If the emails were automatically downloaded as text files from your email server, you could import them into FileMaker and parse the text as needed into other fields. I don't know if that's possible or not. (and reading the email filenames from the folder into fileMaker would be an added challenge requiring a batch file, an applescript or a third party produced File Plug In.)
If you use a web viewer to access the web site and give the web viewer and object name, you can use GetLayoutObjectAttribute with the object name of the web viewer and "content" as the second parameter to extract a mass of text (HTML tags and all). Then you can "scrape" data from this text to get the data you need.
Look up this function in FileMaker help to learn more.
The web viewer idea sounds enticing, there is a caveat however: I will need to log in to the website in order to read the message. I read the docu on web viewer but it doesn't elaborate on the subject. Any pointers ?
It depends on the design of the web site. If it permits pushing data to it via the URL to be used for logging on, (I think that would be a potential security risk most sites would not allow) you might be able to do it.
mmmhhh ... not really, login data is via https.
I think it is simpler the other way around. I use a messaging third party solution to get the emails and put them in a file on my mac and then I read the filed emails ... look what I found :
and troi's plug in:
A bit pricey but maybe it can do the trick.
This seems to be even easier ... and cheaper, I would rather read the emails directly which is what I wanted in the first place: http://www.dacons.net/fmplugins/mailit5/ . I will be testing this over the coming few days.
