android+jsoup解析html,Android平台使用Jsoup解析HTML

public void onParse(View v) {

InputStream iStream;

try {

iStream = mContext.getAssets().open("index.html");

String html = getStringFromInputStream(iStream);

Document doc = Jsoup.parse(html);

Elements elms = doc.getElementsByTag("link");

Element element = elms.get(0);

String hr =  element.attr("href");

if (hr != null) {

String hrefString = "content://" + hr;

element.attributes().remove("href");

element.attributes().put("href", hrefString);

}

Log.i("JsoupTage hr = ", hr);

String contenString = doc.outerHtml();

Log.i("JsoupTage", contenString);

} catch (IOException e) {

e.printStackTrace();

} //打开文件

}

// convert InputStream to String

private static String getStringFromInputStream(InputStream is) {

BufferedReader br = null;

StringBuilder sb = new StringBuilder();

String line;

try {

br = new BufferedReader(new InputStreamReader(is));

while ((line = br.readLine()) != null) {

sb.append(line);

}

} catch (IOException e) {

e.printStackTrace();

} finally {

if (br != null) {

try {

br.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

return sb.toString();

}
