我正在尝试运行以下命令以从文件中获取上述输出

grep -i -A3 'com.mulesoft.connectors\|org.mule.connectors' pom.xml

当上述条件匹配时，我想打印如下值，例如

我正在尝试从下面的命令中捕获所有匹配的模式

grep -i -A3 'com.mulesoft.connectors\|org.mule.connectors' pom.xml 

我正在尝试通过此命令获取 artifactId 和版本

预期输出:

artifactId value,version
------------------------
mule-ibm-mq-connector,1.8.3
mule-file-connector,1.5.2
mule-salesforce-connector,10.8.1
mule-email-connector,1.1.8
mule-connector,1.4.1

Answer 1

像 xmllint 这样的 XML 解析器可以更好地完成这项任务，但是由于某些原因您不能安装新工具，您可以考虑使用 grep | gnu-awk 解决方案:

grep -i -A3 'com\.mulesoft\.connectors\|org\.mule\.connectors' pom.xml |
awk -v RS='--' -v OFS=, 'BEGIN {print "artifactId value,version"} 
{gsub(/<\/?[^>]+>/, ""); print $2, $3}'

artifactId value,version
mule-x12-connector,2.6.2
mule-objectstore-connector,1.1.7
mule-http-connector,1.5.6
mule-file-connector,1.3.3
mule-ibm-mq-connector,1.6.3
mule-sftp-connector,1.4.0
mule-email-connector,1.4.1
