a:first-child           //a[1]
ul > li:last-child      //ul/li[last()]

#id                     //*[@id="id"]   
.class                  //*[@class="class"]
input[type="submit"]    //input[@type="submit"]  
a#abc[for="xyz"]        //a[@id="abc"][@for="xyz"]  
a[rel]                  //a[@rel]    
a[href^='/']            //a[starts-with(@href, '/')]
