I need to extract information from an unstructured web page in Android. The information I want is embedded in a table that doesn\'t have an id.

    One way of doing this is to put the html into a String and then manually search and parse through the String. If you know that the tags will come in a specific order then you should be able to crawl through it and find the data. This however is kinda sloppy, so its a question of do you want it to work now? or work well?
    


    int position = (String)html.indexOf("
         


        
      
      
      
");  //html being the String holding the html code
String field = html.substring(html.indexOf("",html.indexOf("",position)));

like i said... really sloppy. But if you're only doing this once and you need it to work, this just might do the trick.
