title: Parsing big XML files using SAX parser (skip some lines/tags)
body: <p>I am currently developing an app that retrieves data from the internet using SAX. I used it before for parsing simple XML files like Google Weather API. However, the websites that I am interested in take parsing to the next level. The page is huge and looks messy. I only need to retrieve some specific lines; the rest is not useful for me.<br>
  Is it possible to skip those useless lines/tags, or do I have to go step by step?</p>
