使用Augeas在XML文件中创建或更新部分

我想更新 XML配置文件中的一个部分,或者如果已经使用Augeas不存在则添加一个新部分.

XML文件如下所示：

<?xml version="1.0"?>
<security>
          <users>
            ...
            <user>
              <id>deployment</id>
              <firstName>Deployment</firstName>
              <lastName>User</lastName>
              <password>somepasshere</password>
              <status>active</status>
              <email>changeme1@yourcompany.com</email>
            </user>
          </users>
</security>

如果ID已经存在,我想更新姓氏/名字/电子邮件,如果是新ID,我想添加新用户部分.

在AugTool中我使用：

augtool> set /augeas/load/Xml/lens Xml.lns
augtool> set /augeas/load/Xml/incl /security.xml
augtool> load

我还在学习Augeas,所以这是我第一次尝试获取节点：

augtool> print /files/security.xml/security/users/user/*[ #text= 'deployment']

在用户中更新或创建新部分用户的命令是什么？

谢谢！

首先,使用最近的Augeas版本(> = 1.0.0),您可以使用–transform来设置转换.假设文件是​​./users.xml：

$augtool -r . --noautoload --transform "Xml.lns incl /users.xml"
augtool> defnode user /files/users.xml/security/users/user[id/#text="deployment"] # Create a new user entry if it doesn't exist yet, assign node to the "user" variable
augtool> set $user/id/#text "deployment"         # Set id if node was just created
augtool> set $user/firstName/#text "Deployment"  # Set firstName
augtool> set $user/lastName/#text "User"         # Set lastName
augtool> set $user/email/#text "changeme1@yourcompany.com"  # set email
...
augtool> save

您甚至可以将其转换为脚本,例如user.augtool：

#!/usr/bin/augtool -sf
defnode user /files/users.xml/security/users/user[id/#text="deployment"]
set $user/id/#text "deployment"
set $user/firstName/#text "Deployment"
set $user/lastName/#text "User"
set $user/email/#text "changeme1@yourcompany.com"

然后你可以启动：

$chmod +x user.augtool
$./user.augtool --transform "Xml.lns incl /users.xml" -r .
