Conditional Section Rendering

[sammyhajomar]

I'm working with 100-150 page PDFs that have multiple sections (75-100) that can be isolated by a regex pattern (i.e. Section 1, Section 2, etc...). Is there a way I can just render a single one of those sections of the PDF instead of the entire PDF? A section could start and end in the same page or span multiple pages. Sections don't necessarily start at the beginning of the page.

What I have tried is extracting the entire text from the PDF and then cut it up into sections and displaying it for the user however, the text has varied formatting (line position, bolding, underline, strikthrough, etc...) and when I extract the text all of that gets stripped away.
