Comparing the contents of two files

I have two ASCII files.
The files contain data from two identical tables in "|" delimited form.
I need to compare the two files and determine if there is any difference between the two files.
Any inputs will be appreciated.
Thank you.

In Windows I've found a piece of shareware called WinMerge to be very useful. Try using Google to find it.

How can i compare the contents of two folders ?

how can i compare the contents of two folders and find out which files are in one but not in the other?? Knowing how to do this would be the best thing ever, especially when dealing with a large number of files. Often, for instance, I'm dealing with a large number of images, processing them, and saving the retouched ones to a new folder, and need to check that they are all there. If there are say three files missing in the second folder (out of say a hundred in total) being able to automate the process of elimination would be very useful. Please help!!!

I really wish I knew the answer to this. I work between two macs, a G5 and MacBook Pro when I'm on the go. Each time I move from one to the other I have to copy all my files to the computer I'm going to work on, so I end up with the same files being duplicated. It's not a problem if it's not much data but in my case the it can be to 30GB, mostly graphics files, photoshop, motion, final cut pro, etc.
There's has got to be a way automator can make a comparison between two folders to sort out what's changed and what's remained the same. It would be nice also if this feature could be done globally on the hard disk using spotlight's technology to stop files being duplicated in places you didn't even know about and taking up valuable disk space. I'm not sure how this could be done.
Any bright ideas Apple?

How to compare the contents of two XML documents

Hi all,
I was trying to compare the contents of two xml documents, they are both validate for the same XML Schema. i was using the xmlunit to do this. but some how it doesn't work like what i have expected. for example:
1.xml : <test><item>2</item><item>1</item></test>
2.xml: <test><item>3</item><item>2</item><item>1</item></test>
the result from XMLUnit is this two xmls are different, but it compares <item>2</item> with <item>3</item>, which i cannot find out where the real diiffs are.
does anybody know how i can do this correct?
best regards,
tina

I faced a similar problem in one of my projects and hence wrote my own comparator. Most comparators like ExamXML etc show XML as different if the nodes under a parent node occur in different seqeunce or a set of repeated nodes occur in different sequence. The comparator that I wrote gives you the flexibility to configure how to identify a node from a set of repeated nodes and is able to compare them successfully if they occur in any order. You can view the sample output at http://geocities.com/dheerendra_itbhu/TipsFromDheeru.html
and contact me in case you need the source code.

Hi Awen,
This is quite easy to do, you can merely use the "read from spreadsheet file" function to get a 2D array (2 columns and n rows) and then use the index array function to get whatever row/colums you want..
Hope the attached VI helps you

Is there a way to compare the contents of a library by comparing itl files or some other files?

Is there a way to compare the contents of a library by comparing itl files or some other files?
I need to compare the contents of my current library to one that existed 2 months ago but ALL I have is the itl file from 2 months ago. Can this be done?

You are correct, many people have noticed over the years that Sound Check does not work as advertised.
A more effective approach is to treat the files with a 3rd party volume normalization program. Although I have not personally used it, many users on this Forum have reported good results from an inexpensive program called iVolume.

How to read the contents of XML file from my java code

All,
I created an rtf report for one of my EBS reports. Now I want to email this report to several people. Using Tim's blog I implemented the email part. I am sending emails to myself based on the USERID logic.
However I want to email to different people other then me. My email addresses are in the XML file.
From the java program which sends the email, how can I read the fields from XML file. If any one has done this, Please point me to the right examples.
Please let me know if there are any exmaples/BLOG's which explain how to do this(basically read the contents of XML file in the Java program).
Thank You,
Padma

Ike,
Do you have a sample. I am searched so much in this forum for samples. I looked on SAX Parser. I did not find any samples.
Please help me.
Thank you for your posting.

How To Fetch the Content of a File from Client's PC?

In my JSP I have this:
<input type="file" name="filename">for visitors of the web page to browse their PCs' directories to select a file to upload (when the Submit button is clicked).
What appears in the text field will be a file name. How do I get both the file name and the content of that file to be saved in the database?

