This is my xml file:

<key name="bookstore">
<key name="books">
<key name="science">
<key name="0001">
<entry name="auther">auther A</entry>
<entry name="price">$10</entry>
</key>
<key name="0002">
<entry name="auther">auther B</entry>
<entry name="price">$20</entry>
</key>
<key name="0003">
<entry name="auther">auther C</entry>
<entry name="price">$30</entry>
</key>
</key>
<key name="music">
<key name="0001">
<entry name="auther">auther A</entry>
<entry name="price">$10</entry>
</key>
<key name="0002">
<entry name="auther">auther B</entry>
<entry name="price">$20</entry>
</key>
<key name="0003">
<entry name="auther">auther C</entry>
<entry name="price">$30</entry>
</key>
</key>
</key>
</key>


Expected XPath / Result:

#1
bookstore/books/science/0001

result:

<key name="0001">
<entry name="auther">auther A</entry>
<entry name="price">$10</entry>
</key>

#2
bookstore/books/science/0001/auther

result:
auther A

#3
bookstore/books/science

result:
<key name="science">
<key name="0001">
<entry name="auther">auther A</entry>
<entry name="price">$10</entry>
</key>
<key name="0002">
<entry name="auther">auther B</entry>
<entry name="price">$20</entry>
</key>
<key name="0003">
<entry name="auther">auther C</entry>
<entry name="price">$30</entry>
</key>
</key>

Here's an example of an XPath expression for your #1:

key[@name='bookstore']/key[@name='books']/key[@name='science']/key[@name='0001']

assuming that your context node is the document element.

Thanks a lot Paul...

I got the solution for all my xpath which I mentioned.

The solution:

#1. *[@name='bookstore']/*[@name='books']/*[@name='science']/*[@name='0001']
#2. *[@name='bookstore']/*[@name='books']/*[@name='science']/*[@name='author']
#3. *[@name='bookstore']/*[@name='books']/*[@name='science']
