selenium - How can i write my own xpath from the html code -

i have followig html code , want x path text "analytics & research"

<div id="llcompositepagecontainer" class="column-wrapper">     <div id="compositepagetitlediv">         <h1 class="page-header">analytics &amp; research</h1>     </div>  

i getting following xpath using chrome, didnt work.

//*[@id="compositepagetitlediv"] 

this code

webelement header = driver.findelement(by.xpath("//div[@id='llcompositepagecontainer']/div[@id='compositepagetitlediv']/h1[@class='page-header']"));          string header2 = header.gettext();  system.out.println(header2); 

and following error getting

exception in thread "main" org.openqa.selenium.nosuchelementexception: unable find element xpath == //div[@id='llcompositepagecontainer']/div[@id='compositepagetitlediv']/h1[@class='page-header'] (warning: server did not provide stacktrace information) command duration or timeout: 10.34 seconds documentation on error, please visit: http://seleniumhq.org/exceptions/no_such_element.html

please try use below xpath:

driver.findelement(by.xpath(".//div[@id='compositepagetitlediv']/h1")).gettext(); 

if element inside iframe. use below code:

// switching frame driver.switchto().frame(<name>);  // storing value of analytics & research string text = driver.findelement(by.xpath(".//div[@id='compositepagetitlediv']/h1")).gettext();  // switching original window driver.switchto().defaultcontent(); 

hope helps.
