Well, well, criticize, I'm new to programming. Tell me how to make a multipage PDF, there are solutions in Google, for a specific text, and for me it is parsed from XML.

The table is continuous, not divided into pages. Help please, I can not solve this problem.

    1- it doesn't matter what the input is xml. Examples of creating a multi-page pdf with reportlab will not stop working wherever the input text appears 2 - you don't need all the code that you have to put in the question. Create a minimal example that demonstrates the problem of a minimal reproducible example Explicitly describe what you wanted to get and what exactly is happening instead. Explicitly minimal input example specify. - jfs
  • This is part of the code. I would like to understand how to divide the table into several pages. There was an idea to attach to _len and the number of lines, on the first page, let's say 20, on the other 60. But the lines can have different heights (depending on the data). I think this is a wry decision. The second option is to specify the allowable area to fill the page, in particular the bottom. How can I not understand this, or am I going in the wrong direction? - Dmitriy From
  • I would like to get a table that automatically went to another page and had a subtitle. - Dmitriy From
