Thanks Tilman for all your great and fast work.
Unfortunately I can't share the pdf publicly, it's copyrighted.
My code for extracting the text is (simplified):
public static void main(String[] args) throws IOException {
PDDocument doc = null;
boolean hasOutputPath = false;
if (args.length != 1 && args.length != 2) {
usage();
System.exit(0);
}
if (args.length == 2) {
hasOutputPath = true;
}
try {
doc = PDDocument.load(args[0]);
if (doc.isEncrypted())
{
StandardDecryptionMaterial sdm = new
StandardDecryptionMaterial("");
doc.openProtection(sdm);
}
}
catch (IOException e) {
System.err.println("Error loading PDF file");
e.printStackTrace();
System.exit(0);
}
catch (BadSecurityHandlerException e) {
e.printStackTrace();
System.exit(0);
}
catch (CryptographyException e) {
e.printStackTrace();
System.exit(0);
}
TextParser parser = new TextParser(hasOutputPath? args[1]:
args[0]);//A class of mine to parse the text received
PDDocumentOutline outlineRoot =
doc.getDocumentCatalog().getDocumentOutline();
PDOutlineItem parentItem = outlineRoot.getFirstChild();
String parentTitleName;
String currentChildTitleName;
String nextChildTitleName;
PDFTextStripperExt stripper = new PDFTextStripperExt();
boolean childrenWereParsed = false;
while (parentItem != null) {
parentTitleName = parentItem.getTitle();
if (Pattern.matches(".*Commands", parentTitleName)) {
PDOutlineItem item = parentItem.getFirstChild();
while (item != null) {
currentChildTitleName = item.getTitle();
stripper.setStartBookmark(item);
if ((item = item.getNextSibling()) == null) {
nextChildTitleName = (parentItem =
parentItem.getNextSibling()).getTitle();/*need to check null on next parent
item but in this pdf case it won't happen*/
stripper.setEndBookmark(parentItem);
}
else {
nextChildTitleName = item.getTitle();
stripper.setEndBookmark(item);
}
parser.parseText(stripper.getTextBySpecification(doc),
currentChildTitleName, nextChildTitleName);
docCount++;
}
childrenWereParsed = true;
}
if (!childrenWereParsed) {
parentItem = parentItem.getNextSibling();
}
}
}
(there might be some syntax errors since I simplified the code, but this is
the main concept)
The code which I was talking about with the *namesDict =
doc**.getDocumentCatalog().getNames()
*returns *null *is part of the pdfbox code in the *findDestinationPage *method
in the section of the *if( rawDest instanceof PDNamedDestination )* in the
*PDOutlineItem* class.
It sems that there is an anomaly in this spacific pdf. Ill try to load the
pdf with *loadNonSeq(file,null) *and see what's the difference.
Noam
