Extract text using pdfbox
hi
Actually i search various site and read different forum but not able to
find a way to read a single line from specific page number and also want to
extract its property of that line.
Is there is any way to read pdf by using readLine() method of bufferReader
or some other way
Please suggest me

hello Vladimir
sir read the code but unfortunately i am unable to understand the code
PDFStreamParser parser = new PDFStreamParser(contents.getStream() );
parser.parse();
List tokens = parser.getTokens();
for( int j=0; j<tokens.size(); j++ )
{
Object next = tokens.get( j );
if( next instanceof PDFOperator )
{
PDFOperator op = (PDFOperator)next;
//Tj and TJ are the two operators that display
//strings in a PDF
if( op.getOperation().equals( "Tj" ) )
{
//Tj takes one operator and that is the string
//to display so lets update that operator
COSString previous = (COSString)tokens.get( j-1 );
String string = previous.getString();
string = string.replaceFirst( strToFind, message );
previous.reset();
previous.append( string.getBytes("ISO-8859-1") );
}
else if( op.getOperation().equals( "TJ" ) )
{
COSArray previous = (COSArray)tokens.get( j-1 );
for( int k=0; k<previous.size(); k++ )
{
Object arrElement = previous.getObject( k );
if( arrElement instanceof COSString )
{
COSString cosString = (COSString)arrElement;
String string = cosString.getString();
string = string.replaceFirst(
strToFind, message );
cosString.reset();
cosString.append(
string.getBytes("ISO-8859-1") );
}
}
}

?

Hi Rahul,
PDF is a binary format and readable text which is visible in a single line could be organized in various pieces within a PDF. I think the easiest option for you might be to use the ExtractText command line tool as a start and review the result http://pdfbox.apache.org/commandlineutilities/ExtractText.html. Use the sort option to arrange the text sorted by it's position.
