EPI Separation

For EPI (Embedded Page Information) Separation, a Data Extractor is used to find page numbers from the text on a page (i.e. "Page 1 of 10"). This is set on the "Value Extractor" property. The extractor must also define two groups "PageNo" and "PageCount" in its regular expression pattern (The pattern "Page (?<PageNo>\d+) of (?<PageCount>\d+)" would group the "1" and "10" of our earlier example properly). If the value of PageNo is 1, a new folder is created. As long as each subsequent page's PageNo value follows in sequence, they are included in the folder. If the page is out of sequence (or the extractor fails to produce a result), it is left as a loose page.
