UCSD CSE 232B Project

Final Report

Build

Requires gradle:

gradle build

This will run all tests, compile and place the fat jars into sub-folders of demo/, and generate the javadoc documentation

Run

XPath

• Navigate to the directory:

  cd demo/xpath/

  Save the XPath query in input.txt

  To run the XPath query, execute

  ./xpath.sh

  The resulting list of nodes will be stored in output.xml and displayed in the terminal

XQuery

• Navigate to the directory:

  cd demo/xquery/

  Save the XQuery query in input.txt

  To run the XQuery query, execute

  ./xquery.sh

  The resulting document will be stored in output.xml and displayed in the terminal

Optimized XQuery

• Run optimized XQuery:

  cd demo/optimized-xquery/

  Save the XQuery query in input.txt

  To run the XQuery query, execute

  ./optimized-xquery.sh

  The intermediate rewritten queries will be stored in rewritten.txt

  The resulting document will be stored in output.xml and displayed in the terminal

XQuery Formatter

• Run XQuery formatter:

  cd demo/formatter/

  Save the XQuery query in input.txt

  To format the XQuery query, execute

  ./formatter.sh

  The formatted query will be stored in output.txt and displayed in the terminal
