Greyhound Data ExtractionGreyhound Data Extraction

• Grayhound data was gathered from www.trackinfo.com. The Web site links to:– GreyMatter http://66.236.122.233:8080/tracklink/– TrackInfo http://www.trackinfo.com/index2.html

• The race and odds data was parsed into a SQL Server database; then the data was sent to the AZGreyhound system for prediction.

22

Example code public void RacePrograms() throws Exception {

... ...

String URL1 = "http://www.trackinfo.com/trakdocs/hound/";

String URL2 = "/Rpages";

... ...

OpenConnection2();

try { ... ...

TrackAbbrev = rSet.getString("TrackAbbrev");

String URL = URL1 + TrackAbbrev + URL2;

Feed = web.Scraper(URL, 1);

... ...

NumItems = web.NumItems(Feed, "~icons/html.gif");

for(int y = 1; y <= NumItems; y++) {

Feed = Feed.substring(Feed.indexOf("~icons/html.gif"));

FileName = web.ExtractText(Feed, "<A HREF=\"", "\">");

Feed = Feed.substring(Feed.indexOf("<A HREF="));

FileDate = web.ExtractText(Feed, "NOWRAP>", "</TD>");

FileContents = web.Scraper(URL + "/" + FileName, 1);

FileContents = FileContents.replaceAll("'", "-");

db.Insert2DBProgram(FileName, FileDate, FileContents); }

}

CloseConnection2();

}

catch(SQLException e) {

System.out.println(e); }

}
