我试图从pom.xml文件中获取多个字符串.例如，下面是xml文件的内容

</project>我正在尝试运行下面的命令，以便从文件中获得上述输出
grep -i -A3 'com.mulesoft.connectors\|org.mule.connectors' pom.xml当上述标准匹配时，我想打印如下所示的值，例如
我试图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 从这个命令中，我试图获得artifactId和版本

像xmllint这样的XML解析器可以更好地完成这项任务，但是您无法安装一个新工具，因为您可能会考虑使用这个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

在显示的示例和尝试中，请尝试遵循单个awk代码(这里不使用grep，并且在单个awk内部根据需要处理匹配、条件和打印值)。在GNU awk中编写和测试，它使用GNU awk' match函数从捕获组值创建数组(这些值是由用于解决方案的regex创建的)。
这是用于理解目的的在线演示，regex创建了三个捕获组，其中第一个用于检查条件，如果第一个捕获组的条件满足OP的条件，rest 2将被打印。
awk -v RS="^$" '
{
while(match($0,/<groupId>([^<]*)<\/groupId>\n[[:space:]]*<artifactId>([^<]*)\
<\/artifactId>\n[[:space:]]*<version>([^<]*)<\/version>/,arr)){
if(arr[1]=="com.mulesoft.connectors" || arr[1]=="org.mule.connectors"){
if(++count==1){
print "artifactId value,version"
}
print arr[2]","arr[3]
}
$0=substr($0,RSTART+RLENGTH)
}
}

回显"${input_data}“\ mawk NF=NF FS='^>+>‘OFS='，’\RS=‘(\n^n+\n+)？(^\n+\n+\t+)？
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标题行应该是微不足道的。
