Have you tried doing this with Insert From URL? (FIlemaker 12)
if you are using an older version of FIleMaker, you can also use a web viewer with GetLayoutObjectAttribute to "scrape" the data from the web viewer to get this data entered into fields in your database. Note: this does NOT use a web viewer to display the info, it only uses the viewer as a way to acquire the data from the web site.
Didn't know about that new Script Step. I see that it brings in the raw xml data, so I will need to parse it out. I will give that a shot though. Thank you
