How to get page-source of an element in mobile native app by selenium script?

Question

I'm using Appium for automation of mobile application and I want is just the pagesource of an element of a native app. I have googled a lot and found that its possible for webpages but did not get any solution for mobile's native app. like below examples.

elem.getAttribute("innerHTML");

OR

WebElement element = driver.findElement(By.id("foo"));
String contents = (String)((JavascriptExecutor)driver).executeScript("return arguments[0].innerHTML;", element);

Solution

There is getPageSource() method:

driver.getPageSource();

Update

To get source code of specific element (including element's tag):

element.getAttribute('outerHTML')

I don't want page source of entire page, I just want the page source of a specific element. Something like <h1 name="title">Title</h1>

@pr4bh4sh, element.getAttribute('innerHTML')?

[Kirill]

Probably you need this: element.getAttribute('innerHTML')

[kiedysktos]

for iOS it doesn't work. "UIAElements don't have the attribute 'outerHTML'" - that's what Appium says

@kiedysktos, try to change context from native to web.

For CodeceptJS: await I.grabSource()
