str: {<A HREF="http://www.rebol.com/">REBOL website</A>}
parse str [
thru "<A HREF="
thru ">"
start-replace:
to </A>
end-replace:
(change/part start-replace "REBOL Technologies www site" offset?
start-replace end-replace
end-replace: index? start-replace)
:end-replace
to end
]
by assigning the value - start: you tell parser to mark the input, so we
marked start and end of the part of string we want to change ...
then I used change/part, which will change the string. The function seems to
be intelligent enough to insert rest of the string and return the series
behind the point of insertion.
I am not sure if required, but by putting :end back into parser we reassign
position and tell parser to start right from that position
