用sed替换xml值

Question

我想替换XML文件中的值.示例XML

<Console>
                <!-- REQUIRED PARAMETERS -->
                <!-- Enter the node that you are running the installation program from. This value must be a fully qualified name, which includes a host name and domain name. For example, node001.server.name.com.-->
                <node>node.sample.ibm.com</node>

                <!-- Enter the domain name of the cluster as a single dot-separated string. For example, server.name.com. -->
        <sso-domain-name>sample.ibm.com</sso-domain-name>

        <!-- Set this property to true if your InfoSphere BigInsights Console uses HTTPS. Otherwise, enter false. -->
                <https>false</https>

        <!-- management-console-port specifies which port is used by the Management Console. -->
        <management-console-port>8080</management-console-port>

我想取代价值.我尝试了以下,但它不起作用.任何帮助赞赏.

sed -i "/<Console>/,/<\/Console>/ s/<node>[0-9][a-z]\+/<node>newvalue

Answer 1

sed -i -e '/<Console>/,/<\/Console>/ s|<node>[0-9a-z.]\{1,\}</node>|<node>newvalue</node>|g' YourFile

我假设价值在您的标签之间,并且只包含小写字母,点和数字(基于您的样本和尝试).如果扩展,只需在类中添加缺少的字符[0-9a-z._-A-Z:],也许子类[:space:]

如果newvalue是一个变量的内容,不要忘了使用双引号和转义字符&,\和sed的分离s动作(默认是/和|我的代码)

Answer 2

你可以使用xmlstarlet:

xmlstarlet ed -u //Console/node -v 'new value'

(或类似的东西)
