You may be able to do this using the following article from File Exchange by Dimitri Shvorob http://www.mathworks.com/matlabcentral/fileexchange/19798-extract-text-from-a-pdf-document
The following are the steps mentioned in the submission.
The following is a modified version of the code from the submission containing just the parts relevant for you. Please change the file paths as required and download the jars from the link above.
clear java
javaaddpath('L:\NewJars\PDFBox-0.7.3\lib\PDFBox-0.7.3.jar')
pdfdoc = org.pdfbox.pdmodel.PDDocument;
reader = org.pdfbox.util.PDFTextStripper;
pdfdoc = pdfdoc.load('L:\NewJars\Sample 1.pdf');
pdfdoc.isEncrypted
%%text, with planty of padding
pdfstr = reader.getText(pdfdoc) %#ok
class(pdfstr)
pdfstr = char(pdfstr) %#ok
class(pdfstr)
%%text 'unpadded'
pdfstr = deblank(pdfstr) %#ok
%%will get an error here..
pdfdoc = pdfdoc.load('L:\NewJars\Sample 1.pdf');
pdfdoc.isEncrypted
pdfstr = reader.getText(pdfdoc) %#ok
%%but press forward..
pdfdoc.getDocument().close;
The variable “pdfstr” stores the text in the PDF document as a “java.lang.string. “ object. You can search for words in this string using the below code. You can check for other functionality available fo string using the “tab” auto completion.
>> pdfstr.indexOf('MathWorks')
ans =
11
You can also convert to a char array and use as needed
>> result = pdfstr.toCharArray();
