We assume that you know that exactly the same thing works in awk:
Code:
echo "This html code <text blah >contains <garbage blah blah >. All tags must go, <text > but some must be replaced with <garbage blah blah > without easing other info." |
    awk '{sub("<garbage[^>]*>", "important info")}1'

to make a substitution for the first occurrence producing the output:
Code:
This html code <text blah >contains important info. All tags must go, <text > but some must be replaced with <garbage blah blah > without easing other info.

or:
Code:
echo "This html code <text blah >contains <garbage blah blah >. All tags must go, <text > but some must be replaced with <garbage blah blah > without easing other info." |
    awk '{gsub("<garbage[^>]*>", "important info")}1'

to make a substitution for all occurrences producing the output:
Code:
This html code <text blah >contains important info. All tags must go, <text > but some must be replaced with important info without easing other info.
