function_description=This function returns an array of strings, for efficiency purposes, not a map, representing the node(s) which xpath has selected for you in the html document. Unlike a map, arrays will encounter an "out of bounds" exception when attempting to add new elements to it, do note the difference. This function will return an empty array if no nodes match the selector. In the event the selector uses invalid syntax, this function will error with "invalid xpath expression"|

For example, if you used "intriguing puzzle box" from your inventory and ran the above script, you'd see the following output:

option 3:Turn the rear face counterclockwise.
option 4:Push the right face.
option 5:Turn the right face counterclockwise.
