Unable to print the Text associated with the li tag - selenium

Question

I have a Google Search bar with a drop down and the options are under a UL and the actual ones under the li. I am unable to retrieve the data field of the li, while I am able to retrieve the count. Have tried with the List elements and looping thru it ,but no luck. The drop with all the Options is Not visible.
I have to print the Titles associated with the li using Selenium Web driver.
Below is what I tried:
ul class=classname> xxx – GSA 2 days ago
wb.findElement(By.xpath("<>")).click();
List items = html_list.findElements(By.tagName("li")); System.out.println("The size of the elements is " + items.size()); for(WebElement item : items) { html_list.sendKeys( Keys.DOWN ); //simulate visual movement
wb.manage().timeouts().implicitlyWait(1000, TimeUnit.SECONDS); System.out.println(item.getText());
}

Hypohesis #1: You don't wait for the page to load after the click on line 1. The li elements are in the DOM but they are not completely loaded. You could test the hypothesis by introducing a delay between line 1 and line 2. I have code that I use to wait for page loads but the specifics depend on the JavaScript framework (e.g. jQuery, AngularJs), on the loading spinner implementation and browser readystate. My readystate logic looks like this:
/**
* Wait for browser readystate to be complete. But don't wait forever.
*
* #param webDriver
*/
public void waitForBrowserReadystateComplete(WebDriver webDriver) {
for (int a=0; a<20; a++) {
JavascriptExecutor javascriptExecutor = (JavascriptExecutor) webDriver;
if (javascriptExecutor.executeScript("return document.readyState")
.toString().equals("complete")) {
break;
}
sleepResponsibly(500);
}
}
public void sleepResponsibly(int timeMillisecond){
try{
Thread.sleep(timeMillisecond);
} catch (InterruptedException ex) {
Thread.currentThread().interrupt();
throw new RuntimeException(ex);
}
}
Hypthosis #2: The text nodes are complex. I have experienced a failure in method getText() to return text when the text nodes code complex formatting. I got around this by invoking the following instead:
public static String getTextFromElementsTextNodes(WebDriver webDriver, WebElement element) throws IllegalArgumentException {
String text = "";
if (webDriver instanceof JavascriptExecutor) {
text = (String)((JavascriptExecutor) webDriver).executeScript(
"var nodes = arguments[0].childNodes;" +
"var text = '';" +
"for (var i = 0; i < nodes.length; i++) {" +
" if (nodes[i].nodeType == Node.TEXT_NODE) {" +
" text += nodes[i].textContent;" +
" }" +
"}" +
"return text;"
, element);
} else {
throw new IllegalArgumentException("driver is not an instance of JavascriptExecutor");
}
return text;
}
A caveat is that getTextFromElementsTextNodes() may return non-ASCII charcters so I do the following:
System.out.println(getTextFromElementsTextNodes(wb,item).replaceAll("[^\\x00-\\x7F]", " "));

I could finally able to retrieve the options under the li. This is what I did and it worked
for(WebElement MyListOptions: listOfLiTags) {
String myoptions=serchOptions.getAttribute("<<The actual attribute value which is storing my options>>");
System.out.println("THE List Options are" + txt3);
}
