Hi netsonicyxf,

If the document is not secured, all link information can be exported as an XFDF file using "Export Links..." in the Options menu of the Links pane. A Feature Request has already been issued, but currently the only way is to process the XFDF file in the user's preferred way.

Hi rakunavi,

Thank you. But How do I get all these links (as text)?

Best regards

Hello netsonicyxf,

You can not currently do that. Once the feature request from the other topic is done, and the feature added to the Editor you would be able to export to other file formats than .fdf /.xfdf.

Kind regards,
Stefan

Hi netsonicyxf,

With all due respect, I have no way to know what you don't understand, so it's difficult for me to comment. Even if it were clear, it might be difficult in this forum to give you hands-on advice on how to operate after outputting with XFDF, since the forum rules prohibit comments that are not directly related to Tracker-Software's products.

If you don't know how to output XFDF, you will have to look at the PDF-XChange Editor manual.

If you don't know how to handle text files, you will have to learn the basics of Windows.

If you don't know how to use regular expressions, you can learn from the following excellent site. The results are displayed in real time, allowing you to efficiently deepen your understanding of regular expressions.

Of course, you should also read the basic documents such as those cited in the PDF-XChange Editor Help. There are many excellent resources on the web about regular expressions.

• https://en.wikipedia.org/wiki/Regular_expression
• https://cplusplus.com/reference/regex/ECMAScript/

Based on the format of URLs included in XFDF, the following pattern should be sufficient.

Code: Select all

https?:[^"]+

The PDF-XChange Editor itself has some settings where regular expressions can be used, such as replacing bookmark titles, so it is good to know about them.

Normally, it would be necessary to install a grep tool in addition to the above, but even if you don't go that far, the above site (https://regex101.com/) has a function to copy text matched with regular expressions, so that may be all you need to do.

Hoping that the above information will be of some help to you.

Best regards,
