Go through each line in a file and if that line is equal to a string, say "&#060;!--Begin--&#062;", overwrite the line with:<BR><BR>Hello<BR>&#060;!--Begin--&#062;<BR><BR>(kinda like Perl/CGI, <BR>Foreach $xxxxx_line (@xxxxx)<BR> If $xxxxx_line eq /&#060;!--Begin--&#062;/ {<BR> Do This<BR> }<BR>}<BR>)<BR>Is it possible? And if so...is it slow?
