i have a file called startup-cfg.xml containing 

```
<futurePbRst>
  <fsPbProviderStpStatus>enabled</fsPbProviderStpStatus>
</futurePbRst>
<fsPbRstCVlanBridgeTable>
  <fsPbRstCVlanBridgeEntry>
    <fsPbRstPort>1</fsPbRstPort>
  </fsPbRstCVlanBridgeEntry>
</fsPbRstCVlanBridgeTable>
<fsPbRstCVlanPortInfoTable>
  <fsPbRstCVlanPortInfoEntry>
    <fsPbRstPort>1</fsPbRstPort>
    <fsPbRstCepSvid>1</fsPbRstCepSvid>
  </fsPbRstCVlanPortInfoEntry>
</fsPbRstCVlanPortInfoTable>

i want to fire a curl command to get a particular tag value from this xml file.how can i do it?

running the command curl <http://127.0.0.1:50000/netconf/startup-cfg.xml> gives the entire file contents as output.
