You can leverage the XML SQL functions to extract from XML using the database, see the blog post below;
https://blogs.oracle.com/warehousebuilder/entry/leveraging_xdb
For example to extract information from your XML document the following SQL can be generated from OWB;
select extractValue(value(s), '/book/author'),
extractValue(value(s), '/book/year'),
extractValue(value(s), '/book/price') from
( select XMLType('<bookstore>
+<book category="COOKING">+
+<title lang="en">Everyday Italian</title>+
+<author>Giada De Laurentiis</author>+
+<year>2005</year>+
+<price>30.00</price>+
+</book>+
+<book category="CHILDREN">+
+<title lang="en">Harry Potter</title>+
+<author>J K. Rowling</author>+
+<year>2005</year>+
+<price>29.99</price>+
+</book>+
+<book category="WEB">+
+<title lang="en">Learning XML</title>+
+<author>Erik T. Ray</author>+
+<year>2003</year>+
+<price>39.95</price>+
+</book>+
+</bookstore>') adoc from dual+) r,
table(XMLSequence(extract(r.adoc, '/bookstore/book'))) s;
