The result of the app will be a folder with Google Earth map overlays:
/Users/uki/Desktop/KMZ

We will use basic java networking classes:
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.net.MalformedURLException; import java.net.URL; and regular expressions:
ublic class RegExConstants { /** * @param extensions * @return * ( -- start of main grouping * [^\s]+ -- must contains one, or many strings (but not white space) * ( -- start of extension grouping * \. -- existence of a dot, eg.: .kmz * (?i) -- NOT case sensitive for the next group * (kmz|kml) -- kmz OR kml strings * )$ -- should exist on the end * ) -- end of main grouping */ public static String fileExtensionPattern(String[] extensions) { StringBuilder sb = new StringBuilder(""); if (extensions.length > 0) { int n = 0; for (String extension : extensions) { if (n > 0) { sb.append("|"); // append OR } sb.append(extension); } } String pattern = "([^\\s]+(\\.(?i)(" + sb.toString() + "))$)"; System.out.println("fileExtensionPattern: " + pattern); return pattern; } public static final String anchorTagPattern = "<a *href=\"(.+?)</a>"; public static final String urlPattern = "(https?|ftp|file)://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|]"; }