From http://www.htmlhelp.com/reference/html40/forms/input.html:
A form that includes a file INPUT must specify METHOD=post and ENCTYPE="multipart/form-data" in the <FORM> tag. CGI libraries such as CGI.pm allow simple handling of such forms.
Form-based file upload is unsupported by many currently deployed browsers. Authors should provide alternative methods of input where possible.
The following example allows the user to upload an HTML document for validation:
<FORM METHOD=post ACTION="/cgi-bin/validate.cgi" ENCTYPE="multipart/form-data">
<P>Select an HTML document to upload and validate. If your browser does not support form-based file upload, use one of our alternate methods of validation.</P>
<P><INPUT TYPE=file NAME="html_file" ACCEPT="text/html"></P>
<P><INPUT TYPE=submit VALUE="Validate it!"></P>
</FORM>
Your servlet would then have to process whatever data is put into that parameter. You can look at O'Reilly's servlet utilities, or one of the other other links here:

How to store the contents of a file

Hi,
I'm using forms6i and database 10g.
Through forms if a user selects a filename , and clicks a button or something,
the contents of the file should be saved in the database.
The file can be of any type, like .doc,.pdf,.xml,.html etc...
and the contents filed will be of type varchar
Please help me do this..
Thanks

Do you really want to save the "Content" of a file or the file itself? If you try to save the contents of a .doc or .pdf in a column with a VARCHAR2 datatype, you are going to corrupt the contents of the file since these file types have binary data in them as well as text. I think you would have greater success storing the actual file in a BLOB column.
Here are a few Oracle Support documents that discuss how to store and retrieve files stored as BLOBs in the database.
Doc ID: 168277.1 - How to Upload Binary Documents Back to Database BLOB Column from Forms
Doc ID: 330146.1 - How to write BLOBs Stored Inside the Database Out to Files.
Hope this helps,

How to save the contents of a file(not a text file)

Hi all, I want to save the contents of a file(,png file, not a text file) as a field in a class. Shall I have it as a string or byte array or something?
I have tried saving a file in a string but there were some problems with loading the file from a different platform. Following is my code.
        String string;
        try {
            StringBuffer sb = new StringBuffer(1024);
            char[] characterArray = new char[1024];
            BufferedReader br = new BufferedReader(new FileReader(file));
            while(br.read(characterArray) != -1){
                sb.append(String.valueOf(characterArray));
            br.close();
            string= sb.toString();
        } catch (IOException ex) {
            ex.printStackTrace();
        }and I use the following code to recover the string back to a stream, and save that stream back to a time later.
    ByteArrayInputStream bais = new ByteArrayInputStream(map.getBytes());I realized that because this file is not a text file, the string could cause some problems. But anyone could tell me if I should use a byte array or someting? and how?
Any help would be appreciated!
Cheers,
Jing

You should use a byte array, and the binary streams (InputStream a& OutputStream). Never use Strings and Reader/Writer if you have binary data.

Reading the contents of a File without using the fileref

Hi ,
I was trying to read the contents of a file (not upload
basically) without using the fileref.upload or any servlets.
I wanted to give this file as input(dataprovider) to a
datagrid from the local instead of uploading it to the server and
fetching the contents from there.
I will explain the scenerio here:
1.I have a text field. (Here I am providing the path of the
file located).
2.There is a Submit button .(On click should be able to take
the specified file as input and read the contents of the file)
which should be able to read the contents of the file path
specified in step1.
I want to basically provide the contents of this xml file as
data provider to a datagrid.
can anyone please provide some help on this issue.
thanks

You cannot access the local file system in Flex. You need to
upload the file to the server, and then populate the file from that
uploaded file. Unless of course you are using AIR, then this is
doable.

please tell me how and where to use it..How? -- See the IO Tutorials on Sun for the FileReader (and I assume you know how to call setText and append in the JTextArea).
Where? -- In the actionPerformed method (better would be a separate thread that is triggered through the actionPerformed method, but that is probably beyond you at the moment), of course.
Give it a try.

Is it possible to display the content of a file in flex as it is written. E.G. a log file

I have flex app sitting on a Linux server.
I want to be able to spool the content of a file on the same server as the flex app to the users screen using say a textarea or similar.
The file is some type of log so its going to constantly have lines added. Is there a way to do this ? I am guessing I need to constantly refresh the flex app with the file content.

Yes you can. Small example for you:
