Does IBR support to extract text from office files

hi Experts,
Can we use IBR to extract word/excel/ppt content to a text file? where is doc for this function?
Best regards

Hi ,
Extraction of text based on some rules ?Is that what you are looking for ? Is it for searching on those specific set of texts from the file ? If yes , then you have Oracle Text search feature which would do that .
If it is to populate some metadata with those extracted texts , then it would be Content Categorizer component . For details on this component and it's functionality please go through the following documentation : http://docs.oracle.com/cd/E14571_01/doc.1111/e10978/c11_content_categorizer.htm#sthref1210
In either cases , IBR is not the actual engine which would do this . It is solely used for document conversion . \
Hope this helps .
Thanks,
Srinath

Extracting text from PDF files produced by Oracle reports

Hi,
I am currently using Report Builder 9.0.4.0.21 to produce reports in PDF format.
The pdf reports were displayed to screen and printed to printer correctly.
However, doing a copy-and-paste from the pdf report to a text editor produces
garbage characters. Also, I failed to extract the text using any of available adobe
plug-ins. I know that the PDF report is using font subseting with custom
encoding.I have already read the pdf reference manual and it seems that
the PDF report is missing the mapping tables to convert the custom encoding
used in the report back to ansi or unicode.
Is there a solution to this problem?
Are there any environment variables or settings that I am missing?
Your help is really appreciated.

Hello,
Your problem may be related to a limitation in the PDF generated with Reports 9.0.2 / 9.0.4 when using Subsetting :
Font Subsetting Creates PDF Output not Searchable with Acrobat Reader (Doc ID 311345.1)
This limitation no more exists in Reports 10.1.2 / 11.1

Extracting text from a file name on export / import (Regular Expressions??)

I’m not even sure if the publishing service, File Naming, in Lightroom supports Regular Expressions or not?? Basically I’m trying to extract the left portion of the file name ie: everything before the underscore “_”. When I import a file I rename the file to reflect the current Image sequence number and then append the date the photo was taken; a typical file is as follows “05625_2008-01-05.dng” on export I would like the new name to be only the sequence number in this case “05625.jpg”. Ideally I would then like to append the folder name that contains the file… “05625 - FolderName.jpg.
I don’t want to go down the road of figuring out the correct syntax if regular expressions aren’t supported. Thanks in advance - CES

Is the imported sequence number captured in meta data somewhere or is their somewhere that all of the available fields and there reference names can be found???
Unfortunately not anywhere available to the user (but it's still stored in at least some filed I know off).
By the way, why did you choose to put the suffix at the beginning of the name (1234_2010-08-13.jpg)? The common practice is to leave the suffix at the end. That will ensure the filenames will sort in chronological order by filename and you could have easily used the suffix when exporting files. You wouldn't have this problem now.

How to extract text from a PDF file?

Hello Suners,
i need to know how to extract text from a pdf file?
does anyone know what is the character encoding in pdf file, when i use an input stream to read the file it gives encrypted characters not the original text in the file.
is there any procedures i should do while reading a pdf file,
File f=new File("D:/File.pdf");
               FileReader fr=new FileReader(f);
               BufferedReader br=new BufferedReader(fr);
               String s=br.readLine();any help will be deeply appreciated.

First, you set i once, and then loop without ever changing it. So your loop body will execute either 0 times or infinitely many times, writing the same byte every time. Actually, maybe it'll execute once and then throw an ArrayIndexOutOfBoundsException. That's basic java looping, and you're going to need a firm grip on that before you try to do anything as advanced as PDF reading. the case.oops you are absolutely right that was a silly mistake to forget that,
Second, what do the docs for getPageContent say? Do they say that it simply gives you the text on the page as if the thing were a simple text doc? I'd be surprised if that's the case.getPageContent return array of bytes so the question will be:
how to get text from this array? i was thinking of :
    private void jButton1_actionPerformed(ActionEvent e) {
        PdfReader read;
        StringBuffer buff=new StringBuffer();
        try {
            read = new PdfReader("d:/getjobid2727.pdf");
            read.getMetaData();
            byte[] data=read.getPageContent(1);
            int i=0;
            while(i>-1){
                buff.append(data);
i++;
String str=buff.toString();
FileOutputStream fos = new FileOutputStream("D:/test.txt");
Writer out = new OutputStreamWriter(fos, "UTF8");
out.write(str);
out.close();
read.close();
} catch (Exception f) {
f.printStackTrace();
"D:/test.txt" hasn't been created!! when i ran the program,
is my steps right?

Javascript in .PDF's - Extracting text from .doc or .txt

Hello All,
I am very new to javascript in .pdfs -- but I seem to find my around doing misc. work with forms. What I need:
I need a Form with a Submit button that locates and extracts the text from a file and places it into another field.
Example:
on Server:
one.txt or one.doc
two.txt or two.doc,
...etc
You type one in the form and submit -- it pulls all of the txt from one.txt off the server and places it into a field.
Also if there is anyway to do this with tables to avoid multiple files that would be even better.
I know I am a newbie, but this would be a game-changer for what I do.
Thank you.

