xml - what is the difference between these in xpath? -


i new xpath can let me in detail difference between /bookstore/* , /bookstore in xpath?

let example input

<bookstore>     <book>       <title lang="en">harry potter</title>       <price>29.99</price>     </book>     <book>       <title lang="en">learning xml</title>       <price>39.95</price>     </book> </bookstore>  <bookstore>      <book>       <title lang="en">harry potter1</title>       <price>29.999</price>     </book>      <book>       <title lang="en">learning xml1</title>       <price>39.955</price>     </book>  </bookstore>

what output in both cases? in advance.

the expression /bookstore/* select children, /bookstore select node itself.

for instance, /bookstore/* select all child elements under /bookstore, may end collection of elements. note in case more complex expression /bookstore/book/* , there multiple /bookstore/book elements, children of matching nodes selected.

the expression /bookstore select element(s) /bookstore. similarily above, such select may result in collection of elements if it's down path /bookstore/book.
