PrettyPrint indent size is alway 2 spaces

[Rade Martinović]

I notified this using https://github.com/eerohele/exalt which in turn uses lxml. When PrettyPrinting an XML indent is always 2 spaces. Is there a way to make this configurable?

Not easily. libxml2 does the pretty printing, and it does not have an option for changing the indentation. Supporting a different "indent" (string) option would require either a) adding that option to libxml2, or b) reimplementing the entire serialiser in lxml. I'd rather not allow the latter, and the first would mean that the feature would not always be available for users.

It saddens me to see that this is not possible to resolve in lxml. To me personally indent of 2 spaces feels unnatural. Maybe I can think of a workaround in exalt project to he a the indentation according to my preference.

Thanks for the reply.

Well, you can use this if you can afford to modify the tree before serialisation:
