/html/body <- root of the page to the html tag to the body tag<br />
<br />
walking, 'traversing' a path<br />
<br />
/html/body/div<br />
entering the root of the page, walking into the html tag, down into body, into the first div we encounter<br />
<br />
What about the second div?<br />
/html/body/div[2]<br />
<br />
What about grabbing any div we find?<br />
//div<br />
<br />
What about any div, with the id of first_section?<br />
//div[@id='first_section']<br />
<br />
What about the second list item, beneath the div with the id, first_section?<br />
//div[@id='first_section']//li[2]<br />
<br />
What if we do not know what the tag is, but know we want the id of 'second_section'?<br />
//*[@id='second_section']<br />
<br />
What about grabbing the element with the id of 'first_item'?<br />
//*[@id='first_item']<br />
<br />
What about grabbing the element above that? -- what does it grab?<br />
//*[@id='first_item']/../<br />
<br />
And the one above that? -- what does it grab?<br />
//*[@id='first_item']/../../<br />
<br />
And the one above that?<br />
<br />
How about grabbing any option item under a select tag?<br />
//select//option<br />
<br />
And the entire document?<br />
