Java XML Grepper

You want to get a value from your xml file using XPath? Then this is for you. Easily grep the version from your POM.

 

Is this for me?

If you want to grep e.g. the version of a pom.xml file to commandline then this is for you.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>io.codeclou</groupId>
  <artifactId>java-xml-grepper</artifactId>
  <version>1.4.5</version>
</project>

 

Usage

With current folder containing a pom.xml file and you want to print out the version on commandline. The -x parameter accepts XPath expressions that can be cast to String.

# INSTALL
curl -L -o java-xml-grepper.jar \
     https://github.com/codeclou/java-xml-grepper/releases/download/1.0.0/java-xml-grepper.jar

# RUN
java -jar java-xml-grepper.jar \
     -f pom.xml \
     -x /project/version
     
# PRINTS (example)
1.0.1

If something happens like parsing errors, file not found a.s.o the exit code will be 1. Otherwise the exit code will be 0 and it will only print the grepped output.

 

Demo

git clone https://github.com/codeclou/java-xml-grepper.git src
cd src

curl -L -o java-xml-grepper.jar \
     https://github.com/codeclou/java-xml-grepper/releases/download/1.0.0/java-xml-grepper.jar

java -jar java-xml-grepper.jar \
     -f pom.xml \
     -x /project/version

# Should print the version
