Identify and extract or delete pages of a PDF based on a search string / text (action / javascript) - pdf

Question

Good Evening (UK)
I'm trying to filter down a 1500+ page PDF file to only the pages which include a certain text string (typically one or two words). My laptop is locked down with respect to installing more software BUT I have used action(script)s quite a bit
I get the error below when I try to install this action into Abobe Acrobat X Pro (Win 7):
screen dump of error
called "Extract Commented Pages"... supposed to be OK for X and XI this looks like what I want.....
I wondered if there was something simple causing the problem but the actionscript file is rather... busy to say the least.
I used to have an action that I think was based on a legal redaction script but it is filed somewhere!
If you have already got an action that does this or a version of the above that doesn't give the error I get (unable to import the Action.... The file is either invalid or corrupt) I will forever by indebted to your gratitude
Many thanks, have a good weekend!

Answer 1

I recently came across a script found at the following link: http://forums.adobe.com/thread/1077118
I'm having some issues getting the script to run in Acrobat, despite everything looking alright in the script itself. I'll update if I find any errors.
Here is a copy of the script:
// Set the word to search for here
var sWord = "forms";
// Source document = current document
var sd = this;
var nWords, currWord, fp, fpa = [], nd;
var fn = sd.documentFileName.replace(/\.pdf$/i, "");
// Loop through the pages
for (var i = 0; i < sd.numPages; i += 1) {
// Get the number of words on the page
nWords = sd.getPageNumWords(i);
// Loop through the words on the page
for (var j = 0; j < nWords; j += 1) {
// Get the current word
currWord = sd.getPageNthWord(i, j);
if (currWord === sWord) {
// Extract the current page to a new file
fp = fn + "_" + i + ".pdf";
fpa.push(fp);
sd.extractPages({nStart: i, nEnd: i, cPath: fp});
// Stop searching this page
break;
}
}
}
// Combine the individual pages into one PDF
if (fpa.length) {
// Open the document that's the first extracted page
nd = app.openDoc({cPath: fpa[0], oDoc: sd});
// Append any other pages that were extracted
if (fpa.length > 1) {
for (var i = 1; i < fpa.length; i += 1) {
nd.insertPages({nPage: i - 1, cPath: fpa[i], nStart: 0, nEnd: 0});
}
}
// Save to a new document and close this one
nd.saveAs({cPath: fn + "_searched.pdf"});
nd.closeDoc({bNoSave: true});
}
