extract math texts and equations from pdf

hi guys, is there any way to copy and extract a mathematics text from a selectable document?

You can extract a page text using the following code: (check CommonUtil.getPageText()) [strike]But there is no API to detect whether the text is a mathematical equation or not.[/strike]

PDF doesn't specify a way to encode or represent maths inside documents so there's no way to detect maths formulas and even less to copy properly formatted text in a reliable way.

I suggest you look at the video at below link:
