求助！Shell如何修改xml中的标签

Question

一个a.xml如下：<?xml version="1.0" encoding="UTF-8"?>
   <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-surefire-plugin</artifactId>
                        <configuration>
                                  <testFailureIgnore>true</testFailureIgnore>
                                  <skipTests>true</skipTests>
                        </configuration
</plugin>
我想要把  <skipTests>true</skipTests> 改成      <testNGArtifactName>com.bb.private.test:testng</testNGArtifactName> 请问如何改？
以下是我的写法，但不行，请懂的朋友指教：）cat a.xml | sed 's/<skipTests>true</skipTests> /<testNGArtifactName>com.bb.private.test:testng</testNGArtifactName>/' > a.xml.bak
   mv -f a.xml.bak  a.xml

Answer 1

#!/bin/sh
cat a.xml | sed 's/<skipTests>true<\/skipTests>/<testNGArtifactName>com.bb.private.test:testng<\/testNGArtifactName>/g' > a.xml.bak
mv  a.xml.bak a.xml试试
