Output XMP metadata to dynamic stamps

[involve39]

Hi,

I was wondering if it's possible to grab specific fields from the XMP metadata and insert them into a dynamic stamp.

For example, I can access the "Title" field from the standard PDF metadata via JavaScript using:

Code: Select all

console.println(this.info.Title);

I can also get the whole XML blob for the XMP metadata with:

Code: Select all

console.println(this.metadata);

What I'm missing is a way to extract one or more fields from the XML string, for example:

Code: Select all

[XMP-fx]        Document Type                   : INVOICE
[XMP-fx]        Document File Name              : factur-x.xml

Does anyone have any ideas or pointers?

Thanks!

Hello, involve39

If anyone else has ideas, that would be appreciated. I have asked the dev team for input on this, but they have been quite busy of late so I cannot promise how quickly we will see a reply (and I am not an expert on JS - creating something new is not my forte)

[Edit] Quick update, I have a reply, but possibly not the one you were looking for:

we provide XML data as a string, and it up to the user how to deal with that xml data. We do not provide any XML functionality and the JS engine we use does not support the deprecated ECMA XML extension.

Kind regards,

Hi Dan,

thanks for your reply!

Indeed, it's too bad that there's no way to parse the XML.

I was also looking at Run JavaScript in PDF Tools, to see if I can use JavaScript to get the values into my stamp.
Unfortunately, that appears to be another dead end, since there doesn't seem to be a way to pass dynamic values into the Tools_DoWork() function.

In general, that looks to me like a bit of a weak spot in PDF Tools, that I keep bumping up against.
None of the various tools like Run JavaScript, Execute application or Change document properties support arbitrary variables, which is why I have to fall back on PowerShell and 3rd party PDF apps for various workflows.

Hi involve39,

Sorry that you could not get a satisfacory resolution here - let's wait to see what the development team will say.

Kind regards,
