How do I parse a file and use an if clause where needed?

[johngiggs]

I have a file in this format:

from:

http://domain.subdomain.tld/path/to/redirect

to:

http://newdomain.subdomain.tld/path/to/redirect/to

from:

http://domain.subdomain.tld/path2/to/redirect?code=abc

to:

http://newdomain.subdomain.tld/path2/to/redirect/to

I want to parse the file to give me Apache RewriteRules and RewriteConds where needed.

I can do the first part without stripping out the "

http://domain.subdomain.tld"

part like this:

/^from:/{from = $2}#;if ($1 ~ /\?) uri=true}
/^to:/{to = $2;print "RewriteRule ^"from" "to " [L,R=301]"}


Which results in output like this:

RewriteRule ^

http://mydomain.test.com/tip/1,page?offer=LGsn605

http://mydomain.test2.com/tip/0,page2.html

[L,R=301]

which isn't what I need because I need to strip out the beginning up until the first / on the from: line. It also needs to be updated so that when there's a query string it doesn't use the same format as when there isn't one.

The desired output for a line without a query string is this:

RewriteRule ^/tip/1,page

http://mydomain.test2.com/tip/0,page2.html

[L,R=301]

And with a query string is this:

RewriteCond %{REQUEST_URI} /path/articles/showarticle\.html [NC]
RewriteCond %{QUERY_STRING} id=mycode
RewriteRule ^(.*)$

http://mysite.testing.com/this/is/a/test?

[L,R=301]

I know for stripping out the characters I can probably use index and substr, but I'm not too sure about how to handle the if portion.

Any help would be appreciated.

Thanks,

John

A starting point:

/^from:/{from=$2;sub(/http:\/\/[^\/]*/,"",from)}
/^to:/{to=$2;if(from!~/\?/)print "RewriteRule ^"from"     "to " [L,R=301]"}

Hope This Helps, PH.

Thanks PHV! That helped strip out the domain.subdomain.tld piece!

I need to figure out how to use an if statement properly in order to parse the redirect accordingly.

Thanks,
