I am in search for a good xpath example.
Let say I have, this xml file
<?xml version="1.0"?>
<catalog>
<book id="bk101">
<genre><s>Computer</s></genre>
<price><f>44.95</f></price>
<publish_date><d>2000-10-01</d></publish_date>
<description><s>An in-depth look at creating applications
with XML.</s></description>
</book>
</catalog>
How can I extract only the price of a book which has a genre of "computers"?
How can I extract, price, description of book id"bk101" ?
