HNR: Episode III - Revenge of the Parse

[davidsawyer]

This fixes #13

Looks like an update to Hacker News' HTML broke the app's parsing. One single addition of a <tr> was the culprit.

I'd also recommend updating http://whoisryannystrom.com/hackernews.json:

{
  "feed": {
    "titles": "//table[@id='hnmain']/tr[4]/td/table//td[@class='title'][not(@align)]/a",
    "details": "//table[@id='hnmain']/tr[4]/td/table//td[@class='subtext']",
    "score": "//span[@class='score']",
    "comment_node": "(//a)[last()]"
  },
  "comments": {
    "comments": "//table[@id='hnmain']/tr[4]/td/table[2]/tr",
    "user": "//span[@class='comhead']/a[1]",
    "text": "//span[@class='comment']/span",
    "removed": "//span[@class='comment']",
    "indent": "//img[@src='s.gif']",
    "permalink": "//span[@class='age']/a"
  },
  "page": {
    "text": "//table[@id='hnmain']/tr[4]/td/table[1]/tr[4]/td[2]"
  },
  "user": {
    "username": "//table[@id='hnmain']/tr[4]/td//table//tr[1]/td[2]/a",
    "created": "//table[@id='hnmain']/tr[4]/td//table//tr[2]/td[2]",
    "karma": "//table[@id='hnmain']/tr[4]/td//table//tr[3]/td[2]",
    "about": "//table[@id='hnmain']/tr[4]/td//table//tr[4]/td[2]",
  }
}

It looks like they've changed the number of <tr>s back to how it was before, so the problem solved itself... for now at least. We still may want to check tr[4] as a fallback if tr[3] queries return no results, though.

Let me know your thoughts.
