Re: MSPowerPointExtractor problem
Ryan,
thanks for your reply.
I have also seen the posts from Sudhakar on this subject who seems to
be contributing a whole lot of code here - which is a great thing but
in this code the problem also persists so I think we solve this
encoding problem in your code (which is simpler - the fix could later
be integrated into Sudhakar's code if this is checked in or
whatever...).
I have tested this with a simple PPT file containing just the following
text:
Umlaut-Test
Ökologie, Mühsal, Größe, Grätsche
I get the following console output with this text:
Umlaut-Test
\326kologie, M\374hsal, Gr\374\337e, Gr\344tsche
Here is the output I get in a web browser (through a web app, view
HTML source mode):
Umlaut-Test ÷kologie, M¸hsal, Gr¸?e, Gr?tsche
German umlaute and other special characters work fine that way
whenever I extract text from Word documents or Excel spreadsheets using
POI and Ryan Ackley's TextMining framework.
just for the record: I have only tested this on my own configuration:
Mac OS X 10.3.4, Java 1.4.2_03 so I have no idea how these classes
might behave on Linux or Windows. Can anybody confirm this? I have seen
some German names on this list ;-)
Thanks for all the work you put into this.

I haven't tested the PPT extractor with any other languages. I

reading about other people having problems with different character

though.
Could you send a before and after example file here or to bugzilla?

Subject: MSPowerPointExtractor problem
Hello everybody,
When I was searching for a Java class to extract text from PowerPoint
files, I accidentally discovered Slide.
I pulled the MSPowerPointExtractor class and some other stuff it
depends on via CVS and tried it for some text extraction.
The method I used looks very similar to the provided example main
method (see below).
However. when I tried to extract text from a German PowerPoint
presentation, I had some problems with the encoding. I did not know
which encoding to use, converting the output to ISO Latin 1 with my
text editor solved only part of the problem (some German Umlaute were
displayed correctly, some were not).
Is this a known issue or am I doing something wrong? Any hints for me?
Thanks in advance.
Ralph Scheuer
BTW. I am using Mac OS X 10.3.4 with JDK 1.4.2_03, the native encoding
on this platform is MacRoman.
public static String contentStringForData(NSData data){
StringBuffer buf = new StringBuffer();
try{
ByteArrayInputStream input = data.stream();
MSPowerPointExtractor ex = new MSPowerPointExtractor(null,
null);
Reader reader = ex.extract(input);
int c;
do
{
c = reader.read();
buf.append((char)c);
}
while( c != -1 );
}catch(Exception e){
}
return buf.toString();
}

Re: MSPowerPointExtractor problem
Hm,
Basically we have concentrated on English language. So we never faced any problems. It
become a
new task for our team now :-)
Thanks to Ralph in pointing that problem.
We Will work on related and let the Jakarta team knows :-)

Hello All,
This was my first contribution
http://wiki.apache.org/jakarta-lucene-data/attachments/PowerPoint/attachments/PPT2Text.java
for
jakarta team. And it seems another expert(Ryan Rhodes- [EMAIL PROTECTED]) has already
started working on that based on my first given contribution.
That sounds great to me.
So In order to increase the development process for Powerpoint extractor, I just
wanted to
