和Adobe Reader一样，您将需要Adobe Acrobat.

As well as Adobe Reader you will need Adobe Acrobat.

使用操作向导"添加以下脚本:

Add the following script using the Action Wizard:

粘贴以下脚本，然后根据需要进行修改.请参阅//评论以获取有关自定义的帮助.

Paste in the following script and modify for your needs. See //comments for help on customisation.

/* Extract Pages into Documents by Keyword */
// Iterates over all pages and find a given string and extracts all 
// pages on which that string is found to a new file.

var pageArray = [];
var pageArrayEnd = [];

var stringToSearchFor = app.response("This Action Script splits the document by a keyword on each X number of pages, please enter the keyword:");

for (var p = 0; p < this.numPages; p++) {
    // iterate over all words
    for (var n = 0; n < this.getPageNumWords(p); n++) {
    // DEBUGGING HELP, UNCOMMENT NEXT LINE, CHANGE TO MATCH MULTIPLE WORDS OR WHAT EVER ORDER, eg if ((this.getPageNthWord(p, n) == stringToSearchFor) && (this.getPageNthWord(p, n + 1) == stringToSearchForTWO)) {..., Also add a prompt for the second search word and iterate one less for (var n = 0; n < this.getPageNumWords(p) - 1; n++) ...
    //app.alert("Word is " + this.getPageNthWord(p, n));
        if (this.getPageNthWord(p, n) == stringToSearchFor) {
            //app.alert("Found word on page " + p + " word number " + n, 3);
            if (pageArray.length > 0) {
                pageArrayEnd.push(p - 1);
            }
            pageArray.push(p);
            break;
        }
    }
}

pageArrayEnd.push(this.numPages - 1);
//app.alert("Number of sub documents " + pageArray.length, 3);
if (pageArray.length > 0) {
    // extract all pages that contain the string into a new document
    for (var n = 0; n < pageArray.length; n++) {
        var d = app.newDoc();    // this will add a blank page - we need to remove that once we are done
            //app.alert("New Doc using pages " + pageArray[n] + " to " + pageArrayEnd[n], 3);
            d.insertPages( {
                            nPage: d.numPages-1,
                            cPath: this.path,
                            nStart: pageArray[n],
                            nEnd: pageArrayEnd[n],
            } );
        // remove the first page
        d.deletePages(0);
        d.saveAs({ cPath: this.path.replace(".pdf","") + n + ".pdf" });
        d.closeDoc(true);
    }
}
