I would like to delete all pages that contain a certain phrase utilizing a Javascript Action

[hometrader1]

I generate several large PDF files and would like to delete any page within these files that contain a certain phrase and then save the new file.

With JavaScript you can look for words in the document and you can delete pages.

I've been playing around with a couple different variations of code, but nothing has worked.  I've used the following to pull the pages with a certain word, but I think it would be better to delete pages with a phrase.  Any suggestion?

var pageArray = [];

var stringToSearchFor = "Weight";

for (var p = 0; p < this.numPages; p++) {

// iterate over all words

for (var n = 0; n < this.getPageNumWords(p); n++) {

if (this.getPageNthWord(p, n) == stringToSearchFor) {

pageArray.push(p);

break;

}

}

}

if (pageArray.length > 0) {

// extract all pages that contain the string into a new document

var d = app.newDoc(); // this will add a blank page - we need to remove that once we are done

for (var n = 0; n < pageArray.length; n++) {

d.insertPages( {

nPage: d.numPages-1,

cPath: this.path,

nStart: pageArray,

nEnd: pageArray,

} );

}

  // remove the first page

  d.deletePages(0);

}

When you're deleting pages, it's far easier to work backwards. Iterate through the pages from the back to the front and just delete the page that contains the word or phrase you're looking for.

I would love to accomplish that, but can't get the code correct.  Any suggestions?

You can delete pages and save the document with a new name.

Code suggestions?

Look for saveAs in the Acrobat JavaScript Reference.

This code extracts the pages that contain the word "losses" and then prompts to save those pages.  I'm looking to save all the pages that don't contain that word.  Any ideas?

var pageArray = [];

var stringToSearchFor = "losses";

for (var p = 0; p < this.numPages; p++) {

// iterate over all words

for (var n = 0; n < this.getPageNumWords(p); n++) {

if (this.getPageNthWord(p, n) == stringToSearchFor) {

1. pageArray.push(p);

break;

}

}

}

if (pageArray.length > 0) {

// extract all pages that contain the string into a new document

var d = app.newDoc(); // this will add a blank page - we need to remove that once we are done

for (var n = 0; n < pageArray.length; n++) {

1. d.insertPages( {

nPage: d.numPages-1,

cPath: this.path,

nStart: pageArray,

nEnd: pageArray,

} );

}

  // remove the first page

  d.deletePages(0);

}

Delete the pages which are stored in the pageArray.

Exactly how would I do that? 

[Bernd Alheit]

Use the method deletePages. Make sure that you go from highest to lowest page number.
