Xpath expression for detecting chapter marks

p3aul · 11-13-2010, 10:55 PM

Can someone create an xpath expression for me to detect chapters that are numbers and are listed on a line by them selves. It must be able to detect both single digits and double-digits. As in:

blah blah blah.

3

more blah blah blah

It's important to note that I use ebook-convert ONLY on the command line to do my conversions.

With all due respects to the GUI, I prefer the command line.
Thanks,
Paul

I have not tested it, but try

Code:

--chapter "//*[re:test(., '^[0-9]+$')]"

The "^" is for start of line, "[0-9]" is a digit, "+" is one or more instances, "$" is end of line.

Well, I just got an error and it wouldn't compile. Here is a screen shot. Maybe you can see the problem from the error msg.
Thanks,

There are two --chapter entries, the first one should be removed. The xpath part is in double quotes and it is placed after a single --chapter command line argument.

My inner geek forced me to write this: That's not compiling, that's running a program (or failing to do so

). Compiling is the act of turning human-readable program source code into machine code (as in "an executable program").

Wallcraft: Beautiful! Thank you for pointing out my error, and for providing the code.

UPDATE: Hey, I want you to know that your xpath statement works on roman numeral also! I just substituted those for a book where the chapters were all roman numbers and it worked!

Manichean: Code, script? So what's a name? just a label. BTW, I was programming in machine code when you were in diapers!
