Question

I have a text file and from that file i have to get specific text. What command should be used to get it?

e.g. file text is as follows:

<name>this is first line</name>
<name>this is second line</name>
<name>this is third line</name>

I have to get only text from these tags, i.e. i need “this is first line”.
