如何使用jsoup检查网页中是否存在字符串？

Question

protected Void doInBackground(Void... params) {
    try {
        doc = Jsoup.connect(url).get();
        linksOnPage = doc.select("h2.filmibeat-myshow-movie > a[href][title]");
    }catch (Exception e){
        e.printStackTrace();
    }
    return null;
}

    @Override
protected void onPostExecute(Void aVoid) {
    //Log.e("Value", txt);
    for(Element link : linksOnPage) {
        //Log.e("fsdsd", link.attr("title"));
        if (link.attr("title").contains(txt)) { // The search I tried
            final Toast toast = Toast.makeText(MainActivity.this,"YO",Toast.LENGTH_SHORT);
            toast.show();
            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    toast.cancel();
                }
            },1000);

        }

    }
}

包含（txt）方法并不总是适用于所有输入，我总是得到一个＆＃34; NO＆＃34;敬酒。我想检查网页中是否存在输入txt。请帮助！
