使用 Shell 脚本查找 XML 文件的嵌套标签值

Question

I have an XML file of the format:

<classes>

 <subjects>
    <subject>
        <name>Operating System</name>
        <credit>3</credit>
        <type>Theory + Lab</type>
        <faculty>Prof. XYZ</faculty> 
    </subject>

    <subject>
        <name>Web Development</name>
        <credit>3</credit>
        <type>Theory + Lab</type>
        <faculty>Prof. ABC</faculty> 
    </subject>
 </subjects>

</classes>

I need to find the value of 'name' tag which is nested inside the /subject/subjects tag. How can I get the values of 'name' tag?

Shell interpreters (like sh or bash ) are not well suited to parsing xml data. You would be better off to use a tool like xmlstarlet or xmllint to select elements from an xml file and pass them back to the shell for further processing.
