使用xmllint，我想通过提供服务器arguments来获取name
例如
如果/ domain / server / name为“ DEV1”，则输出为
-Xms16G -Xmx16G -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -Xloggc:GC_DEV1.log -XX:+DisableExplicitGC -XX:+PrintGCDateStamps -XX:+PrintGCDetails -XX:NumberOfGCLogFiles=20 -XX:GCLogFileSize=10240K -XX:+UseGCLogFileRotation -Dcom.conceptwave.appName=ABC
如果/ domain / server / name为“ DEV2”，则输出为
-Xms16G -Xmx16G
echo -e 'setns x=http://xmlns.oracle.com/weblogic/domain\ncat /x:domain/x:server[/x:name[text()="DEV1"]]/x:server-start/x:arguments/text()' | xmllint --shell test.xml
它给出输出/ > / > / >
cat test.xml | sed '2 s/xmlns=".*"//g' | xmllint --xpath '//domain/server[name[text()="DEV1"]]/server-start/arguments/text()' -
这会给出所有namespace not defined错误以及正确的arguments
答案 0 :(得分：0)
改用local-name（）
xmllint --xpath '//*[local-name()="server"][*[local-name()="name"]="DEV1"]//*[local-name()="arguments"]/text()' test.xml
xmllint --xpath '//*[local-name()="server"][*[local-name()="name"]="DEV2"]//*[local-name()="arguments"]/text()' test.xml
