"Search for a phrase in multiples PDFs via a list of URLs"

carlcarl Member Posts: 30 Maven
edited June 2019 in Help

Is it possible to input a list of URLs (which contain PDFs), then search for a phrase in all the PDFs, and return a table with the URL path and the searched-for text?  I'd like to do this without downloading all the PDFs.

 

This is what I have so far, which runs, but doesn't create an attribute.

 

1 - Read Excel (with URLs)

2 - Loop Examples

2a - Extract Macro

2b - Open File

2c - Read Document

2d - Extract Information

3 - Select Attributes

    Here you go.  You needed a Documents to Data operator to change your PDF text into an ExampleSet.
