我在solaris上尝试了以下命令但失败了:
错误输出:
wladmin@remhost:$ sed -n '/<Resource/{:a; N; /DB01/!ba; s/.*password="\([^"]*\)".*/\1/p}' /web/bea_apps/perf/Tomcat_Home_v9.0.56/TomcatNode01/conf/server.xml
Label too long: /<Resource/{:a; N; /DB01/!ba; s/.*password="\([^"]*\)".*/\1/p}
期望的结果:
O9jYL3yhwMF_Ep8P
VEL_CAN_WEB_USER
host36db06v.mybank.com:1521:DB01
我最终会将解决方案交给ansible。
请协助。
答案1
这里是密码的代码。
调整它以获得其余的:
xmllint --xpath 'string(//Resource[@auth="Container" and contains(@url, ":DB01")]/@password)' file.xml
输出
O9jYL3yhwMF_Ep8P
表达式为xpath。
答案2
要回答主题中的问题,请在您的:
/<Resource/{:a; N; /DB01/!ba; s/.*password="\([^"]*\)".*/\1/p}
sed
脚本,使用传统的sed
实现(源自 70 年代原始实现的实现,例如 Solaris),:a; N; /DB01/!ba; s/.*password="\([^"]*\)".*/\1/p}
正在定义(试图定义)一个名为 的分支标签a; N; /DB01/!ba; s/.*password="\([^"]*\)".*/\1/p}
,即;
不将:
命令与N
命令分开,它是命令的一部分。标签名称。b
,命令也是如此t
。
它甚至曾经是 POSIX 所要求的,并且只是放宽了(在我的请求) 在2016年版标准。
:
因此,在, b
,之后的同一行上不能有任何其他命令t
。
GNUsed
不允许;
在标签名称中使用,但仍然允许;
在 , 后面使用文件名w
,r
这s///w
仍然是 POSIX 所要求的。例如,w file;d
写入名为file;d
.所以那些 (and#
和}
) 后面也不能跟任何东西。
脚本中不兼容/不便携的另一件事是您没有在前面添加}
换行符;
。
所以你需要:
sed -n '
/<Resource/{
:a; N; /DB01/!ba
s/.*password="\([^"]*\)".*/\1/p
}'
或者,如果您需要一行:
sed -n -e '/<Resource/{:a' -e 'N;/DB01/!ba' -e 's/.*password="\([^"]*\)".*/\1/p;}'
答案3
使用xq
(部分安德烈·基斯柳克的yq
分布;一组构建在 JSON 解析器之上的解析器jq
)并传递一个字符串,该字符串将用于匹配相关Resource
部分中的正确 URL:
query_string=DB01
xq -r --arg query "$query_string" '
.Server.GlobalNamingResources.Resource |
map(select(."@auth" == "Container" and (."@url" // empty | endswith($query)))."@password")[]' file.xml
正如您所看到的,该表达式的核心(根据和属性选择jq
相关条目)的读法与以下解决方案类似:Resource
auth
url
吉尔斯的回答。这里的区别在于,该jq
工具(xq
包装)允许使用--arg
.这意味着我们可以参数化命令,而无需将 shell 数据注入表达式中。
我还选择使用 测试 URL endswith()
,因此用户提供的字符串必须与结尾的网址。
运行上述命令将返回字符串O9jYL3yhwMF_Ep8P
。
使用Mike Farah 的yq
解析器为了解析 XML,我们可以做类似的事情:
query=$query_string yq '
.Server.GlobalNamingResources.Resource |
map(select(."+@auth" == "Container" and ."+@url" == "*" + env(query))."+@password") | .[]' file.xml
这里的区别在于,我们yq
通过环境变量传递用户提供的值query
,并在表达式中进行模式匹配(这意味着我们希望给定的字符串不是图案)。另请注意,Mikeyq
使用的 XML 属性格式略有不同(带有前缀+
)。
