too, you have to figure out its format, meaning where in the text file is stored which of the various pieces of data you intend to fill the XML with.

[fred rosenberger]

the extension on a file name is really meaningless. It is a HINT - nothing more - to the computer on what program should be used to open the file. But you can take any file on your computer and changes the file extension. This will most likely cause your computer to try to open a file with the wrong program - so a file with text in it will be opened by (say) iTunes, which will then complain it can't understand the content of the file.

So simply saying "i have a .dat file" tells us nothing. If that's all the info you have, you are in trouble. You will need to analyze the data in the file by opening it with something - possible a hex reader if the info is binary, and then pray you can make sense of it.

Well that seems like an odd choice if this is supposed to be a Java application.

For now the only thing i need is some Java Codes to convert the various files format to XML UTF-8.

No you don't. And even if you did; that's not what we do here. We are NotACodeMill (←click).

It sounds to me like you've been given an awful lot of instructions about HOW to do this, when what you really need to do is understand WHAT needs to be done.

My advice:
1. Follow Fred's advice.
2. Forget all about folders and compression and patents and archiving and concentrate on the problem:
How do I convert [some] file to XML?

Pick ONE file format and get some sample files, and make sure that you can convert uncompressed versions of that format to XML, file by file - ie, write a program or method or class that converts ONE file at a time.

Once (and only once) you're satisfied that you can convert ANY file of that format, pick another format and do the same for that. In the process, you'll probably discover that there are several things that you're repeating, so refactor them into common methods (or possibly, a common class).
And when you've done that, repeat the process with a 3rd format...

Finally, once you have all your converters written and working, THEN worry about compressing/uncompressing your input and output and putting it in the right folders.

There really is no "magic bullet" to stuff like this. You need to break down the problem and understand it.
