java - Webdriver findElements By xpath -

1)i doing tutorial show how findelements xpath works. know why returns texts following <div> element attribute id=container.

code xpath: by.xpath("//div[@id='container']

2) how should modify code return first or first few nodes follow parent note e.g. first node 'home', first few node like, home, manual testing , automation testing.

thanks advise , help!

here code fragment tutorial:

your questions:

q 1.) know why returns texts following div?
should not , think in not. returns div 'id' attribute value equal 'containter' (and children of this). printing results ele.gettext() gettext return text content of children of result.

get visible (i.e. not hidden css) innertext of element, including sub-elements, without leading or trailing whitespace.
returns:
innertext of element.

q 2.) how should modify code return first or first few nodes follow parent note
not clear looking for. example:

<p1> <div/> </p1 <p2/>  

the following parent of div p2. be:

 //div[@id='container'][1]/parent::*/following-sibling::*  

or shorter

 //div[@id='container'][1]/../following-sibling::*  

if looking first 1 extent expression "predicate" (e.g [1] - first one. or [position() < 4]for first three)

if looking first child of first div:

//div[@id='container'][1]/*[1] 

if there 1 div id looking first child:

   //div[@id='container']/*[1] 

and on.
