Linux remove string out of command output

How to remove/trim an string/phrasse out of Linux commang output ?


Here is an example i found so far:

cat filename | tr -d "some phrasse to delete/exclude from output"

this worked better:

cat filename | sed -e "s/phrasse to find/phrasse to replace, can be blank/g"
cat filename | sed -e "s/phrasse to find//g"
cat filename | sed -e "s/<description>URL: http:\/\/www.//g"
