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.

Answer 1

curl doesn't parse XML. Try piping curl 's output to xmllint :

curl http://127.0.0.1:50000/netconf/startup-cfg.xml \
| xmllint --xpath '//futurePbRst/fsPbProviderStpStatus/text()' -
