What is XPATH?

• XPath is used to navigate through elements and attributes in an XML document.
• XPath can locate any type of information in an XML document with one line of code.
• These one liners are referred to as "expressions," and every piece of XPath that you write will be an expression.
• Xpath contains library of standard function.
• Following example demonstrate the xpath expression.

inventory.xml

if we wanted to know the amount of chips from left side xml , the XPath expression would be:           

inventory/snack/chips/amount 

If we wanted to select the price of pop, we would have to make an even longer path of elements to reach our final destination.

inventory/drink/pop/price