Thanks for the advice
It is accessing a shared file server (among employees) and it is to be a .pdf used in Adobe Acrobat Professional
Basically I want it to be a form that pulls txt based on what was in the typed box or drop-down menu from a .txt or .doc

The HTML files are get from ACM Digital Library. http://portal.acm.org/dl.cfm
The HTML page is about the information of a paper. I only want to get the text of "Title" "Abstract" "Classification" "Keywords"
The Problem is that I can't find any patten to parser the html files"
EX: I need to get the Classification = "Theory of Computation","ANALYSIS OF ALGORITHMS AND PROBLEM COMPLEXITY","Numerical Algorithms and Problem","Mathematics of Computing","NUMERICAL ANALYSIS"......etc .
The section code about "Classification" is below.
Please give any idea to do this, or how to find patten to extract text from this.

One approach is to download Htmlparser from sourceforge
http://htmlparser.sourceforge.net/ and write the rules to match title, abstract etc.
Another approach is to write your own parser that extract only title, abstract etc.
1. tokenize the html file. --> convert html into tokens (tag and value)
2. write a simple parser to extract certain information
find out about the pattern of text you want to extract. For instance "<class "abstract">.
then writing a rule for extracting abstract such as
if (tag is abstract ) then extract abstract text
apply the same concept for other tags
Attached is the sample parser that was used to extract title and abstract from acm html files. Please modify to include keyword and other fields.
good luck

Extract Text from pdf using C#

Hi,
We are Solution developer using Acrobat,as we have reuirement of extracting text from pdf using C# we have downloaded adobe sdk and installed. We have found only four exmaples in C# and those are used only for viewing pdf in windows application. Can you please guide us how to extract text from pdf using SDK in C#.
Thanks you for your help.
Regards
kiranmai

Okay so I went ahead and actually added the text extraction functionality to my own C# application, since this was a requested feature by the client anyhow, which originally we were told to bypass if it wasn't "cut and dry", but it wasn't bad so I went ahead and gave the client the text extraction that they wanted. Decided I'd post the source code here for you. This returns the text from the entire document as a string.
 private static string GetText(AcroPDDoc pdDoc)
 AcroPDPage page;
 int pages = pdDoc.GetNumPages();
 string pageText = "";
 for (int i = 0; i < pages; i++)
 page = (AcroPDPage)pdDoc.AcquirePage(i);
 object jso, jsNumWords, jsWord;
 List<string> words = new List<string>();
 try
 jso = pdDoc.GetJSObject();
 if (jso != null)
 object[] args = new object[] { i };
 jsNumWords = jso.GetType().InvokeMember("getPageNumWords", BindingFlags.InvokeMethod, null, jso, args, null);
 int numWords = Int32.Parse(jsNumWords.ToString());
 for (int j = 0; j <= numWords; j++)
 object[] argsj = new object[] { i, j, false };
 jsWord = jso.GetType().InvokeMember("getPageNthWord", BindingFlags.InvokeMethod, null, jso, argsj, null);
 words.Add((string)jsWord);
 foreach (string word in words)
 pageText += word;
 catch
 return pageText;

Extract text from pdf

Hi, is it possible to extract text from a pdf file using the command line to get an output like you would get by using the File menu and then 'Save as text..."?
I also noticed that in the installation folder there is a small executable called AcroTextExtractor which sounds interesting, but I was unable to figure out how to use it.

what's wrong with using automator for this? this certainly seems the easiest. I'm not aware of any built in apple script commands that will do this. But You should also ask on the Apple script forum under Mac OS Technologies.

Applescript or workflow to extract text from PDF and rename PDF with the results

Hi Everyone,
I get supplied hundreds of PDFs which each contain a stock code, but the PDFs themselves are not named consistantly, or they are supplied as multi-page PDFs.
What I need to do is name each PDF with the code which is in the text on the PDF.
It would work like this in an ideal world:
1. Split PDF into single pages
2. Extract text from PDF
3. Rename PDF using the extracted text
I'm struggling with part 3!
I can get a textfile with just the code (using a call to BBEDIT I'm extracting the code)
I did think about using a variable for the name, but the rename functions doesn't let me use variables.

Hello
You may also try the following applescript script, which is a wrapper of rubycocoa script. It will ask you choose source pdf files and destination directory. Then it will scan text of each page of pdf files for the predefined pattern and save the page as new pdf file with the name as extracted by the pattern in the destination directory. Those pages which do not contain string matching the pattern are ignored. (Ignored pages, if any, are reported in the result of script.)
Currently the regex pattern is set to:
/HB-.._[0-9]{6}/
which means HB- followed by two characters and _ and 6 digits.
Minimally tested under 10.6.8.
Hope this may help,

Why does my iphone send all text from only one of my contacts to my email?

Why does my iphone send all text from only one of my contacts to my email? I'm curious to know if anyone else has had this issue with the Iphone 5s...

imessage has a new setting that shows all emails associated with your apple id. There are two sections, send and receive. Since you are using the same apple id, Im sure if you adjust one of those settings to your mobile number instead of your appleid, it wont send double.
You might also have to adjust your wifes settings too, so those emails dont overlap
