Hi,
I have a question evaluating pdf-files.

Is it possible to get a pdf-file into a Coldfusion variable to evaluate the content e.g. with a Regex, to extract some Information as a string to store this in a Database.

I have to evaluate lots of pdf-files, which have specific strings in it.
I have to find these strings and check against a database whether they are already present in the database.

I have seen, that i can evaluate the properties of the pdf-file with <cfpdf action: "read">. But I I do not understand how to get the body of the pdf-file into a variable.

Any hint is highly appreciuated!

sorry, this does not work.

With this code:

<cfpdf action = "read" source = "dok_1.pdf" name = "mypdf">
<cfdump var="#mypdf#"/>

You shouldn't expect it to work. You can't dump a binary like that.

That was just a part answer to a part question. To peek into the text of a PDF, you may use the utility Daverms recommends.

If you choose to do it yourself, use Coldfusion 8's DDX functionality. Here is an example to illustrate. The folder ddxTest contains the files myDDX.ddx, textFromPDF.cfm and myDoc.pdf, an arbitrary PDF that contains the text.

Great!
Thank you. Did it as you said. Success.
DDX is not soo complicated as it seems from the first look at it.
Nice weekend.

Maybe i do not understand the cfpdf tag the right way.
What i want is a kind of pdf-to-text conversion.
Do I have to use the processddx action? I do not think so. But there is a property DocumentText .. ?
