4.15 Assignment #2: Simple Queries

due: Wednesday, Oct 15

Write a SAX Java program that reads a query file and a content file, and outputs the data from the content file that satisfies the query. Both files should be in XML format. The query language should relate only to element names, attribute names, attribute values, and text. The design of the query language is for you to decide.

Example: The following files might produce the output “Blue for fun. Blue for sky.”.

<?xml version="1.0"
      encoding="UTF-8"?>
<query>
  <element name="foo">
    <attribute name="color"
               value="blue" />
  </element>
</query>

<doc>
<foo color="red">Red for love.</foo>
<foo color="blue">Blue for fun.</foo>
<foo>Color less for relax.</foo>
<foo color="blue">Blue for sky.</foo>
</doc>
