An application that will copy emails from PDF document and and webpages (php, html and xhtml)

- I need a simple desktop application (the developer can choose any language) that will extract emails from a website I specify. - The first step, I enter a URL. There must be the ability to specify multiple URLs. - The steps below is repeated for each URL. - The application will visit the URL or website and make a list of all its resources, that is, webpages (php, html, xhtml) and PDF documents. - Next, the application will extract email addresses from each resource, for example, if it is a pdf document, it will temporarily download it on my desktop, read it to extract email addresses and delete it when done. - Same the process for the other resources, that is, other pdf documents and webpages. - When completed for all the domains, the app must inform the user, e.g., by displaying an alert box. - The user can save the list of email addresses in a txt document in the following format: email1@[login to view URL] email2@[login to view URL] email3@[login to view URL] email4@[login to view URL] email5@[login to view URL] email6@[login to view URL] - If you need any information, please do not hesitate to ask me. Thank you very much.
