android: parse html from page
i would like to parse out some text from a page.
Is there an easy way to save the product info in to a string for example? Example url: http://upcdata.info/upc/73108开发者_开发百科70008741
Thanks
Jsoup is excellent at parsing simple HTML from Android applications:
http://jsoup.org/
To get the page, just do this:
URL url = new URL("http://upcdata.info/upc/7310870008741");
Document document = Jsoup.parse(url, 5000);
Then you can parse out whatever you need from the Document. Check out this link for a brief description of how to extract parts of the page:
http://jsoup.org/cookbook/extracting-data/dom-navigation
If you want to read from a URL into a String:
StringBuffer myString = new StringBuffer();
try {
String thisLine;
URL u = new URL("http://www.google.com");
DataInputStream theHTML = new DataInputStream(u.openStream());
while ((thisLine = theHTML.readLine()) != null) {
myString.append(thisLine);
}
} catch (MalformedURLException e) {
} catch (IOException e) {
}
// call toString() on myString to get the contents of the file your URL is
// pointing to.
This will give you a plain old string, HTML markup and all.
String tmpHtml = "<html>a whole bunch of html stuff</html>";
String htmlTextStr = Html.fromHtml(tmpHtml).toString();
