Your question sounds like "I have no money in my wallet; how can I fetch the zero dollar notes from my wallet?"
In a PDF, all text is added at absolute positions. For instance: one word is added at position x = 36, y = 806; another word is added on position x = 300, y = 806. Some other text is added at position x = 36, y = 790; x = 36, y = 774; x = 36; 742;... Where are the spaces? There are none! But by doing the math, you can see that there's a gap between the text that starts at position x = 36 and the one that starts at position x = 300. Also, you see a pattern in the y positions: 806 - 16 = 790; 790 - 16 = 774; 774 - 16 = 758; 758 - 16 = 742; ... This looks like a line was skipped at position 758. However, as explained multiple times, the concept of a line doesn't exist in PDF.
