Dealing with <object> tags in selenium webdriver

Many web pages uses <object> tags for embedded object within an HTML document. This element is mainly used to embed SVG elements, multimedia, Java applets, Flash etc.
Many web pages also use the <object> tag to embed another webpage or frames into the HTML document.

Though <object> tags looks slimilar to <iframe>, it won't work if you do switch frame by webdriver (e.g. driver.switchTo().frame(objIDorIndex);)

Here are few scenarios that you can handle using selenium webdriver with javascript/jQuery.

Example - 1: 

Example - 2: 

(Case 1) In example-1, if you want to click on a "g" elements of SVG element

WebElement objectTag= findElement(By.xpath("//div[@id='imageholder']//object"));
((JavascriptExecutor) driver).executeScript("return (arguments[0].contentDocument.getElementsByTagName('g')[0]).click()", objectTag);

(Case 2) In example-2, if you want to get the title for assertion, then try as an example given below

List<WebElement> objects = findElements(By.xpath("//div[@class='contentViewer']//object"));
String objectId = objects.get(0).getAttribute("id");
WebDriver driver = getDriver();
JavascriptExecutor js = (JavascriptExecutor) driver;
String text = (String) js.executeScript("return (((document.getElementById('" + objectId + "')).contentDocument).getElementsByClassName('titleText')[0]).innerHTML");
getDriver().switchTo().defaultContent();

(Case 3) In example-2, if you want to get any specific attribute, then try something like below

List<WebElement> objects = findElements(By.xpath("//div[@class='contentViewer']//object"));
String objectId = objects.get(0).getAttribute("id");
WebElement objectTag = findElement(By.id(objectId));
String btnTitle = ((JavascriptExecutor) driver).executeScript("return arguments[0].contentDocument.getElementById('closeText').getAttribute('title')", objectTag).toString();
Assert.assertEquals(btnTitle, "Cancel to close");

(Case 4) In example-2, if you want to do any action inside the iFrame, you can use as below given example

WebElement btnDone = (WebElement) js.executeScript("return ((((document.getElementById('" + objectId
            + "')).contentDocument).getElementsByTagName('iFrame')[0]).getElementById('done'))");
btnDone.click();

Note: I have just gave few examples actions w.r.t my example html code snippet. By referring the above examples you do actions inside <object> tag as per your requirements
